And a voltage gain is (1 + D) 2 / (1-D), D is the duty cycle, the high voltage gain power conversion device.
升壓轉換器(Boost Converter)係廣泛應用於各種電器。而目前為了響應環保皆會利用綠色能源,如太陽能、風力能、地熱能、水力能、潮汐能、海洋能及生質能等,而綠色能源所產生的電力之電壓係為低電壓,因此,在使用上,需將綠色能源所產生的電力,經直流-直流轉換器進行升壓,方可進入換流器轉換成正弦電壓併入市電。Boost Converter is widely used in various electrical appliances. At present, in order to respond to environmental protection, green energy sources such as solar energy, wind energy, geothermal energy, hydropower, tidal energy, ocean energy and biomass energy are used, and the voltage generated by green energy is low voltage, therefore, In use, the power generated by the green energy needs to be boosted by the DC-DC converter before it can be converted into a sinusoidal voltage and integrated into the mains.
參閱第十四圖所示,係為一種傳統升壓型電源轉換裝置(A),包含有一輸入端(A1)、一電感器(A2)、一切換開關(A3)、一輸出二極體(A4)、一輸出電容(A5)及一負載(A6)。其中,該輸入端(A1)之一端係電性連接該電感器(A2)之一端。該輸入端(A1)之另一端係電性連接該切換開關(A3)之一端。該切換開關(A3)之另一端係電性連接該電感器(A2)之另一端與該輸出二極體(A4)之陽極端。而該輸出二極體(A4)之陰極端係電性連接該輸出電容(A5)之一端與該負載(A6)之一端。該輸出電容(A5)之另一端與該負載(A6)之另一端係電性連接該輸入端(A1)之另一端。其電壓增益比為:1/(1-D),D為責任週期,且D介於0至1之間。Referring to FIG. 14, a conventional step-up power conversion device (A) includes an input terminal (A1), an inductor (A2), a switch (A3), and an output diode ( A4), an output capacitor (A5) and a load (A6). Wherein one end of the input terminal (A1) is electrically connected to one end of the inductor (A2). The other end of the input terminal (A1) is electrically connected to one end of the switch (A3). The other end of the switch (A3) is electrically connected to the other end of the inductor (A2) and the anode end of the output diode (A4).

The voltage gain ratio is: 1/(1-D), D is the duty cycle, and D is between 0 and 1.
然而,為盡量提高電壓增益,該傳統升壓型電源轉換裝置需操作於較高的責任週期,但在較高的責任週期操作下,受到功率元件及電感器的串聯等效電阻等寄生(parasitic)元件的影響,造成能量損失增加,反而限制了電壓增益。因此,進一步有一改善傳統升壓型電源轉換裝置(A)之切換電感式升壓型電源轉換裝置(B),如第十五圖所示,該切換電感式升壓型電源轉換裝置(B)包含有一輸入端(B1)、一第一二極體(B2)、一第二二極體(B3)、一第三二極體(B4)、一切換開關(B5)、一第一電感器(B6)、一第二電感器(B7)、一輸出二極體(B8)、一輸出電容(B9)及一負載(B0)。其中,該輸入端(B1)之一端係電性連接該第一電感器(B6)之一端與該第三二極體(B4)之陽極端。該第一電感器(B6)之另一端係電性連接該第二二極體(B3)之陽極端與該第一二極體(B2)之陽極端。該第二二極體(B3)之陰極端係電性連接該第三二極體(B4)之陰極端與該第二電感器(B7)之一端。該第二電感器(B7)之另一端係電性連接該第一二極體(B2)之陰極端、該切換開關(B5)之一端及該輸出二極體(B8)之陽極端。該輸出二極體(B8)之陰極端係電性連接該輸出電容(B9)之一端與該負載(B0)之一端。該輸出電容(B9)之另一端、該負載(B0)之另一端與該切換開關(B5)之另一端係電性連接該輸入端(B1)之另一端。其電壓增益比為:(1+D)/(1-D),D為責任週期,且D介於0至1之間,然而,其電壓增益比仍有再提高的空間。However, in order to maximize the voltage gain, the conventional step-up power conversion device needs to operate at a higher duty cycle, but under high duty cycle operation, it is parasitic by the series equivalent resistance of the power component and the inductor (parasitic The effect of the component causes an increase in energy loss, which in turn limits the voltage gain. Therefore, there is further provided a switching inductive step-up type power conversion device (B) for improving the conventional step-up power conversion device (A). As shown in FIG. 15, the switching inductive step-up type power conversion device (B) The invention comprises an input terminal (B1), a first diode (B2), a second diode (B3), a third diode (B4), a switch (B5), and a first inductor. (B6), a second inductor (B7), an output diode (B8), an output capacitor (B9), and a load (B0). One end of the input terminal (B1) is electrically connected to one end of the first inductor (B6) and the anode end of the third diode (B4). The other end of the first inductor (B6) is electrically connected to the anode end of the second diode (B3) and the anode end of the first diode (B2). The cathode end of the second diode (B3) is electrically connected to the cathode end of the third diode (B4) and one end of the second inductor (B7). The other end of the second inductor (B7) is electrically connected to the cathode end of the first diode (B2), one end of the switch (B5), and the anode end of the output diode (B8). The cathode end of the output diode (B8) is electrically connected to one end of the output capacitor (B9) and one end of the load (B0). The other end of the output capacitor (B9), the other end of the load (B0) and the other end of the switch (B5) are electrically connected to the other end of the input terminal (B1). Its voltage-gain ratio is: (1+D)/(1-D), D is the duty cycle, and D is between 0 and 1, however, its voltage gain ratio still has room for improvement.
再者,有一高升壓比電源轉換裝置之專利前案,如中華民國發明專利公告第I429176 號「高升壓比直流轉換器」,係其第一、二開關受一控制晶片之控制,而依序呈現第一、二開關皆導通、第一開關導通、第二開關截止、第一、二開關皆導通、第一開關截止、第二開關導通,使一第一、二電感器與一第一、二箝位電容器對一第一、二輸出電容器釋能,令該第一、二輸出電容器儲能後對一負載釋能。如此,直流電源輸出至負載之電源電壓,因第一、二輸出電容器之釋能而升壓,升壓比為4/(1-D)。然而,該前案係使用二個切換開關,需考慮其切換損失(Switching Loss)對於轉換效率的影響。Furthermore, there is a patented high-boost ratio power conversion device, such as the Republic of China Invention Patent Publication No. I429176 "High Boost Ratio DC Converter", in which the first and second switches are controlled by a control chip, and The first and second switches are both turned on, the first switch is turned on, the second switch is turned off, the first switch and the second switch are turned on, the first switch is turned off, and the second switch is turned on, so that a first and second inductors and a first The first and second clamp capacitors release energy to a first and second output capacitors, so that the first and second output capacitors are capable of releasing energy to a load after being stored. Thus, the power supply voltage output from the DC power supply to the load is boosted by the release of the first and second output capacitors, and the boost ratio is 4/(1-D). However, the former case uses two switches, and the impact of switching losses (Switching Loss) on conversion efficiency is considered.
綜合上述,習知係具有下列缺失:In summary, the conventional system has the following deficiencies:
1.習知如第十四圖之傳統升壓型電源轉換器,其電壓增益比為1/(1-D),需操作於較高的責任週期,受電路之寄生元件的能量損失,會限制其電壓增益。1. The conventional step-up power converter of the fourteenth figure has a voltage-gain ratio of 1/(1-D), which needs to operate at a higher duty cycle, and is subject to energy loss of parasitic components of the circuit. Limit its voltage gain.
2.習知如第十五圖之切換電感式升壓型電源轉換器,其電壓增益比為(1+D)/(1-D)。但,其電壓增益比仍有再提高的空間。2. The switching inductive step-up power converter of the fifteenth figure has a voltage gain ratio of (1+D)/(1-D). However, there is still room for improvement in its voltage gain ratio.
3.專利前案「高升壓比直流轉換器」之電壓增益比為4/(1-D),但該專利前案使用兩個切換開關,需考慮切換損失對於轉換效率的影響。3. The voltage gain ratio of the patented "high step-up DC converter" is 4/(1-D), but the patent uses two switches, considering the effect of switching loss on conversion efficiency.
