Description

201134050 六、發明說明: 【發明所屬之技術領域】 本發明大體而言係關於無線電力,且更具體言之,係關 於用於基於條件之無線電力的方法及系統。 本申請案依據35 U.S.C· §119(e)主張以下申請案的優先 權: 2009年11月17日申請的題為「無線電力(WIRELESS POWER)」之美國臨時專利申請案第19號該案 之揭示内容藉此以全文引用的方式併入本文中。 【先前技術】 通常,藉由一可充電電池來供電之每一裝置可能需要其 自身的充電器及電源’該電源通常為一交流(AC)電源插 座。在許多裝置需要充電時,此舉變得難以使用。 正開發在傳輸器與待充電之裝置之間使用以電力傳輸 :亦曰即’纟充電器與正被充電之裝置之間不需要線連接的 里轉移)的做法。舉例而言,可借助於傳輸天線與待充 電之裝置上的接收天線之間的平面波輕射(亦稱為遠場輕 =)的麵合來轉移能量’該待充電之裝置收集所輕射之電 ==以用於對電池充電。天線大體上為諧振長度 間的距離心效率。此做法的缺點為電力耗合隨著天線之 二如迅速衰退。因此,通常,超過合理距離 1 公尺)應用此充電解決方案變得困難。另外, 因為系統輻射平面波, 制,貝,W ± 未經由滤波來進行適當控 制’則無意之輻射可傾其他系統。 152264.doc 201134050 其他做法係基於嵌入於(例如)「充電」墊或表面令的傳 輸天線與嵌入於待充電之主機裝置中的接收天線加整流電 路之間的電感耗合。此做法具有以下缺點:傳輸天線與接 收天線之間的間隔必須非常接近(例如,幾毫米卜雖然此 做法確實具有對同一區域中之多個裝置同時充電的能力, 但此區域通常較小,因此使用者必須將該等裝置定位至一 特定區域。 當使用者在家裏或在汽車裏對裝置充電時,使用者可選 擇來源並為所消耗之能量支付費用。在其他環境中,電力 之可用性及電力至經授權之使用者的遞送可能更有挑戰 性,此係因為來源之回應性與對充電之需要之間的關係可 能不再適用。 需要增強之系統及方法,該等增強之系統及方法用於將 無線電力轉移至經授權之使用者以及防止電力轉移至未經 授權之使用者。 【實施方式】 下文中結合隨附圖式所闡述之[實施方式]意欲作為對本 發明之例示性實施例的描述且不意欲表示可實踐本發明的 僅有實施例。遍及此描述所使用之術語「例示性」奄謂 「充當實例、例子或說明」,且未必應被解釋為相比其他 例示性實施例較佳或有利。該[實施方式]包括特定細節以 便達成提供對本發明之例示性實施例之澈底理解的目的。 熟習此項技術者將顯而易見的是,可在無此等特定細節之 情況下實踐本發明之例示性實施例。在一些例子中以方 152264.doc 201134050 圖:式展不熟知結構及裝4以便避免混清本文中所呈現 之例示性實施例的新穎性。 0=1…線電力」在本文中用以意謂在不使用實體電磁導 • 月況下自傳輸器傳輸至接收器的與電場、磁場、電磁 或其他者相„的任何形式之能量。應注意,本發明可 '用於任何。適之無線電力情況,諸如近場、遠場、諧振 及電感耦合。 圖1說明根據本發明之各種例示性實施例的無線傳輸或 充電系、、先1 00。將輸入電力102提供至傳輸器1 04以供產生 用於提供能量轉移之轄射場106。接收器⑽搞合至輻射場 1〇6且產生輸出電力11〇以供耦合至輸出電力11〇之裝置(圖 中未展不)儲存或消耗。傳輸器1〇4與接收器ι〇8兩者分開 達距離112。在-例示性實施例中,根據相互諸振關係來 組態傳輸器104及接收器108,且在接收器1〇8之諧振頻率 與傳輸器104之譜振頻率非常接近時,當接收器刚位於賴 射場106之「近場」中時,傳輸器1〇4與接收器1〇8之間的 傳輸損失最小。 傳輸器104進一步包括用於提供用於能量傳輸之構件的 傳輸天線114,且接收器108進一步包括用於提供用於能量 接收之構件的接收天線118。根據應用及待與之相關聯之 裝置來對傳輸天線及接收天線設定大小。如所陳述,藉由 將傳輸天線之近場中之大部分能量耦合至接收天線而非以 電磁波形式將多數能量傳播至遠場來發生有效率能量轉 移。當在此近場中時,可在傳輸天線114與接收天線118之 152264.doc 201134050 間形成耗合模式。可發生此近場耦合的在天線丨14及118周 圍的區域在本文中稱作耦合模式區。 圖2展不無線電力轉移系統之簡化例示性示意圖。傳輸 器104包括振盪器122、功率放大器124,及濾波器及匹配 電路126。該振盪器經組態以在所要頻率下產生信號,該 所要頻率可回應於調整信號123來加以調整。可由功率放 大器124以回應於控制信號125的放大量來放大振盪器信 號。可包括濾波器及匹配電路126以濾出諧波或其他不想 要之頻率且使傳輸器1 〇4之阻抗與傳輸天線i丨4匹配。 接收器108可包括匹配電路132及整流器及切換電路 134 ’以產生一直流(Dc)電力輸出以對電池136(如圖2中所 屐示)充電或對耦接至接收器之裝置(圖中未展示)供電。可 包括匹配電路132以使接收器1 之阻抗與接收天線丨丨8匹 配。接收器108與傳輸器丨〇4可在一單獨通信頻道丨丨9(例 如’藍芽、紫蜂(zigbee)、蜂巢式等)上通信。 如圖3中所說明,例示性實施例中所使用之天線可組態 為「迴圈」天線150,其在本文中亦可稱作「磁性」天 線》迴圈天線可經組態以包括一空心或實體心(諸如,鐵 氧體心)。空心迴圈天線可較能容忍置放於該心附近之外 來貫體裝置。此外,空心迴圈天線允許其他組件置放於心 區域内。另外,空心迴圈可更易於使得能夠將接收天線 118(圖2)置放於傳輸天線114(圖2)之平面内,在該平面 内’傳輸天線114(圖2)之麵合模式區可更強大。 如所陳述’在傳輸器104與接收器1 〇8之間的匹配或近似 152264.doc 201134050 匹配諧振期間,發生傳輸器104與接收器1〇8之間的有效率 能量轉移。然而,甚至當傳輸器104與接收器1〇8之間的諧 振不匹配時,仍可以較低效率轉移能量。藉由將來自傳輸 天線之近場的g量耦合至駐留於建立此近場之鄰域中的接 收天線而非將能量自傳輸天線傳播至自由空間中來發生能 量轉移。 迴圈天線或磁性天線之諧振頻率係基於電感及電容。迴 圈天線中之電感大體上僅為由該迴圈天線建立之電感,而 電谷大體上添力σ至迴圈天線之電感以在所要言皆振頻率下建 立二諧振結構。作為一非限制性實例,可將電容器Η〗及 電合器154添加至该天線以建立一產生諧振信號之諧振 電路因此,對於較大直徑之迴圈天線而言,誘發諧振所 需之電容的大小隨著迴圈天線之直徑或電感增加而減小。 此外,隨著迴圈天線或磁性天線之直徑增加,近場之有效 此里轉移區域增大。#然’其他賴電路為可能的。作為 非限制拴貫例,電容器可並聯地置放於迴圈天線之兩 個端子之間。另外,一般熟習此項技術者將認識到,對於 傳輸天線’譜振信號156可為至迴圈天線⑼之輸入。 圖4為根據本發明之例示性實施例之傳輸器的簡化方 塊圖°傳輸器200包括傳輸電路2〇2及傳輸天線2〇4。大體 而言:傳,202藉由提供一致使在傳輸天線—周圍產 近場此里的振盪信號來將射頻(RF)電力提供至傳輸天線 僅舉例而5,傳輸器2〇〇可在13.50 MHz ISM頻帶下 操作。 152264.doc 201134050 例示|±傳輸電路202包括固定阻抗匹配電路2〇6,其用於 使傳輸電路202之阻抗(例如,5〇歐姆)與傳輸天線2〇4匹 配,及低通濾波器(LPF)208,其經組態以將諧波發射減少 至防止耦接至接收器1〇8(圖丨)之裝置的自干擾的位準。其 他例示性實施例可包括不同滤波器拓撲(包括(但不限於)使 特定頻率衰減’使其他頻率通過的陷㈣波器),且可 u括適應]·生阻抗匹配,該適應性阻抗匹配可基於可量測傳 輸里度(諸如,至天線之輸出功率或由功率放大器汲取之 DC電流)而變化。傳輸電路2〇2進一 #包括經組態以驅動如 由振盪器2i2判定之RF信號的功率放大器21〇。傳輸電路可 由離散裝置或電路組成,或替代地可由整合式總成组成。 來自傳輸天線204之例示性尺!^功率輸出可為約2 5瓦特。 。。傳輸電路202進一 #包括控制器214,纟用於在特定接收 器之傳輸階段(或作用時間循環)期間啟用振盪器212、用於 調整該振盪器之頻率’及用於調整用於實施通信協定(用 於經由相鄰裝置所附接之接收器與相鄰裝置互動)的輸出 功率位準。 傳輸電路202可進一步包括負載感測電路216,其用於偵 測在由傳輸天線204產生之近場附近的作用_接收器之存 在或不存在。舉例而言,負載感測電路216監視流動至功 率放大器21G之電流’其受在由傳輸天線2()4產生之近場附 近的作用中接收器之存在或不存在影f。對功率放大器 21 〇上之負載之改變的偵測係由控制器214監視以用於判 定是否啟用振盪器212以傳輸能量以與作用中接收器通 152264.doc 201134050 信。 傳輸天線204可實施為天線條帶,其具有經選擇以使電 阻損失保持較低的厚度、寬度及金屬類型。在習知實施方 . 案中,傳輸天線204可大體上經組態以與較大結構(諸如, 桌子、墊、燈或其他不便攜帶之組態)相關聯。因此,傳 ^ 輸天線204大體上將不需要「阻」以便為實際尺寸。傳輸 天線204之例示性實施方案可為「電學上較小」(亦即,波 長之分率)且經調諧以藉由使用電容器來界定諧振頻率而 在較低可用頻率下諧振。在傳輸天線204之直徑或邊長(若 為正方形迴圈)相對於接收天線而言可較大(例如,〇 公 尺)的例示性應用中,傳輸天線2〇4將未必需要較大數目2 E來獲得合理電容。 傳輸器200可搜集並追縱關於可能與傳輸器2〇〇相關聯之 接收器裝置之行縱及狀態的資訊。因此,傳輸器電路加 可匕括連接至控制器2丨4(在本文中亦稱作處理器)之存在偵 測器280、封入心貞測器29(),或其組合。控制器川可回 應於來自存在_器28〇及封入式谓測器290之存在信號而 調整由放大器21〇遞送之電力之量。傳輸器可經由若° ^電 * 源(諸如,用以轉換存在於建築物中之習知AC電力的八〇轉 ' DC轉換器(圖中未展示)、用以將習知Dc電源轉換成適合 於傳輸器200之電屢的沉轉DC轉換器(圖中未展示》接收電 力,或可直接自習知DC電源(圖中未展示)接收電力。 作為一非限制性實例,存在偵測器28〇可為一運動偵測 器,其用以感測插入於傳輸器之涵蓋區域中的待充電裝置 152264.doc 201134050 的初始存在。在谓測之後,可胡轴难认。。 開啟傳輸态且可使用由裝置 接收之RF電力來以預定方式撥轉Rx裝置上之一開關,此 情形繼而導致傳輸器之驅動點阻抗之改變。 作為另一非限制性實例’存在福測器可為能夠(例 如)藉由紅外線谓測、運動偵測或其他合適方式摘測人類 的伯測器。在-些例示性實施例中,可能存在限制傳輪天 線可在-特定頻率下傳輸之功率之量的規則。在一些狀況 下,此等規則意欲保護人類免受電磁輻射。然而,可能存 在傳輸天線置放於人類未佔據的或人類很少佔據之區域 如車庫、廠區、店鋪,及其類似者)中的環境。若此 等^竟無^員’則可能可准許將傳輸天線之功率輸出增加 门於正吊功率限制規則。換言之,控制器214可回應於 人類存在而將傳輸天線2〇4之功率輸出調整至一管制:準 或較低位準,丑卷又牛s由i 且田人類處於距傳輸天線2〇4之電磁 其

乏運動之設定時段之後啟動傳輸器2〇〇自動切斷特徵。使 用者可能能夠判定停止使用(inactivity)時間間隔,且在需 要時改變該停止使用時間間隔。作為一非限制性實例,該 時間間隔可比在假定特定類型之無線裝置最初完全放電之 情況下對該裝置完全充電所需的時間間隔長。 圖5為根據本發明之例示性實施例之接收器3 〇 〇的簡化方 塊圖。接收器300包括接收電路3〇2及接收天線3〇4。接收 器300進步搞接至裝置350以向其提供所接收之電力。應 注意,將接收器3〇〇說明為在裝置35〇外部,但可將接收器 300整合至裝置350中。大體而言,能量係無線地傳播至接 收天線304且接著經由接收電路3〇2而耦合至裝置35〇。 接收天線304經調諧以在與傳輸天線2〇4(圖4)相同之頻 率下或幾乎相同之頻率下諧振。接收天線3〇4可與傳輸天 線204類似地來設定尺寸,或可基於相關聯裝置35〇之尺寸 來不同地設定大小。舉例而言,裝置35〇可為具有小於傳 輸天線204之直徑或長度的直徑或長度尺寸的攜帶型電子 裝置。在此實例中,接收天線3〇4可實施為多匝天線以便 減小調諧電容器(圖中未展示)之電容值且增加接收天線之 阻抗。舉例而言,接收天線304可置放於裝置350之實質周 152264.doc 201134050 長周圍’以便使天線直徑最大化且減小接收天線之迴圈匝 (亦即’繞組)之數目及繞組間電容。 接收電路302提供與接收天線304的阻抗匹配。接收電路 3〇2包括電力轉換電路3〇6,其用於將所接收之rFb源轉換 成供裝置35 0使用之充電電力》電力轉換電路306包括rf轉 DC轉換器308且亦可包括DC轉DC轉換器310。RF轉DC轉 換器308將接收天線304處所接收之rf能量信號整流成非交 流電力’而DC轉DC轉換器3 10將經整流之RF能量信號轉 換成可與裝置350相容的勢能(energy p0tentiai)(例如,電 壓)。預期各種RF轉DC轉換器,包括部分及全整流器、調 節器、橋接器、倍加器以及線性及切換轉換器。 接收電路302可進一步包括切換電路312,其用於將接收 天線304連接至電力轉換電路306或替代地用於斷開電力轉 換電路306。將接收天線3〇4與電力轉換電路3〇6斷開不僅 暫時中止對裝置350充電,而且改變如傳輸器2〇〇(圖2)所 「見到」之「負載」。 如上文所揭示,傳輸器200包括負載感測電路210,其偵 測提供至傳輸器功率放大器21〇之偏壓電流的波動。因 此,傳輸器200具有用於判定接收器何時存在於傳輸器之 近場中的機構。 田夕個接收器300存在於傳輸器之近場中時,可能需要 對或多個接收器之加載及卸載進行時間多工以使其他接 收益此夠更有效率地耦合至傳輸器。亦可隱匿一接收器以 便消除至其他附近接收器之麵合或減少附近傳輸器上之負 152264.doc 201134050 載。接收器之此「卸載」在本文中亦稱為「隱匿」。此 外,如下文更完全地解釋,由接收器300控制且由傳輸器 20(H貞測的卸載與加載之間的此切換提供自接收器3〇〇至傳 輸器200的通信機制。另外,一協定可與該切換相關聯, 該協定使得能夠將訊息自接收器300發送至傳輸器2〇〇。舉 例而言’切換速度可為約100微秒。 在一例示性實施例中,傳輸器與接收器之間的通信指代 裝置感測及充電控制機制而非習知雙向通信。換言之,傳 輸器使用所傳輸之信號之開/關鍵控,以調整能量在近場 中是否可用。接收器將此等能量改變解譯為來自傳輸器之 5孔息。自接收器側而言’接收器使用接收天線之調諸與解 除調諧來調整正自近場接受之電力的量。傳輪器可偵測來 自近場之所使用之電力的此差異,且將此等改變解譯為來 自接收器之訊息。 接收電路302可進一步包括用以識別所接收之能量波動 的發信號偵測器及信標電路3 14,該等能量波動可對應於 自傳輸器至接收器之資訊性發信號。此外,發信號及信標 電路3 14亦可用以偵測減少之rf信號能量(亦即,信標信 號)的傳輸且將該減少之RF信號能量整流成標稱電力以用 於喚醒接收電路302内的未供電或電力耗盡之電路,以便 組態接收電路302以用於進行無線充電。 接收電路302進一步包括處理器316,其用於協調本文中 所描述之接收器300之處理程序(包括對本文中所描述之切 換電路312的控制)。亦可在發生其他事件(包括偵測到向裝 152264.doc •13· 201134050 置350提供充電電力之外部有線充電源(例如,壁式/Usb電 源))後發生接收器300之隱匿。除控制接收器之隱匿之外, 處理器316亦可監視信標電路314以判定一信標狀態且擷取 自傳輸器發送之訊息。處理器316亦可調整DC轉Dc轉換器 3 1 0以獲得改良之效能。 圖ό展示用於執行傳輸器與接收器之間的訊息傳遞的傳 輸電路之一部分的簡化示意圖。在本發明之一些例示性實 施例中’可在傳輸器與接收器之間啟用用於通信之構件。 在圖6中,功率放大器21〇驅動傳輸天線2〇4以產生輻射 場。該功率放大器藉由載波信號22〇來驅動,該載波信號 220在傳輸天線204之所要頻率下振盪。使用傳輸調變信號 224來控制功率放大器21〇之輸出。 傳輸電路可藉由對功率放大器2 1〇使用開/關鍵控處理程 序來將信號發送至接收器。換言之,當確證傳輸調變信號 224時功率放大器21 0將在傳輸天線204上向外驅動載波 信號220之頻率。當否定傳輸調變信號224時,功率放大器 將不在傳輸天線2〇4上向外驅動任何頻率。 圖6之傳輸電路亦包括負載感測電路21 ό,其將電力供應 至功率放大器210且產生一接收信號235輸出。在負載感測 電路216中,電阻器^上之電壓降形成於電力輸入信號 與至功率放大器210之電力供應228之間。由功率放大器 210消耗之電力的任何改變將引起將由差動放大器23〇放大 之電磨降的改變。當傳輸天線與接收器(圖6中未展示)中之 接收天線處於麵合模式中時’由功率放大器210汲取之電 152264.doc 201134050 μ之量將改變》換言之,若傳輸天線2〇4不存在耦合模式 諧振,則驅動輻射場所需之電力將為第一量。若存在耦合 模式諧振,則由功率放大器210消粍之電力之量將上升, 此係因為大量電力耦合至接收天線中。因此,接收信號 235可指示耦合至傳輸天線235之接收天線的存在且亦可偵 測自接收天線發送之信號。另外,接收器電流汲取之改變 可在傳輸器之功率放大器電流汲取中觀測到,且此改變可 用以偵測來自接收天線之信號。 如一般熟習此項技術者將理解,商業機構(例如,咖啡 店)可向訪問該機構之消費者提供無線電力。更具體言 之’作為-實例,可由以下各者來提供無線電力存取:商 業機構、服務提供者、與商業機構或服務提供者達成協議
