201037958 六、發明說明: 【發明所屬之技術領域】 本發明涉及太陽能技術領域,更具體地,涉及用於將 電源從若干類型的太陽能轉換爲使其在各種應用中可以利 用的方法和設備。本發明大槪從三個不同態樣提供能夠用 來從太陽能電池、太陽能板、或成串面板(strings of panels ) 獲得最大功率的技術和電路,以便該功率能夠用於DC或 AC用途,可能用於傳輸至電力網等。這三個態樣或許能夠 〇 獨立存在,並且涉及:1)以複合方式提供電源轉換,2) 建立能夠在不同過程(differingprocesses)間交替的系統, 以及3)能夠實現較常規系統高得多的轉換效率的系統。 【先前技術】 太陽能是最理想的可再生能源之一。近年來,它被奉 爲我們日益工業化的社會最有前景的能源之一。雖然理論 上太陽能的量遠超一一即使不是全部也是大部分一一其他 能源(可再生或不可再生)的量,但利用此種能源存在巨 〇 大的挑戰。通常,太陽能面臨完全發揮其作用的許多限制。 一方面,如何能提供與其成本相稱的電輸出是其面臨的挑 戰。本發明提出的一個主要態樣即顯著降低太陽能電利用 化的成本,使其成爲合算的電源來源。 最有效將太陽能轉換成電能的方式之一是利用太陽能 電池。該裝置經光電效應產生光生直流電。通常此類太陽 能電池彼此電連接以構成一個太陽能板或PV (光電)板的 電池組。PV板通常串聯連接,以在合理的電流時提供更高 -4- 201037958 的電壓。這可降低電互聯的損耗。由於使用的電源轉換器 能更有效地利用更高的電壓’太陽能電池或太陽能板或甚 至其組合的輸出一般是轉換成最有效的電源。常規電源轉 換器甚至在其輸入端使用MPPT(最大功率追蹤器)電路來 從一個或多個或甚至是一串連接板處提取最大量功率。但 是該方法的問題是由於通常由PV板起到電流源的作用以 及當串聯連接時,最小功率板將限制透過任意板的電流。 此外’歷史上的太陽能電池均用諸如矽PN結的半導體 〇 製成。這些結或二極體將太陽光轉換成電能。這些二極體 具有低電壓輸出的特性’通常在0.6伏的數量級。這種電 池與正向二極體並聯而起類似電流源作用。此類電池的輸 出電流可是許多結構因素的函數,通常與陽光量成正比。 這種太陽能電池的低電壓將難以轉換成適於供電至電 力網的功率。通常將許多二極體串聯在光電板上。例如, 一種可能的結構可具有以串聯方式連接以獲得21.6伏的 36個二極體或板。實際上這種具有旁路二極體的板還有互 〇 W 連損耗,因此在其最大功率點(MPP)處僅能產生15伏的 電壓。對於具有更多這種板的一些更大的系統來說,即使 15伏也不足以基本無損耗地在電線上傳輸。此外,現在典 型的系統以串聯方式合倂多個板來提供100伏的電壓,以 使PV板和電源轉換器之間的傳導損耗最小化。 然而,有關電態樣面臨的問題是找到轉換器合適的輸 入阻抗以從此種成串PV板處獲得最大功率。在最大功率點 上提取功率通常稱爲MPP追蹤。然而,一部分此類系統存 201037958 在這裏將討論的一些限制。首先,PV板可起到電流源的作 用。因此,產生最小電流的板將限制透過整排板的電流。 在不理想的情況中,如果一個較差的板產生了相對較小的 電流,它將被其他板反向偏置。反向二極體可設置在每個 板的交叉處來限制此種情況的功率損耗並保護板不被反向 擊穿。 在系統中,至少出現過以下問題並導致在太陽能轉換 中出現一定程度的損失: A. 板間的不均勻性 B. 半陰的天氣 C. 灰麈或累積物阻礙太陽光 D. 板的損壞 E. 隨著時間流逝板出現不均勻的退化 當昂貴的PV面板串聯使用時,也可能很麻煩,最脆弱 的板將限制從任意其他板流出的電流。不利的是,串聯連 接的目的是獲得足夠高的電壓以更有效地透過地域分佈將 功率傳輸至載荷負載處,諸如並聯型轉換器。此外,在許 多系統中,PV板可置於屋頂上,諸如用於居住相關的設 備。轉換器通常置於距離屋頂一定距離的地方,諸如透過 功率計等。因此在實施例中,需要提出串聯連接板且不產 生最小功率板造成的損耗或任意串列並聯的連接方式。還 需要能在不考慮連接結構(串聯或並聯等)的同時使用不同 的板。 光電能量轉換的技術被認爲是徹底發揮太陽能作用最 201037958 大的限制。已經提出了在沿著MPP電路的每個板上使用 DC/DC轉換器作爲太陽能轉換方法的一種嘗試,以提高使 用太陽能板串列時的能量收穫率。然而,這種嘗試已經導 致了無法接受的低效率,使該方法不具實際意義。在某種 程度上,這些技術已經被遺漏考慮此種問題。例如,在G.R. Walker、J. Xue 和 P. Sernia 的題爲 “PV String Per-Module Maximum Point Enabling Converters”的文章中,作者提出 效率損耗是不可避免的,但其提出的模組仍然具有一定的 〇 優點,儘管它獲得了低的效率。類似地,在兩個相同作者 G.R. Walker 和 P. Sernia 的題爲 “Cascaded DC-DC Converter Connection of photovoltaic Modules”的文中顯示所需要的 技術總是處於不利的效率。這些文獻中甚至還掲示了效率 與功率的曲線圖,其顯示的滿功率接近91%。簡單來說, 透過低效率轉換器的高成本的運轉PV板在市場上是不可 接受的。 另一個尙未硏究透的問題是巨大串列串聯的PV板具 〇 w 有差異度極大的輸出電壓,使得驅動電力網的轉換器狀態 需要在較大範圍內調整導致其效率降低。還有一個問題是 轉換器部分不供電給電力網(grid)期間將使該階段的輸 入電壓提高甚至超出可控限度。或相反地,即使在此期間 的電壓不超過可控限度,但最終運轉電壓仍將大大低於轉 換器效率的理想點。 此外,還有啓動和保護的問題,其將顯著提高整個太 陽能轉換方法的成本。還具有其他影響太陽能安裝系統成 201037958 本平衡(BOS)的次要因素。因而,太陽能的電需求的至 少一個態樣是提高電系統轉換階段的效率。本發明恰好提 供了這方面的必要改善方案。 【發明内容】 如本發明的發明領域之,本發明包括可以不同方式組 合的各個態樣。隨後的描述將列舉各部件並闡述本發明的 一些實施例。用基礎的實施例來描述各部件,然而,應理 解它們可以任意方式和任意數量進行組合以產生其他的實 施例。描述的多種實施例和優選的實施例不應理解爲限制 本發明,而僅僅是明確地描述系統、技術和應用。此外, 應該理解本說明書支持並包含所有各種實施例、系統、技 術、方法、裝置和具有所揭示元件的任意數目、具有單獨 的各元件的應用、以及也具有在此或任何隨後應用中所有 各種元件的任意和所有各種改變和組合的應用。 在各種實施例中,本發明揭示了可實現本發明一些目 的的成果、系統和不同的原始示例性結構。系統具有交替 方式的光電轉換、高效率轉換設計以及多峰轉換的技術。 —些結構可將PV板與MPP甚至與雙模功率轉換電路組合 使用以獲得儍選的功率調節器(PC)部件。如下前述,這 種功率調節器可以串聯或並聯或串/並聯的方式任意組合 連接’並設計成使太陽能板能主要地或甚至長期地進行它 們的滿功率輸出。即使具有不同輸出特性的不同類型的板 仍可組合使用並獲得每塊板的最大功率。在一些設計中, 用串聯串列來獲得電傳輸有用的高電壓,設計每個功率調 201037958 節器的目的是產生其最大功率。 在實施例中’本發明允許每塊板均單獨地產生其最大 功率,因而能收穫整個系統的更多的總能量。該系統在每 塊板上設置了 MPP電路和能量轉換電路。這些電路是能發 揮若干功能的低廉的簡單電路。首先,設計該電路來提取 每塊板可用的最大功率。其次,設計該電路來改變當與串 聯中的其他板組合時天然存在的阻抗。還可在並聯連接的 板甚至單個電池或面板串列中配置該電路。如此配置的實 〇 施例可獲得較高的電壓輸出(例如400伏)。另外,這種結 構也易於控制超壓或進行其他保護,可具有或不具有控制 系統避免超壓或其他情況的回饋部件。 在板上額外配置單個MPP電路在成本上並沒有太大的 增加,在一些實施例中可代替電源轉換器實現相同功能。 該電路還可加入PV板中,且不需要在網結轉換器中重複使 用,因而這將使相同的總電路獲得顯著的優勢。在實施例 中還可用數個小的MPP轉換器取代一個大的轉換器,這將 ^ 獲得更高的能量收益。 【實施方式】 [實施例] 如上前述,本發明揭示了可單獨使用和與其他相組合 使用的多種態樣的內容。最初的想法是根據本發明的功率 調節器的一個實例可與任意以下原理和電路組合使用:交 替處理轉換器(a 11 e r n a t i v e p r 〇 c e s s c ο n v e r t e r )、雙模光電 轉換器、極高效的光電轉換器、多峰光電轉換器、將最大 201037958 功率追蹤器(MPP或MPPT)倂入上述部件中,以及包括 可控界限的諸如可控輸出電壓、輸出電流以及輸出功率的 界限的實施例。所有這些都應當從廣義上以及借助顯示工 具基礎應用(display initial applications for implementation) 的實施例來理解。所有這些態樣的基礎益處將單獨討論以 及在如下討論中與代表一級拓撲學而不是僅僅是根據上述 的內容進行組合討論。 圖1顯示說明本發明的太陽能轉換基礎原理的太陽能 〇 系統之一實施例。如其所示,它包括注入光電DC-DC電源 轉換器(4)的太陽能源(1),電源轉換器(4)將轉換後 的輸出供給主要與電力網(grid )( 10)相連接的光電DC-AC 轉換器(5)。可以理解,太陽能源(1)可以是太陽能電池、 太陽能板或甚至面板串列。無論如何,太陽能源(1)能夠 提供DC光電輸出(2)。該DC光電輸出(2)可作爲DC-DC 電源轉換器(4)的DC輸入。 根據通常由轉換器功能控制電路(8 )指示的性能來控 ® 制DC-DC電源轉換器(4)的運轉。本技藝人士應理解轉 換器功能控制電路(8)的含義很廣,可以是真實的電路硬 體或固件或軟體來實現預期的控制。類似地,可以認爲 DC-DC電源轉換器(4)能夠代表光電DC-DC能量轉換電 路。在這點上,很可能必需硬體電路,然而,應該理解“電 路”一詞仍包括硬體、固件及軟體的組合。 如圖1所示,各種部件可彼此相連。直接連接僅僅是 一種方式,其中各種部件可彼此響應,即,一個部件的若 -10- 201037958 干效應可直接或間接引起另一個的效應或改變。DC-DC電 源轉換器(4)的作用是轉換其輸出並提供轉換後的DC光 電輸出(6),作爲多種設計的DC-AC轉換器(5)的輸入。 該DC-AC轉換器(5)可包括或可不包括在太陽能電源系 統的實施例中。如果包括,它的作用是完成將DC電源轉 換成轉換後的DC (7)諸如光電AC電源輸出(7)的步驟, 該輸出可用於例如透過所謂AC電力網介面(power grid interface )(9)連接的電力網(10)。這樣,系統可產生 0 DC光電輸出(6),作爲一些類型的DC-AC轉換器(5)的 輸入。轉換輸入的步驟應理解爲包括和產生來自任意直流 電流信號的任意交替信號,即使該信號本身並不完美或並 不十分穩定。 如圖2和圖6所示,單個太陽能源(1)(電池、板或 模組級的)可組合使用以產生成串電連接的來源。這種組 合可透過串聯或並聯連接作出回應。如圖2和圖6所示, 連接多個可形成成串列電連接項目。諸如電連接的太陽能 〇 V 板(11)串列。如圖2所示,每個這種串列本身均是從一 個部件到非常大的組合,形成光電陣列(1 2 )或多個組合 的太陽能源。透過物理的或電的總體佈局,若干這些電池、 板或串列可以彼此相鄰,使得它們暴露在較爲類似地電 的、機械的、環境的、太陽曝光(或非太陽的)的條件下。 如圖2示意性顯示,在使用大陣列情況下,須加入高電壓 的DC-AC太陽能轉換器以及三相高電壓轉換AC光電輸出。 如針對電串聯的組合所顯示,可以組合輸出,因此它 -11 - 201037958 們的電壓將提高但它們的電流將不變。相反,還可能出現 電並聯的組合。圖2和6示出連接來實現串聯組合或串聯 部件諸如經轉換的DC光電輸出(6 )以產生經轉換的DC 光電輸出至DC-AC轉換器(5)的實施例。如其所示,可 串聯獲得經轉換的DC光電輸出(6),隨後產生經轉換的 DC光電輸出(13),作爲經轉換的DC光電輸入(14)供 至一些類型的光電DC-AC轉換器(5)或其他負載器。再 次,每個太陽能源(1 )可以是電池、板、串列或甚至陣列 〇 級的。可以理解的,也可實現並聯以及並聯連接轉換器或 其輸出的步驟。 如上前述,可構造電路和系統自太陽能源(1)提取更 多功率。在電方面可利用 MPP電路或最大功率追蹤器 (MPPT )在一個或多個太陽能電池、板或串列的最大功率 (MPP )處的運轉實現提取更多電源。因而,在實施例中, 根據本發明的太陽能系統包括:具有能量轉換電路的MPPT 控制電路。還可包括隨後之範圍限制電路。 〇 圖3和4顯示最大功率點,可配置最大功率追蹤 (MPPT )電路來找到自給定板或其他太陽能源(1)提取 功率的最佳點。作爲背景,應理解在實驗室中測量的板具 有圖3顯示的電壓和電流的關係。縱軸是單位爲安培的電 流。橫軸是單位爲伏的電壓。圖4顯示用數倍於電流的電 壓來獲得功率的情況。現在縱軸是功率。這裏一個使用的 MPPT電路的實例的目的是賦予板適當的負載電阻或更精 確的阻抗,運轉板提供其功率峰。可以從圖表看出當板產 -12- 201037958 生接近15伏和8安時該板出現測定條件下的最大功率。這 可由最大光電功率轉換器功能性控制電路(15)確定,該 電路是轉換器功能性控制電路(8 )運轉模態(modality ) 的一部分或全部。這樣,轉換器或轉換的步驟可獲得光電 DC-DC能量轉換或最大光電功率轉換步驟的最大光電功率 模態。如下前述,可透過開關以及任務循環開關來實現上 述情況,同樣地,該系統也可完成最大光電功率任務循環 開關或最大光電電壓確定性任務循環開關的步驟。 〇 本領域技術人員將理解:有多種電路結構可用來獲取 MPP資訊。一些可根據觀察短路電流或開路電壓。其他類 型的方案可稱爲擾動和監測(P&0 )電路提及。該P&0方 法可與稱爲“爬山(hill climb) ”的技術組合使用以獲取 MPP。如以下解釋的,可單獨確定用於每個來源的、相鄰 來源的 '或整個串列的MPP以運轉實現最好的運轉。因而 組合系統的實施例可單獨利用板(理解爲包括任何來源級 別的)專用的最大光電功率點轉換器功能性控制電路 ❹(16)。 無論是否是單個構成的,在p&0方法中’可配置類比 電路來在板上產生波紋電壓。利用簡單的類比電路還能獲 得板電壓及其一階導數(V,)’以及板功率及其一階導數 (P,)。用兩個導數和簡單的邏輯能按照以下調整板上的負 載: -13- 201037958201037958 VI. Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to the field of solar energy technology and, more particularly, to a method and apparatus for converting a power source from several types of solar energy to make it useful in various applications. The present invention provides techniques and circuits that can be used to obtain maximum power from solar cells, solar panels, or strings of panels from three different aspects so that the power can be used for DC or AC purposes, possibly Used for transmission to power grids, etc. These three aspects may be independent and involve: 1) providing power conversion in a composite manner, 2) establishing a system that can alternate between different processes, and 3) enabling much higher performance than conventional systems. A system that converts efficiency. [Prior Art] Solar energy is one of the most ideal renewable energy sources. In recent years, it has been recognized as one of the most promising sources of energy in our increasingly industrialized society. Although in theory the amount of solar energy far exceeds most, if not all, of the amount of other energy (renewable or non-renewable), the use of such energy presents enormous challenges. Often, solar energy faces many limitations that fully play its role. On the one hand, how to provide an electrical output commensurate with its cost is a challenge. A major aspect of the present invention is to significantly reduce the cost of solar power utilization, making it a cost-effective source of power. One of the most effective ways to convert solar energy into electrical energy is to use solar cells. The device generates photo-generated direct current via a photoelectric effect. Typically such solar cells are electrically connected to each other to form a battery pack for a solar panel or a PV (photovoltaic) panel. PV panels are typically connected in series to provide a higher voltage of -4-201037958 at a reasonable current. This can reduce the loss of the electrical interconnection. Since the power converter used can more efficiently utilize higher voltages, the output of a solar cell or solar panel or even a combination thereof is generally converted into the most efficient power source. Conventional power converters even use MPPT (Maximum Power Tracker) circuitry at their inputs to extract the maximum amount of power from one or more or even a string of connectors. However, the problem with this approach is that since the PV panel typically acts as a current source and when connected in series, the minimum power panel will limit the current through any of the plates. Furthermore, historical solar cells have been fabricated using semiconductors such as 矽 PN junctions. These junctions or diodes convert sunlight into electrical energy. These diodes have a low voltage output characteristic 'usually on the order of 0.6 volts. This battery acts in parallel with the forward diode and acts like a current source. The output current of such batteries can be a function of many structural factors, usually proportional to the amount of sunlight. The low voltage of such solar cells will be difficult to convert into power suitable for powering the power grid. Many diodes are typically connected in series on a photovoltaic panel. For example, one possible configuration may have 36 diodes or plates connected in series to obtain 21.6 volts. In fact, such a board with a bypass diode also has an interconnect loss, so that only 15 volts can be generated at its maximum power point (MPP). For some larger systems with more such boards, even 15 volts is not sufficient to transmit substantially on the wire without loss. In addition, today's typical systems combine multiple plates in series to provide 100 volts to minimize conduction losses between the PV panel and the power converter. However, the problem with the electrical state is to find the appropriate input impedance of the converter to obtain maximum power from such a string of PV panels. Extracting power at the maximum power point is often referred to as MPP tracking. However, some of these systems have some limitations that will be discussed here in 201037958. First, the PV panel can act as a current source. Therefore, the board that produces the minimum current will limit the current through the entire board. In the undesired case, if a poor board produces a relatively small current, it will be reverse biased by the other boards. A reverse diode can be placed at the intersection of each board to limit the power loss in this case and protect the board from reverse breakdown. In the system, at least the following problems have occurred and caused a certain degree of loss in solar energy conversion: A. unevenness between plates B. half-negative weather C. ash or accumulation hinders sunlight D. board damage E. Uneven degradation of the board as time passes. When expensive PV panels are used in series, it can be cumbersome, and the most fragile boards will limit the current flowing from any other board. Disadvantageously, the purpose of the series connection is to obtain a sufficiently high voltage to more efficiently transmit power to the load load, such as a parallel type converter, through the geographical distribution. In addition, in many systems, PV panels can be placed on the roof, such as for housing related equipment. The converter is usually placed at a distance from the roof, such as through a power meter. Therefore, in the embodiment, it is necessary to propose a series connection board and not to generate loss due to the minimum power board or any series-parallel connection. It is also necessary to be able to use different boards without considering the connection structure (series or parallel, etc.). The technology of photoelectric energy conversion is considered to be the biggest limitation of the full effect of solar energy 201037958. An attempt to use a DC/DC converter as a solar energy conversion method along each of the boards of the MPP circuit has been proposed to improve the energy harvest rate when the solar panel is used in series. However, such attempts have led to unacceptable inefficiencies, making this approach impractical. To some extent, these technologies have been missed to consider such issues. For example, in an article by GR Walker, J. Xue, and P. Sernia entitled "PV String Per-Module Maximum Point Enabling Converters," the authors suggest that efficiency losses are inevitable, but the proposed modules still have some 〇 Advantages, although it achieves low efficiency. Similarly, the technique required by the two authors G.R. Walker and P. Sernia entitled "Cascaded DC-DC Converter Connection of photovoltaic Modules" shows that the required technology is always at an unfavorable efficiency. A graph of efficiency and power is even shown in these documents, which shows a full power approaching 91%. Simply put, the costly operation of PV panels through inefficient converters is unacceptable on the market. Another problem that has not been studied is that the huge series of PV panels in series have extremely different output voltages, so that the state of the converter driving the power grid needs to be adjusted over a wide range, resulting in a decrease in efficiency. A further problem is that the input voltage of the converter will not increase or exceed the controllable limit during the period when the converter is not powered to the grid. Or conversely, even if the voltage during this period does not exceed the controllable limit, the final operating voltage will be much lower than the ideal point of converter efficiency. In addition, there are issues with startup and protection that will significantly increase the cost of the entire solar energy conversion method. There are also other secondary factors that affect the solar installation system into the 201037958 balance (BOS). Thus, at least one aspect of the electrical demand for solar energy is to increase the efficiency of the electrical system conversion phase. The present invention just provides the necessary improvement in this regard. SUMMARY OF THE INVENTION As in the field of the invention, the invention includes various aspects that can be combined in different ways. The following description will enumerate various components and illustrate some embodiments of the invention. The components are described in terms of a basic embodiment, however, it should be understood that they can be combined in any manner and in any number to produce other embodiments. The various embodiments and preferred embodiments described are not to be understood as limiting the invention, but are merely illustrative of systems, techniques, and applications. In addition, it should be understood that the present description supports and encompasses all of the various embodiments, systems, techniques, methods, devices, and any number of disclosed elements, with separate elements, and also all of the various in this or any subsequent application. The use of any and all of the various changes and combinations of components. In various embodiments, the present invention discloses various results, systems, and different original exemplary structures that can achieve the objectives of the present invention. The system features alternating photoelectric conversion, high efficiency conversion design, and multi-peak conversion. Some structures can be used in combination with an MPP and even a dual mode power conversion circuit to obtain a stupid power conditioner (PC) component. As described above, such power conditioners can be arbitrarily combined in series or in parallel or in series/parallel connection and designed to enable solar panels to perform their full power output primarily or even for long periods of time. Even different types of boards with different output characteristics can be combined and get the maximum power of each board. In some designs, series series are used to obtain the high voltages useful for electrical transmission. The design of each power modulation 201037958 is to produce its maximum power. In an embodiment, the present invention allows each panel to individually produce its maximum power, thereby enabling more total energy to be harvested throughout the system. The system has an MPP circuit and an energy conversion circuit on each board. These circuits are inexpensive, simple circuits that perform several functions. First, the circuit is designed to extract the maximum power available for each board. Second, the circuit is designed to change the impedance that naturally occurs when combined with other boards in the series. This circuit can also be configured in parallel connected boards or even in a single battery or panel string. The embodiment thus configured achieves a higher voltage output (e.g., 400 volts). In addition, this structure is also easy to control overpressure or other protection, with or without feedback components that control the system to avoid overpressure or other conditions. The additional configuration of a single MPP circuit on the board does not add much to the cost, and in some embodiments can replace the power converter to achieve the same functionality. This circuit can also be incorporated into a PV panel and does not need to be reused in a net junction converter, so this will give significant advantages to the same overall circuit. In the embodiment, a small MPP converter can be used instead of a large converter, which will result in higher energy gain. [Embodiment] [Embodiment] As described above, the present invention discloses various aspects of the aspect that can be used alone and in combination with others. The original idea was that an example of a power conditioner according to the present invention could be used in combination with any of the following principles and circuits: an alternate processing converter (a 11 ernativepr 〇cessc ο nverter ), a dual mode photoelectric converter, an extremely efficient photoelectric converter , multi-peak opto-electrical converters, incorporating a maximum 201037958 power tracker (MPP or MPPT) into the above components, and embodiments including controllable limits such as controllable output voltage, output current, and output power. All of this should be understood in a broad sense and with the embodiment of the display initial applications for implementation. The underlying benefits of all of these aspects are discussed separately and discussed in the following discussion in conjunction with representative primary topology rather than merely based on the above. BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 shows an embodiment of a solar crucible system illustrating the basic principles of solar energy conversion of the present invention. As shown, it includes a solar source (1) that is injected into the photoelectric DC-DC power converter (4), and the power converter (4) supplies the converted output to a photo-DC that is primarily connected to a grid (10). -AC converter (5). It will be appreciated that the solar source (1) may be a solar cell, a solar panel or even a panel string. In any case, the solar source (1) is capable of providing a DC photo-electric output (2). The DC optoelectronic output (2) acts as a DC input to the DC-DC power converter (4). The operation of the DC-DC power converter (4) is controlled according to the performance normally indicated by the converter function control circuit (8). Those skilled in the art will appreciate that the converter function control circuit (8) has a broad meaning and can be a real circuit hardware or firmware or software to achieve the desired control. Similarly, the DC-DC power converter (4) can be considered to represent an optoelectronic DC-DC energy conversion circuit. At this point, hardware circuits are likely to be required, however, it should be understood that the term "circuit" still includes a combination of hardware, firmware, and software. As shown in Figure 1, the various components can be connected to each other. Direct connection is only a way in which various components can respond to each other, i.e., if a component's dry effect can directly or indirectly cause another effect or change. The function of the DC-DC power converter (4) is to convert its output and provide a converted DC photo-electric output (6) as an input to a variety of designed DC-AC converters (5). The DC-AC converter (5) may or may not be included in an embodiment of a solar power system. If included, its function is to complete the conversion of the DC power to a converted DC (7) such as a photovoltaic AC power output (7) that can be used, for example, to connect via a so-called AC power grid interface (9) Power grid (10). Thus, the system can generate a 0 DC photooutput (6) as an input to some types of DC-AC converters (5). The step of converting the input should be understood to include and generate any alternating signal from any DC current signal, even if the signal itself is not perfect or not very stable. As shown in Figures 2 and 6, a single solar source (1) (battery, board or module level) can be used in combination to produce a source of string electrical connections. This combination can be responded to by a series or parallel connection. As shown in FIGS. 2 and 6, a plurality of connections can be formed into a series electrical connection item. A solar 〇 V plate (11) such as an electrical connection is arranged in series. As shown in Figure 2, each such string itself is from a component to a very large combination forming a photovoltaic array (12) or a plurality of combined solar sources. Through a physical or electrical overall layout, several of these cells, plates or strings may be adjacent to one another such that they are exposed to more similar electrical, mechanical, environmental, solar exposure (or non-sun) conditions. . As shown schematically in Figure 2, in the case of large arrays, a high voltage DC-AC solar converter and a three phase high voltage converted AC optoelectronic output must be added. As shown for the combination of electrical series, the output can be combined, so its voltage will increase but their current will not change. Conversely, a combination of electrical parallels may also occur. 2 and 6 illustrate an embodiment of a connection to implement a series combination or series component such as a converted DC optoelectronic output (6) to produce a converted DC optoelectronic output to a DC-AC converter (5). As shown, the converted DC optoelectronic output (6) can be obtained in series, followed by a converted DC optoelectronic output (13) that is supplied as a converted DC optoelectronic input (14) to some types of optoelectronic DC-AC converters. (5) or other loaders. Again, each solar source (1) can be battery, plate, tandem or even array 〇 grade. It will be appreciated that the steps of connecting the converter or its output in parallel and in parallel may also be implemented. As mentioned above, the configurable circuit and system extract more power from the solar source (1). Electrically, the MPP circuit or Maximum Power Tracker (MPPT) can be used to extract more power at the maximum power (MPP) of one or more solar cells, boards or series. Thus, in an embodiment, a solar energy system in accordance with the present invention includes an MPPT control circuit having an energy conversion circuit. A subsequent range limiting circuit can also be included. 〇 Figures 3 and 4 show the maximum power point and the Maximum Power Tracking (MPPT) circuit can be configured to find the best point to extract power from a given board or other solar source (1). As a background, it should be understood that the plates measured in the laboratory have the relationship of voltage and current as shown in Figure 3. The vertical axis is the current in amps. The horizontal axis is the voltage in volts. Fig. 4 shows the case where the power is obtained by using a voltage several times the current. The vertical axis is now power. An example of an MPPT circuit used here is to give the board the proper load resistance or more accurate impedance, and the operating board provides its power peak. It can be seen from the graph that when the board is produced, -12-201037958 is close to 15 volts and 8 amps, and the board has the maximum power under the measurement conditions. This can be determined by the maximum optoelectronic power converter functional control circuit (15), which is part or all of the modality of the converter functional control circuit (8). Thus, the converter or conversion step can achieve the maximum opto-electricity mode of the photovoltaic DC-DC energy conversion or maximum optoelectronic power conversion step. The above can be achieved by the switch and the task cycle switch as described below. Similarly, the system can also perform the steps of the maximum photoelectric power task cycle switch or the maximum photoelectric voltage deterministic task cycle switch.技术 Those skilled in the art will appreciate that there are a variety of circuit configurations that can be used to obtain MPP information. Some can be based on observing short circuit current or open circuit voltage. Other types of schemes can be referred to as disturbance and monitoring (P&0) circuits. This P&0 method can be used in combination with a technique called "hill climb" to obtain MPP. As explained below, the MPP of the adjacent source for each source, or the entire series, can be individually determined to operate to achieve the best operation. Thus, embodiments of the combined system may utilize a dedicated maximum opto-electric power point converter functional control circuit (16) dedicated to the board (understood to include any source level). Whether or not it is a single configuration, the analog circuit can be configured in the p&0 method to generate a ripple voltage on the board. The board voltage and its first derivative (V,)' as well as the board power and its first derivative (P,) can be obtained using a simple analog circuit. Use two derivatives and simple logic to adjust the load on the board as follows: -13- 201037958

出回應(即使它不是V*I倍增函數的精確的計算結果)。當 然這可以是V*I類型對一些功率參數的計算,且該系統將 以某種方式作用以提高或降低其自身,以基本移動更接近 於並且最終實現在ΜΡΡ水準上的運轉運轉。透過產生功率 ® 以及實現計算光電倍增功率參數的步驟,該系統可對該參 數作出回應以獲得預期結果。 在串聯功率調節器(17)等的實施例中,透過每個PC 輸出的電流可能相同,但每個PC的輸出電壓將於該板產生 的功率量成正比。參考以下實施例以進一步解釋此類實施 例的功能。硏究圖6的電路並將其與簡單串聯連接的板相 比(注意簡單串聯可能具有交叉的反向二極體)。首先,假 設4塊面板串聯,每塊板產生1〇〇伏和1安供給,那麽提 -14- 201037958 供給轉換器的輸入設置將是400伏。用任何方法都將提供 400瓦的輸出。現在考慮一塊板產生1〇〇伏和〇.8安的結果 (模擬半陰的環境:較少光可簡單理解爲較少電流)。串聯 的話,〇·8安的電流將透過每塊板,獲得400X0.8 = 320瓦 的總功率。首先’當每塊板均在其自身MPP上產出時總功 率可以是380瓦。並且由於每個功率調節器隨後仍然串聯 連接’很顯然從它們流出的電流必須相等。但電壓可借助 每個P C的已知功率進行如下計算獲得: 3V + 0.8V = 400伏,其中V是每塊全功率板的電壓。 因而’可以看出在這個實施例中,三塊板可獲得105.3 伏,每塊板可獲得84.2伏。 此外,在圖6中,能夠理解,在一些實施例中,進串 列單個功率控制可獲得額外的益處。在這樣的實施例中, 功率塊被視爲在每塊板上具有功率轉換器和MPP的一組 PV板。這樣它們將根據需求調整它們的輸出,以始終維持 各自和每個功率塊輸出的最大功率。如果調整成配合這種 功率塊串列中使用,該系統甚至可能藉作用於其輸出之變 化電壓操作。 第二個實例的MPP的運轉顯示的這類結構的優點。該 實例顯示當一塊板處於陰影處時它僅能產生0.5安的電 流。對於串聯連接的串列來說,產生1安的三塊板可徹底 反向偏壓板,產生0.5安導向反向二極體的電流。還可能 僅僅存在總共300瓦的來自三塊板的功率。再次對於發明 的實施例電路來說,每塊PC將產生MPP總量350瓦。這 -15- 201037958 時電壓計算將是: 3V + 0.5V = 400 伏 在這個實例中,三塊板將獲得Π4.2伏的電壓,剩下 一塊可獲得一半,或57.1伏的電壓。輸出電壓能夠被視爲 與PV板輸出功率成正比,因而獲得較好結果。 有若干基礎實例來圖示一些優點。目前,在真實的PV 串列中,可有許多串聯的PV板。通常,它們都無法獲得完 全相同的功率。因而,許多板將被偏壓回,且大多數將產 ® 生小於它們單個的MPP。這可透過本發明的實施例來克 月艮。圖6顯示可從該面板串列中獲得功率並供給電力網的 功率轉換器。如以下所討論,這種結構可能透過設置運轉 運轉界限可需要電壓限制和/或保護。 功率調節器(17)可以配置來從PC板提取最大功率。 根據本發明的實施例,這可透過功率調節器(17)、光電 DC-DC功率轉換器(4)或轉換器功能性控制回路(8)提 供的阻抗轉換容量(impedance transformation capability) Ο 得以實現。其可根據需要轉換單個或組功率傳輸以維持 ΜΡΡ。因而該系統將導致每塊板的電壓不停變化,同時實 現每塊板的最大輸出。根據系統的拓撲,它可獲得恒定或 常規電流,因此串聯串列可處於最大功率。在實施例中, 本發明可配置以提高或減少每塊板的負載阻抗,如果需要 甚至可提供固定電壓。 如上所討論,光電DC-DC功率轉換的光電阻抗轉換模 態可由光電阻抗轉換功率轉換控制回路完成。圖5Α和5Β -16- 201037958 顯示配電(switching)或開關模式(switchmode)的光電 阻抗轉換的光電DC-DC功率轉換器的兩個實施例。可以理 解’這裏的開關可以被轉換器功能性控制回路(contr〇l circuitry) (8)控制進行任務循環配電,即在週期性(可以 恒定或不同的週期)的時間點上配電以實現多種目的。這 種配電可以多種方式進行。從一種模式至另一種的配電方 法有許多。例如,如果設置了最小脈衝寬度,那麼可透過 如下將討論的脈衝模式(burstmode)進一步減小能量或改 變阻抗。如果最小任務循環(duty cycle)設置爲2%,還 可用2%任務循環的偶發脈衝串列以及假定的〗〇%的脈衝串 列任務循環獲得0.2%的能量傳遞。這裏的大部分可透過頻 繁改變配電或不同開關的其他控制來實現。因而實施例可 提供開關頻繁改變配電的光電功率轉換控制回路(switch frequency alteration switching photovoltaic power conversion control circuitry)。在轉換期間實現高效的同 時還提供了從一個模式至另一個的平穩轉換的可能性。 配電的目的可包括如上討論的最大功率點運轉以及如 下將討論的多種模態。一部分這些模態是附屬的,使得在 部分時間點上、在部分功率狀態時一個將優先於一個或另 一個,或根據部分功率參數實現多種模態的運轉。此外, 一部分這些模態還將隨後進行討論。然而,在阻抗轉換的 過程中可以是光電阻抗轉換任務循環配電,且可由光電阻 抗轉換任務循環開關控制回路(可理解爲包括硬體、固件、 軟體及其任意的組合物)進串列控制。 -17- 201037958 參看圖5A和5B的兩個例子示出的特定實施例,可以 理解光電DC-DC功率轉換器(4)可以運轉來提高或降低 光電阻抗。由於一個或另一個將在任意的時間點上出現, 甚至這種運轉是隨著時間改變而改變的,因此這兩種變換 模式的運轉將是專用的。同樣地,實施例可包括光電阻抗 增大的光電DC-DC功率轉換回路(19)和光電阻抗減小的 光電DC-DC功率轉換回路(20)。圖5A和5B顯示兩個這 種例子,其中可以認爲光電DC-DC功率轉換器(4)的第 Ο 一部分以一種方式(圖5A上部和圖5B下部)作用以及光 電DC-DC功率轉換器(4)的另一部分以另一種方式(圖 5A下部和圖5B上部)作用。因而,可以看出光電DC-DC 功率轉換器(4)的運轉模式可以是相反的,其中一種實現 一種效果而另一種實現相反的效果。系統的實施例提供了 光電DC-DC功率轉換器的至少一種光電阻抗增大模態以及 光電DC_DC功率轉換器的至少一種光電阻抗減小模態。如 圖5A和5B的兩個實施例所示,這兩種模態可出現在一種 〇 W 光電DC-DC功率轉換器(4)中,因此光電DC-DC功率轉 換器(4)可完成光電負載阻抗增大和光電負載阻抗減小的 步驟。這種部件還可以是分離的,因此在交替運轉中,一 個運轉而另一個不運轉反之亦然。還可以是基本分離的’ 因此對於功率轉換無意義週期來說實際上或看上去是在相 同的時間框內運轉的。因而該系統包括基本分離的阻抗轉 換光電功率轉換控制回路。借助於功率調節器(17)結構 和設計,該系統可進行配電或實現其他性能,如果適當的 -18- 201037958 話,還可提供實現預期效果的控制回路。 再參看圖5A和5B示出的實施例,能夠看出一些實施 例使用由光電開關控制回路(23 )控制的一個或多個開關, 因而功率調節器(17)可以是開關模式特徵的。在示出的 實施例中,這些開關是指定的T1-T4和Τ21-24»在一些實 施例中,這些開關可以是半導體開關,且它們有助於降低 損耗和提高效率。此外,開關和連接可配置來獲得一個或 多個光電功率串聯開關部件(24)和一個或多個光電功率 〇 並聯開關部件(25 )。可以理解,光電功率串聯開關部件(24 ) 可提供一個或多個光電功率傳輸中斷(中斷的動作)的位 置,光電功率並聯開關部件(25)可提供一個或多個光電 功率傳輸分流(分流的動作)至地面、另一個功率通路等 的位置。 如圓5A和5B所示,實施例可包括不止一個開關、不 止一個串聯和並聯開關’而是數對串聯通路和分流通路半 導體(或其他)開關。因而,中斷和分流可發生在至少裏 ® 那個分離的半導體位置上。顯然,這些例子配置來更簡單 地示出配電、中斷、分流和組合的各種槪念,然而,可以 理解還可以有更複雜的結構。在許多回路方面,可設置一 些設計來避免實現相同的效果,這當然也落在本發明的範 圍中。 從之前討論的運轉模式(即增大或交替地減小光電負 載阻抗的內容)可以理解:根據本發明實施例的系統可具 有作爲多峰光電DC-DC功率轉換器的光電DC-DC功率轉 -19- 201037958 換器(4),由於它具有多於一種的運轉模式因此由多峰轉 換器功能性控制回路(26)控制。這些模式包括但不限於 光電阻抗增大和光電阻抗減小,以下討論若干其他模式。 通常來說’多峰活動包括至少在任意點上出現僅僅一種模 式的轉換的步驟。無論預期的輸出量如何,也不會再相同 步驟中增大及減小阻抗或其他因素。僅使用轉換的單個方 法,或者單數積分。 因而,功率調節器(17)可提供至少一種第一模態和 Ο 第二模態的光電DC-DC功率轉換電路、DC-DC功率轉換器 或DC-DC功率轉換。此外,在增大或減小光電負載阻抗的 MPP上下文中可以理解,多峰的光電DC-DC功率轉換器或 多峰轉換器功能性控制電路(26)可響應一種或多種光電 功率條件,諸如V”倍增因數、電壓水準、電流水準或一 些其他信號指示或計算設置點。在如此提供多於一種模式 的轉換運轉方式的性能(甚至不必同時使用)中,或在提 供改變運轉模式的性能中,該系統完成了多峰地將DC光 Ο W 電輸入轉換成經轉換的光電DC輸出的步驟。類似地,透 過提供控制多於一種的轉換運轉方式生效(又,甚至不必 同時使用)的性能,或對運轉方式的控制,該系統可完成 多峰地控制光電DC-DC功率轉換器(4)的運轉。 實施例可包括兩個或更多地運轉方式,因而被認爲是 雙模式功率轉換電路或雙模式轉換器。該電路的雙模性能 體現在具有顯著的益處,另一個區別將是大多數DC/DC轉 換器通常意在產生未經調整的源以及產生經調整的輸出。 -20- 201037958 在本發明中,將至DC/DC轉換器的輸入調整成PV板的 MPP。取自PV板的功率將被轉換輸出連接中需要的任意阻 抗’以在不考慮輸出的同時滿足輸入MPP需求,在阻抗被 改變使得輸出電壓低於輸入電壓的情況中,將驅使T3處於 連續導電狀態,T4處於非導電狀態,T1和T2在開關模式 任務循環狀態中運轉。這種任務循環的運轉是同步的,由 於電晶體T2可以是與T1 (反向任務循環)同步的開關。 T2可以是較低RDS(ON)的 FET,具有較該位置上的二極 Ο 體更小的損耗。透過同步運轉,該電路可具有如下之極高 的效率。該電路存在的問題是電流穿過額外的電晶體T3。 但該電晶體未通電時具有較低的損耗。顯然,類似的運轉 可獲得圖5B示出的實施例。 圖5A示出的電路的第二種模式包括需要改變阻抗以 使輸出電壓高於輸入電壓的情況。現在,T1可被轉換爲連 續導電狀態。T2可是非導電的。現在,電晶體T3和T4以 開關模式控制。大家可以看出這種想法適用。首先,所有 〇 開關是具有較低接通狀態損失的電晶體。其次,附加部分 (boost section)高效率地運轉,由於電晶體T1的接通狀 態損失中的雙模性能出現額外的損失。該電路還可利用節 省尺寸、空間和成本的公共電感器L1。此外,熟於本技藝 人士可以理解能使用類似的運轉來實現圖5B顯示的實施 例。 有意思的以及將在以下詳細討論的是,在現有效率有 時低於91 %的同時,該電路能實現預定的需求,且能獲得 -21- 201037958 超過98%的運轉效率以及甚至高達99.2%的效率水準《當 與太陽板或太陽板串列相連接時,這種效率差異將非常重 要。當然,與許多類的DC/DC轉換器相類似的隔離和非隔 離的阻抗轉換可用於本發明的其他揭示揭示態樣中,以及 大多數任意DC/DC轉換器拓撲可用於該功能中,由此包括 在本發明內。 如上簡述的,存在運轉的交替方式,系統可在根據參 數或其他顯示或計算的不同模式之間波動(以及獲得波動 〇 轉換模式)。在一種模式或另一種基本是專用地啓動的實施 例中,功率調節器(17)或其他系統部件可提供交替模式 的光電功率轉換器功能性控制(2 7 )。它是在至少一些時候 的模式之間的專用開關。這些模式可以是轉換模式,因此 系統可提供給產生太陽能功率的波動方法。如上所示,這 些模式可以是相反或相反的模態、基本分離或其他的模式。 在專用地控制特定運轉模式中,系統禁止出現無使用 模式。這是很重要的,例如,可實現如下之更高的效率水 〇 準等。參看圖5A和5B中的光電阻抗轉換顯示的實施例, 可以理解本發明的實施例是如何禁止光電DC-DC功率轉換 模式或至少某些時候的運轉,因而系統可提供無效的交替 模式的光電功率轉換控制電路(28)。如參看以上MPP的 開關運轉中所討論的,一個或多個開關,諸如光電功率並 聯開關部件(25),一個光電功率串聯開關部件(24)或其 他在運轉中可被禁用。這將實現比較運轉模式的性能,或 者更重要地,可實現之前認爲不可能實現的高效率的運 -22- 201037958 轉。因而,實施例可提供光電無效模式的轉換器功 制電路。 具有優越的運轉性能是本發明實施例的性能, 太陽能源或板能適應不同的運轉條件。如圖7A和 示,最大功率點的運轉電壓將根據太陽能源是否處 或低溫條件而不同。透過允許MPP與任意電壓限制 阻抗轉換相適應,根據本發明的實施例提供擴展了 性能。轉換器實際上是全光電溫度電壓運轉範圍內 O DC-DC功率轉換器,借此能在與低溫運轉時的MPP 的MPP電壓以及在與高溫運轉時的MPP同樣低的 壓時運轉。因而,從圖7A和7B可以看出,系統可 陽能源開路電路電壓決定性配電的光電功率轉換控 和太陽能源最大功率點熱電壓決定性的光電功率轉 電路。可以實現在全光電溫度電壓運轉範圍中的轉 可透過適當運轉開關任務循環來實現,因而系統提 陽能源開路電路電壓決定性任務循環配電和太陽能 〇 w 率點熱電壓決定性的任務循環配電(switching )。 此外,觀察如極端條件的熱及冷電壓,類似地 解系統是如何接受不同的日射量的,因而該系統具 日射變化的光電轉化能控制電路,無論板是否部 擋,甚至與相鄰板相對都能提取出MPP。系統及其 環配電可與日射量相適應,因此轉換的步驟可根據 的變化而適宜性轉換。這在新技術板諸如碲化鎘太 中尤爲顯著,尤其是當組合來自具有較大運轉電壓 能性控 即各種 7B所 於高溫 無關的 的板的 的光電 同樣高 MPP電 提供太 制電路 換控制 換。這 供了太 最大功 可以理 有適應 分被遮 任務循 曰射量 陽能板 的碲化 -23- 201037958 鎘太陽能面板串列的輸出時。 如早則之’非常重要的是轉換器運轉的效率水準。這 可定義爲在將來自之前轉換的功率轉換後輸出的功率。用 開關模式運轉的電晶體開關來實現一部分效率收益,然 而’在這點上拓撲更爲重要。特別是透過如上之開關運轉 等,系統可遠超過之前可能設想的效率水準。它甚至可獲 得基本功率同構的光電DC-DC功率轉換,基本沒有將功率 轉換爲熱量而是轉換爲電能,獲得高達大約99.2%的效率。 ^ 這可利用基本公理同構的光電轉換器功能和基本功率同構 的光電阻抗轉換器,以及透過控制運轉開關來實現,因此 如上前述限制了損失。這種運轉可獲得97、97.5、98、98.5 甚至高達99.2的水準或基本上是電線傳輸損失的效率(認 爲還可能更高)。 有助於實現這種效率的一個態樣是在轉換期間存儲的 最小量的能量。如圖5A和5B所示,該實施例可包括並聯 電容和串聯電感。這可用來存儲至少數次在轉換運轉期間 ® 的能量。可發現全能量轉換是無法實現的,對於獲得的預 期結果來說轉換量是必需的。因而實施例可起到低能存儲 光電DC-DC功率轉換器以及甚至部分能量存儲光電DC-DC 功率轉換器的作用。在輸入電壓和輸出電壓幾乎相等以& 轉換器實現統一轉換的情況中,能量存儲幾乎沒有發生改 變,因此系統出現具有基本恒定能量存儲的光電DC-DC功 率轉換器的實施例。任務循環能量存儲可與轉換中 電壓成正比(線性、連續或不是)。在電感器中的能量存胃 -24- 201037958 可與一個或多個開關的任務循環成正比。部分效率被認爲 是運轉期間開關保持靜態即打開或閉合的結果。因而實施 例提供了靜態開關交替模式的光電功率轉換控制電路,以 及類似的,靜態開關轉換。還提供了分級開關部件控制電 路。 在運轉的可變任務循環模式中可以控制開關,因而改 變配電頻率以實現預期效果。轉換器功能性控制電路(8) 可起到光電任務循環開關控制電路的作用。任務循環運轉 ® 和配電可實現各種結果,從起到光電阻抗轉換任務循環配 電作用至其他運轉。這些中的一部分甚至是與光電DC-DC 功率轉換器(4)的主要目的的轉換態樣相違背的。 雖然在理論上或日常運轉中上述電路表面良好,但對 具有實際功能的系統來說還有額外的需求。例如前述雙模 電路將產生無窮輸出電壓,如果不存在負載的話。這種情 況在實際中經常發生。考慮太陽首先照射到具有功率調節 器(17)的PV面板串列上的早晨的情況。這時沒有電力網 〇 連接,轉換器部分不抽運任何功率。這種情況中,功率調 器(17)在實際運轉中將提高其輸出電壓直至轉換器損 壞。該轉換器在其輸入增加額外功率轉換部件上具有過壓 保護,或功率調節器可簡單地具有其自身的內部輸出電壓 限制。例如如果每個功率調節器(1 7 )盡可產生1 00伏的 最大電壓,那麼串聯的10塊PC的一串列的最大輸出電壓 將是1 0 0 0伏。該輸出電壓限制將使網結轉換器不那麼複雜 及昂貴,以及圖7A中顯示如重置過壓限制的電壓限制。因 -25- 201037958 而實施例可表示出最大電壓決定性配電光電功率轉換控制 電路和最大光電電壓決定性任務循環配電(圖7A中用重置 過壓限制顯示)。它可以是特定的轉換器。 最大輸出電流限制也可能非常有用,在圖7A中其以被 顯示爲預置過流限制。這不那麼簡明且涉及PV板的性能。 如果PV板無法受到足夠光照射時其輸出電壓將降低但其 輸出電流可以不增加。優點在於僅允許額外電流存在小的 變化餘地。例如,具有1 〇〇瓦最大電壓限制的相同的1 00 Ο 瓦的板可具有2安的電流限制,而不需要限制其預期用 途。這還可極大簡化隨後的網結轉換器狀態。考慮在大型 設備中的轉換器情況,該大型設備需要用來保護的前端分 流斷路器。如果PC的輸出到達100安,斷路器將解決不實 用的電流。這種情況不會發生在非PC環境中,如一個簡單 的PV面板串列可由於斷路器電路而輕易地被損壞。僅僅 PC需要這種電流限制電路以及這也可透過任務循環或更 精確地開關運轉控制來簡單地實現。一旦電流限制包括在 〇 W 另一個中,將實現BOS節省。現在串聯PC串列的互聯的 電線尺寸均限制爲僅能負載最大電流限制的尺寸。這裏的 實施例可表示最大光電反相器電流轉換器功能性控制電 路、反相器最大電流決定性配電、光電反相器最大電流決 定性任務循環開關控制電路和光電反相器最大電流決定性 任務循環配電等。 繼續討論另一個系統的問題。在太陽能設備中,還可 能出現極端情況,即板或板的領域接收到多於全日的能 -26- 201037958 量。這發生在存在耐火情況以及雲或其他反射面時。PV源 在數分鐘內將產生大約1.5倍的額定功率。網結反相器部 分必須能在較高功率時運轉(增加成本)或必須某種程度 上避免這種功率。PC的功率限制是最有效的解決這個問題 的方法。通常,一些其他元件的保護可由轉換器完成。甚 至是後端或下游的部件諸如反相器,因此轉換器功能性控 制電路(8 )起到光電DC-DC功率轉換的光電反相器保護 模態作用,並被認爲是光電反相器保護轉換器功能性控制 D 電路。在保護之外,理想的反相器或其他運轉條件可由轉 換器實現,因而實施例可包括光電反相器運轉條件的轉換 器功能性控制電路。這可透過某種方式進串列簡單調整, 諸如透過光電反相器或後端部件調整模態或光電反相器或 後端部件調整轉換器功能性控制電路。還有具有較小輸出 電壓(處於允許的輸出電壓範圍內)的實施例。 如圖7A、7B和9所示,可如此設置邊界條件,諸如 過流限制和過壓限制。因而轉換器和/或其控制電路起到光 D 電邊界條件轉換器功能性控制電路的作用,實現光電 DC-DC功率轉換的光電邊界條件模態,以及可完成控制光 電DC-DC轉換器的光電邊界條件的步驟。 另一個模式的運轉是獲得與某些態樣成一定比例(廣 義的)的値。例如,產生與電流成一定比例的電壓以提供 平穩啓動性能等的優點。因而可配置成在將DC輸入轉換 成DC輸出的步驟期間可控制與至少一些次數的光電輸出 電流成一定比例的最大光電輸出電壓的實施例。通常,還 -27- 201037958 可提供軟轉換光電功率轉換控制電路。該系統可包括任務 循環控制或開關運轉’引導它們來實現最大電壓輸出和電 流輸出等之間的一種或多種比例。此外’不僅僅可組合上 述的任意結構,而且每個均可以附屬的方式進串列’因此 一種模態的考慮相對於另一種模態來說是次要的。 它們可透過簡單地改變開關影響的任務循環或開關實 現。它們可根據臨限値完成’並提供觸發臨限値的可選模 式、臨限値決定性的、臨限値啓動或臨限値滅活配電的光 Ο 電功率轉換控制電路。諸如當接近一種模式改變水準運轉 時可實現脈衝串列方式的運轉’且這時可等分頻率’相對 模式均可交替,以及可降低水準如改變回到初期。這也可 以是暫態的。脈衝串列模式配電的光電功率轉換控制電路 和脈衝串列模式配電可以這種方式完成,還有暫態相對模 式的光電任務循環開關控制電路和暫態建立相對配電模式 的步驟均可以這種方式完成。 如上前述,PC和光電DC-DC功率轉換器(4)可操縱 〇 w 單塊板。它們可附在板、框上或與之分離。實施例具有與 此類板物理集成的轉換器,以他們作爲最終裝置的附屬單 元形式存在。這是非常理想的,諸如當分離的太陽能源以 及相鄰的太陽能源具有獨立的運轉條件以適應不同的日射 量、條件或其他情況時。每塊板等實現它自身的MPP,並 與串列上的其他板等受到相同的保護。V, positive number P' positive number increases MPP V' positive number P' negative number decreases MPP V' negative number P' positive number decreases MPP

Typically, the power conditioner (17) can include a power calculation loop (solid or software) (21), which can even be a photomultiplier synthesis loop (22). These loops can act to influence the result or respond to a component similar to the power indication (even if it is not an accurate calculation of the V*I multiplication function). Of course this can be a calculation of some power parameters of the V*I type, and the system will act in some way to raise or lower itself, with the basic movement being closer to and ultimately achieving operational operation at a level. By generating power ® and implementing the steps of calculating the photomultiplier power parameter, the system can respond to this parameter to obtain the desired result. In an embodiment of a series power regulator (17) or the like, the current output through each PC may be the same, but the output voltage of each PC will be proportional to the amount of power generated by the board. The following examples are referred to to further explain the functions of such embodiments. Consider the circuit of Figure 6 and compare it to a simple series connected plate (note that a simple series may have crossed reversed diodes). First, assuming that four panels are connected in series, each panel producing 1 volt and 1 amp supply, then the input setting for the -14-201037958 supply converter will be 400 volts. Any method will provide an output of 400 watts. Now consider the result of a plate producing 1 〇〇 and 〇8 amps (simulating a semi-shade environment: less light can be simply understood as less current). In series, 〇·8 amps of current will pass through each board, yielding a total power of 400X0.8 = 320 watts. First, the total power can be 380 watts when each board is produced on its own MPP. And since each power regulator is then still connected in series, it is clear that the current flowing from them must be equal. However, the voltage can be calculated by the known power of each P C as follows: 3V + 0.8V = 400 volts, where V is the voltage of each full power board. Thus, it can be seen that in this embodiment, three plates can obtain 105.3 volts and each plate can obtain 84.2 volts. Moreover, in Figure 6, it can be appreciated that in some embodiments, a series of individual power controls can provide additional benefits. In such an embodiment, the power block is considered to be a set of PV panels with power converters and MPPs on each board. This way they will adjust their output as needed to maintain the maximum power output for each and every power block. If used in conjunction with such a power block string, the system may even operate with varying voltages applied to its output. The operation of the MPP of the second example shows the advantages of this type of structure. This example shows that when a board is in the shadow it can only generate a current of 0.5 amps. For a series connected series, three plates of 1 amp are produced to completely reverse bias the plate, producing a current of 0.5 amps directed to the reverse diode. It is also possible that there is only a total of 300 watts of power from three boards. Again for the inventive embodiment circuit, each PC will produce a total of 350 watts of MPP. The voltage calculation for this -15-201037958 would be: 3V + 0.5V = 400 volts In this example, the three boards will get Π4.2 volts and the remaining one will get half, or 57.1 volts. The output voltage can be considered to be proportional to the PV panel output power, resulting in better results. There are several basic examples to illustrate some of the advantages. Currently, there are many PV panels in series in a real PV string. Often, they are not able to get the same power. As a result, many boards will be biased back, and most will produce less than their individual MPP. This can be achieved by the embodiment of the present invention. Figure 6 shows a power converter that can draw power from the panel string and supply it to the power grid. As discussed below, such a configuration may require voltage limiting and/or protection by setting operational operating limits. The power regulator (17) can be configured to extract maximum power from the PC board. According to an embodiment of the invention, this can be achieved by an impedance conversion capability provided by the power conditioner (17), the opto-electronic DC-DC power converter (4) or the converter functional control loop (8). . It can convert single or group power transfers as needed to maintain ΜΡΡ. Thus the system will cause the voltage of each board to constantly change while achieving the maximum output of each board. Depending on the topology of the system, it can achieve constant or regular current, so the series string can be at maximum power. In an embodiment, the invention can be configured to increase or decrease the load impedance of each board, even providing a fixed voltage if desired. As discussed above, the photoelectric impedance conversion mode of the photoelectric DC-DC power conversion can be accomplished by a photoelectric impedance conversion power conversion control loop. Figures 5A and 5A - 16 - 201037958 Two embodiments of a photoelectric DC-DC power converter showing photoelectric impedance conversion of a switching or switch mode. It can be understood that the switch here can be controlled by the converter's functional control loop (8) to perform duty cycle distribution, that is, to distribute power at a time point (which can be constant or different) for various purposes. . This type of distribution can be done in a variety of ways. There are many ways to distribute power from one mode to another. For example, if the minimum pulse width is set, the energy can be further reduced or the impedance can be changed by the burst mode discussed below. If the minimum duty cycle is set to 2%, 0.2% energy transfer can also be obtained with the 2% duty cycle burst sequence and the assumed 〇% pulse train task cycle. Much of this can be achieved by frequently changing the power distribution or other controls of different switches. Thus, embodiments can provide switch frequency alteration switching photovoltaic power conversion control circuitry. Efficient implementation during conversion also provides the possibility of a smooth transition from one mode to another. The purpose of power distribution may include maximum power point operation as discussed above and various modes as discussed below. A portion of these modalities are affixed such that at some point in time, in a partial power state one will take precedence over one or the other, or multiple modalities may be operated based on partial power parameters. In addition, some of these modalities will be discussed later. However, in the process of impedance conversion, the photoelectric impedance conversion task can be cyclically distributed, and can be controlled by a photo-electrical impedance conversion task cycle switch control loop (which can be understood to include hardware, firmware, software, and any combination thereof). -17- 201037958 Referring to the particular embodiment illustrated by the two examples of Figures 5A and 5B, it will be appreciated that the optoelectronic DC-DC power converter (4) can operate to increase or decrease the photoimpedance. Since one or the other will appear at any point in time, even if the operation changes over time, the operation of the two transformation modes will be dedicated. Likewise, embodiments may include an opto-electronic impedance-increasing opto-electronic DC-DC power conversion loop (19) and a photo-impedance-reduced opto-electronic DC-DC power conversion loop (20). Figures 5A and 5B show two such examples in which the third portion of the optoelectronic DC-DC power converter (4) can be considered to function in one manner (upper portion of Figure 5A and lower portion of Figure 5B) and optoelectronic DC-DC power converter. The other part of (4) acts in another way (lower part of Fig. 5A and upper part of Fig. 5B). Thus, it can be seen that the mode of operation of the optoelectronic DC-DC power converter (4) can be reversed, with one achieving one effect and the other achieving the opposite effect. Embodiments of the system provide at least one opto-electronic impedance increasing mode of the optoelectronic DC-DC power converter and at least one opto-electronic impedance reducing mode of the optoelectronic DC-DC power converter. As shown in the two embodiments of Figures 5A and 5B, the two modes can appear in a 〇W photoelectric DC-DC power converter (4), so the photoelectric DC-DC power converter (4) can complete the photoelectric The step of increasing the load impedance and reducing the photoelectric load impedance. Such components can also be separate so that in alternate operation one runs and the other does not. It can also be substantially separate' so it actually or appears to be operating in the same time frame for a power conversion meaningless cycle. The system thus includes a substantially separate impedance-switching opto-electric power conversion control loop. Thanks to the structure and design of the power conditioner (17), the system can be used for power distribution or other performance, and if appropriate -18- 201037958, a control loop can be provided to achieve the desired results. Referring again to the embodiment illustrated in Figures 5A and 5B, it can be seen that some embodiments use one or more switches controlled by a photoelectric switch control loop (23) such that the power regulator (17) can be switched mode features. In the illustrated embodiment, these switches are designated T1-T4 and Τ21-24». In some embodiments, these switches may be semiconductor switches and they help to reduce losses and improve efficiency. Additionally, the switches and connections can be configured to obtain one or more optoelectronic power series switching components (24) and one or more optoelectronic power 并联 parallel switching components (25). It will be appreciated that the opto-electric power series switching component (24) may provide one or more positions of the opto-electric power transmission interruption (interrupted action), and the opto-electric power parallel switching component (25) may provide one or more opto-electric power transmission shunts (split Action) to the ground, another power path, etc. As shown by circles 5A and 5B, embodiments may include more than one switch, more than one series and parallel switch', but a series of series and shunt path semiconductor (or other) switches. Thus, interruptions and shunts can occur at least in the separate semiconductor location. Obviously, these examples are configured to more simply illustrate the various complications of power distribution, interruption, shunting, and combination, however, it can be appreciated that there may be more complex structures. In many loops, some designs can be provided to avoid the same effect, which of course falls within the scope of the present invention. It will be understood from the previously discussed mode of operation (i.e., increasing or alternately reducing the optoelectronic load impedance) that a system in accordance with an embodiment of the invention may have an opto-electronic DC-DC power transfer as a multi-peak optoelectronic DC-DC power converter. -19- 201037958 The converter (4) is controlled by the multi-peak converter functional control loop (26) because it has more than one mode of operation. These modes include, but are not limited to, photoelectric impedance increase and photo-resistance reduction, and several other modes are discussed below. In general, multi-peak activity includes the step of converting only one mode at least at any point. Regardless of the expected output, the impedance or other factors will not increase or decrease in the same step. Use only a single method of conversion, or singular integration. Thus, the power conditioner (17) can provide at least one first modal and Ο second mode optoelectronic DC-DC power conversion circuit, DC-DC power converter or DC-DC power conversion. Furthermore, it is understood in the context of an MPP that increases or decreases the photoelectric load impedance that a multimodal opto-DC-DC power converter or multi-peak converter functional control circuit (26) can be responsive to one or more optoelectronic power conditions, such as V" multiplication factor, voltage level, current level or some other signal indicating or calculating set point. In the performance of the switching mode of operation that provides more than one mode (not even simultaneously), or in providing performance that changes the mode of operation The system completes the multi-peak conversion of the DC optical input into a converted optical DC output. Similarly, performance is achieved by providing more than one conversion mode of operation (again, not even simultaneously) , or control of the mode of operation, the system can perform multi-peak control of the operation of the optoelectronic DC-DC power converter (4). Embodiments may include two or more modes of operation and are therefore considered to be dual mode power Conversion circuit or dual mode converter. The dual mode performance of this circuit is reflected in significant benefits, another difference will be most DC/DC conversion It is generally intended to produce an unadjusted source and produce an adjusted output. -20- 201037958 In the present invention, the input to the DC/DC converter is adjusted to the MPP of the PV panel. The power taken from the PV panel will be converted. Any impedance required in the output connection 'to meet the input MPP requirements without considering the output. In the case where the impedance is changed such that the output voltage is lower than the input voltage, T3 will be driven in a continuous conduction state, and T4 is in a non-conducting state, T1 And T2 operate in the switch mode task cycle state. The operation of this task cycle is synchronous, since transistor T2 can be a switch synchronized with T1 (reverse task cycle). T2 can be a lower RDS(ON) FET. It has a smaller loss than the two-pole body at this position. Through synchronous operation, the circuit can have extremely high efficiency as follows. The circuit has a problem that current passes through the additional transistor T3. There is a lower loss when not energized. Obviously, a similar operation can achieve the embodiment shown in Figure 5B. The second mode of the circuit shown in Figure 5A includes the need to change the impedance to make the output voltage In the case of input voltage, T1 can now be converted to a continuous conduction state. T2 can be non-conductive. Now, transistors T3 and T4 are controlled in switch mode. You can see that this idea applies. First, all switches are A transistor with a lower on-state loss. Second, the boost section operates efficiently, with additional losses due to dual mode performance in the on-state loss of transistor T1. The circuit can also be utilized to save size. , Space and Cost Common Inductor L1. Further, it will be understood by those skilled in the art that similar operations can be used to implement the embodiment shown in Figure 5B. Interestingly and as will be discussed in detail below, current efficiency is sometimes low. At 91% of the time, the circuit can meet the predetermined requirements, and can achieve -98% of the operating efficiency of -21,037,958 and even an efficiency level of up to 99.2%. When connected to a solar panel or a solar panel, this The difference in efficiency will be very important. Of course, isolated and non-isolated impedance conversions similar to many types of DC/DC converters can be used in other disclosed aspects of the present invention, and most arbitrary DC/DC converter topologies can be used in this function, by This is included in the present invention. As briefly mentioned above, there is an alternating manner of operation, and the system can fluctuate between different modes based on parameters or other displays or calculations (and obtain a fluctuation 〇 conversion mode). In one mode or another embodiment that is essentially dedicated to startup, the power conditioner (17) or other system components can provide an alternate mode of optoelectronic power converter functionality control (27). It is a dedicated switch between modes at least some time. These modes can be conversion modes, so the system can provide a method of fluctuation that produces solar power. As indicated above, these modes can be opposite or opposite modes, substantially separate or other modes. In the specific control of the specific operation mode, the system prohibits the useless mode. This is important, for example, to achieve the following higher efficiency standards. Referring to the embodiment of the photoelectric impedance conversion display of Figures 5A and 5B, it will be appreciated how embodiments of the present invention inhibit photoelectric DC-DC power conversion mode or at least some of the time, and thus the system can provide an ineffective alternating mode of photovoltaic Power conversion control circuit (28). As discussed with reference to the switching operation of the MPP above, one or more switches, such as opto-electric power parallel switching components (25), a photovoltaic power series switching component (24) or the like, may be disabled during operation. This will achieve the performance of the comparative operational mode or, more importantly, the efficient operation of the -22-201037958 that was previously considered impossible. Thus, embodiments can provide a converter power circuit in a photo-inactive mode. Having superior performance is a property of embodiments of the present invention, and the solar source or panel can accommodate different operating conditions. As shown in Fig. 7A and Fig., the operating voltage at the maximum power point will vary depending on whether the solar source is at or low temperature. Embodiments in accordance with the present invention provide extended performance by allowing MPP to accommodate any voltage limited impedance conversion. The converter is actually an O-DC-DC power converter in the full photoelectric temperature and voltage operating range, so that it can operate at the same low pressure as the MPP of the MPP during low temperature operation and the MPP at the time of high temperature operation. Thus, as can be seen from Figures 7A and 7B, the system can convert the photovoltaic power circuit to the photovoltaic power conversion control and the solar power source maximum power point thermal voltage deterministic photoelectric power conversion circuit. It can be realized that the rotation in the full photoelectric temperature and voltage operating range can be realized through the proper operation switching task cycle, and thus the system, the yang energy open circuit voltage, the deterministic task, the cyclic power distribution, and the solar energy 率w rate point thermal voltage decisive task cycle power distribution (switching) . In addition, observing the thermal and cold voltages, such as extreme conditions, similarly explains how the system accepts different amounts of solar radiation, so the system has an insolation-changing photoelectric conversion energy control circuit, regardless of whether the plate is blocked or even adjacent to the adjacent plate. Can extract MPP. The system and its ring distribution can be adapted to the amount of solar radiation, so the conversion step can be adapted to suit the change. This is especially noticeable in new technology boards such as cadmium telluride, especially when combining optoelectronics from boards with large operating voltages, ie, various 7B high temperature-independent boards. Control change. This is for the maximum work. It can be adapted to the sub-coverage task. The amount of radiant solar energy plate -23- 201037958 cadmium solar panel serial output. As early as possible, it is very important that the efficiency of the converter is running. This can be defined as the power that is output after converting the power from the previous conversion. A transistor switch that operates in switch mode achieves some efficiency gains, but topology is more important at this point. In particular, by operating the switches as described above, the system can far exceed the efficiency levels previously conceivable. It even achieves a fundamental power isomorphic opto-electronic DC-DC power conversion that does not convert power to heat but converts it to electrical energy, achieving efficiencies as high as approximately 99.2%. ^ This can be achieved by using the basic axiom isomorphic photoelectric converter function and the basic power isomorphic photoelectric impedance converter, as well as by controlling the operation switch, so the loss is limited as described above. This operation can achieve levels of 97, 97.5, 98, 98.5 or even up to 99.2 or essentially the efficiency of wire transmission losses (think of it may be higher). One aspect that helps achieve this efficiency is the minimum amount of energy stored during the conversion. As shown in Figures 5A and 5B, this embodiment can include a parallel capacitor and a series inductor. This can be used to store energy at least several times during the conversion run. It can be found that full energy conversion is not achievable, and the amount of conversion is necessary for the expected results obtained. Thus embodiments can function as low energy storage optoelectronic DC-DC power converters and even partial energy storage optoelectronic DC-DC power converters. In the case where the input voltage and the output voltage are almost equal to the unified conversion of the & converter, the energy storage hardly changes, so the system exhibits an embodiment of the photoelectric DC-DC power converter with substantially constant energy storage. The task cycle energy storage can be proportional to the voltage in the conversion (linear, continuous or not). The energy stored in the inductor -24- 201037958 can be proportional to the duty cycle of one or more switches. Partial efficiency is considered to be the result of the switch remaining static or open during operation. Thus the embodiment provides a photoelectric switching control circuit for static switch alternate mode, and similar, static switching. A step switch component control circuit is also provided. The switch can be controlled in the operational variable task cycle mode, thus changing the distribution frequency to achieve the desired effect. The converter functional control circuit (8) can function as a photoelectric task cycle switch control circuit. Task cycle operation ® and power distribution can achieve a variety of results, from the photoelectric impedance conversion task cycle to other operations. Some of these are even contrary to the conversion of the primary purpose of the optoelectronic DC-DC power converter (4). Although the above circuit surface is good in theory or in daily operation, there is an additional need for a system having practical functions. For example, the aforementioned dual mode circuit will produce an infinite output voltage if no load is present. This situation often occurs in practice. Consider the morning situation when the sun first illuminates the PV panel string with the power conditioner (17). There is no power network connection at this time, and the converter section does not pump any power. In this case, the power regulator (17) will increase its output voltage during actual operation until the converter is damaged. The converter has overvoltage protection on its input to add additional power conversion components, or the power regulator can simply have its own internal output voltage limit. For example, if each power regulator (17) produces a maximum voltage of 100 volts, the maximum output voltage of a series of 10 PCs in series will be 100 volts. This output voltage limit will make the net junction converter less complicated and expensive, and the voltage limit as shown in Figure 7A resetting the overvoltage limit. The embodiment can show the maximum voltage deterministic power distribution photoelectric power conversion control circuit and the maximum photovoltaic voltage deterministic task cycle power distribution (shown in Figure 7A with a reset overvoltage limit display) due to -25-201037958. It can be a specific converter. The maximum output current limit can also be very useful, as shown in Figure 7A as a preset overcurrent limit. This is less concise and involves the performance of the PV panel. If the PV panel is not exposed to sufficient light, its output voltage will decrease but its output current may not increase. The advantage is that only a small margin of variation is allowed for the extra current. For example, a board of the same 100 watts with a maximum voltage limit of 1 watt can have a current limit of 2 amps without limiting its intended use. This also greatly simplifies the subsequent state of the mesh converter. Consider the converter case in a large device that requires a front-end shunt breaker for protection. If the output of the PC reaches 100 amps, the circuit breaker will resolve the impractical current. This situation does not occur in non-PC environments, as a simple PV panel string can be easily damaged by the circuit breaker circuitry. Only a PC needs such a current limiting circuit and this can also be achieved simply by a task cycle or more precisely switching the operation control. Once the current limit is included in 〇 W another, BOS savings will be achieved. The interconnected wire sizes of serial PC strings are now limited to sizes that can only support the maximum current limit. The embodiments herein may represent a maximum photoinverter current converter functional control circuit, an inverter maximum current decisive power distribution, a photoreactor maximum current deterministic task cycle switch control circuit, and a photoreactor maximum current deterministic task cycle power distribution. Wait. Continue to discuss the issue of another system. In solar installations, extremes can also occur, where the board or board area receives more than full-day energy -26-201037958. This occurs when there is a fire condition and a cloud or other reflective surface. The PV source will produce approximately 1.5 times the rated power in a few minutes. The networked inverter section must be able to operate at higher power (increased cost) or must be avoided to some extent. The power limit of the PC is the most effective way to solve this problem. In general, the protection of some other components can be done by the converter. Even the back-end or downstream components such as inverters, so the converter functional control circuit (8) functions as a photo-inverter protection mode for photoelectric DC-DC power conversion and is considered to be a photo-electric inverter. The protection converter functionally controls the D circuit. In addition to protection, an ideal inverter or other operating condition can be implemented by a converter, and thus embodiments can include a converter functional control circuit for the operating conditions of the photoinvertor. This can be done in a simple manner by a series of adjustments, such as adjusting the modal or opto-inverter or back-end components through a photo-inverter or back-end component to adjust the converter's functional control circuitry. There are also embodiments with a smaller output voltage (within the allowable output voltage range). As shown in Figures 7A, 7B and 9, boundary conditions such as overcurrent limiting and overvoltage limiting can be set. Therefore, the converter and/or its control circuit functions as a functional control circuit of the optical D electric boundary condition converter, realizes the photoelectric boundary condition mode of the photoelectric DC-DC power conversion, and can complete the control of the photoelectric DC-DC converter. The steps of the photoelectric boundary conditions. Another mode of operation is to obtain a certain proportion (a broad sense) of ambiguity. For example, it is advantageous to generate a voltage proportional to the current to provide smooth starting performance and the like. It is thus configurable to control an embodiment of the maximum photo output voltage that is proportional to at least some number of photo-electric output currents during the step of converting the DC input to the DC output. In general, a soft-switching opto-electric power conversion control circuit is also available from -27-201037958. The system may include task cycle control or switching operation 'guided them to achieve one or more ratios between maximum voltage output and current output, and the like. Furthermore, it is not only possible to combine any of the above structures, and each of them can be categorized in a subsidiary manner. Therefore, one modal consideration is secondary to the other modality. They can be implemented by simply changing the duty cycle or switch affected by the switch. They can be completed according to the threshold and provide an optional mode for triggering the threshold, a threshold, a threshold, a threshold, a threshold, or a live power conversion control circuit. The operation of the pulse train mode can be realized, for example, when approaching a mode change level operation, and the averaging frequency can be alternated at this time, and the level can be lowered as the change back to the initial stage. This can also be transient. The photoelectric power conversion control circuit and the pulse train mode power distribution of the pulse train mode power distribution can be completed in this manner, and the photoelectric task cycle switch control circuit of the transient relative mode and the step of establishing the relative power distribution mode in the transient mode can be performed in this manner. carry out. As mentioned above, the PC and opto-electronic DC-DC power converter (4) can operate a single board. They can be attached to or separated from the board, frame. Embodiments have converters that are physically integrated with such boards, in the form of their attached units as final devices. This is highly desirable, such as when separate solar sources and adjacent solar sources have independent operating conditions to accommodate different solar radiation, conditions, or other conditions. Each board or the like implements its own MPP and is protected the same as other boards on the string.

It can be easily seen from the previous comments that an enhanced inverter that does not require control of MPP -28-201037958 and is selectively protected by the converter can be used. The inverter even has a separate control input so the input voltage can be optimized, such as a separate dessert shown in thick lines in Figure 9. Although other inventions of the assignee relate to these aspects, they are considered to be arbitrarily obtained from the converters described herein, and thus a more conventional inverter is shown in FIG. It provides connectivity to some types of AC power grid interfaces (9). As the invention becomes more recognized, it is still beneficial to compare it to more conventional techniques. This can be achieved by a simple switching operation in which the traditional mode is very cumbersome or easier to imitate. Thus, embodiments may include a solar power conversion comparator (29) to compare the first and second operational modes, or the improved mode of one embodiment of the present invention, as well as conventional less efficient modes. The comparator can include a display of some solar parameters for each panel. In this regard, it is beneficial to operate the inactive components in parallel switches. From here, we can see a variety of differences, such as solar output, solar efficiency differences, solar cost differences, solar solar utilization comparisons. ^ At least some of the following benefits can be achieved through the combination of these aspects and circuits: Each PV panel can achieve its single maximum power. Many current evaluations suggest that this can increase the power generated by 20% PV devices or higher. The networked inverter can be greatly simplified and more efficient operation. It can reduce the system running cost of the PV device. The circuits, concepts, and methods of various embodiments of the present invention are widely applicable. It can use one or more PCs on each board. For example, there may be inhomogeneities on the single -29-201037958 board or other reasons to derive power from the uniform portion of the board. It is also possible, for example, to optimize the power obtained from the board using a small power converter on the board portion. The invention expressly indicates the application including the sub-board. The invention is preferably used in a panel string. For example, it is economical to simply use a PC on each column of a large device. This is especially beneficial in parallel series. If a series of columns does not produce enough power to form a voltage, the remaining series will be generated. At this point, each string of PCs can increase the power gain of a large device. The invention is assumed to include a number of physical device options. For example, there may be a physical connection hardware between the PC and the board. An interconnect box can also be present in a serial array in which PCs are installed in each column. A given board can have one or more PCs that break into the board. All of the above are discussed in the field of solar power applications. It can be appreciated that even if not all aspects, portions can be applied to other fields. Thus, this description should be understood to support other applications of the converter, regardless of how it is applied and even whether it is used as a power converter, impedance converter, voltage converter or others. As can be readily seen from the above, the basic idea of the present invention can be embodied in a variety of ways. This includes both solar energy generation technologies and devices to achieve proper power generation. In the present application, power generation techniques are disclosed as part of the results achieved by various steps inherent in the circuits and devices and uses. They are a direct result of the use of the devices and circuits referred to. Moreover, while revealing the same circuits, it will be appreciated that they may not only perform a particular method but may also vary in a number of ways. More importantly, for the above, all of these aspects are to be understood as falling within the scope of this specification. The discussion included in this application is intended to be a basic explanation. Reading a particular discussion does not explicitly describe all possible real multiple options as uncertain. The nature is not fully described herein, and it is not explicitly shown how a feature or component may be in the art or have many alternative or equivalent components. Again, the statement is not explicitly stated. It is device-oriented that describes each function of the present invention implicitly. The device patents 〇 contain only the devices and circuits, and include methods or process variations to clarify the function of the invention and the function of each component. It is not intended to limit the scope of the application included in the subsequent patent application. It will be appreciated that variations may be made without departing from the elements of the invention. They are still within the scope of the invention. Variations of the illustrated embodiments, including the alternative embodiments, are included in the broad sense, and the description also includes a broadly defined method or process, and the invention is intended to be included in the scope of the patent application. Language changes and wider or more detailed patent protection will follow. On the basis of this understanding, the reader is informed that this specification supports all subsequent patent applications, and the applicant has the right to seek a wide range of content in the scope of the patent application, which is designed to cover the present invention. Multiple patents as well as a system as a whole. In addition, any of the various components of the present invention and the applicant for the patent box can be consciously applied; the invention is broadly described in the general disclosure of the invention, and the scope of the device is not limited to the patent specification or the patent scope to obtain a variety of clear and practical instructions. Or the understanding of the process should be understood as the aspect of the patent application with the basics; the circumference can be obtained in more than 31-201037958. In addition, when used or implied, an element should be understood to include a singular or a plurality of structures that may or may not be physically connected. This description is understood to include any such variations, any device embodiments, methods, or process embodiments, or merely variations of examples of variations of any of these components. In particular, it will be understood that the terms of each component may be expressed in equivalent device terms or method terms as long as the function or result is the same. Such equivalent, broader or generic terms are considered to include a description of each component or action. These terms may be substituted so that the scope of the invention is intended to cover the scope of the invention. Even if there is only one embodiment, it should be understood that all actions express a functioning method or a component that causes the action. Similarly, each physical component disclosed should be understood to include a disclosure of the actions that these physical components perform. With regard to this last aspect, even if there is only one embodiment, the disclosure of "converter" should be understood to include all "conversion" actions (whether or not explicitly discussed or not), and conversely, "conversion" actions This disclosure of effective disclosure should also be understood to include the disclosure of "converters," and "transformed devices." Such transformations and variations are to be understood as being expressly included in this specification.
