Description

201134051 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 於與基於授權之無線電力的接收有關之方法及系統。 本申請案依據35 U.S.C. §l19(e)主張以下申請案的優先 權: 2009年11月17曰申請的題為「無線電力(wireless POWER)」之美國臨時專利中請案第6ι/262,ιΐ9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空中電力傳輸 (亦即’在充電器與正被充電之裝置之間不需要線連接的 犯里轉移)的做法。舉例而言,可借助於傳輸天線與待充
電之裝置上的接收夭綠# T 線之間的平面波輻射(亦稱為遠場輻 射)的耗合來轉移能量,該待充電之裝置收集所轎射之電 力且對其整流以用於斜雷 ……天線大體上為諸振長度 (耦口政率。此做法的缺點為電力耦合隨著天線之 間的距離增加而讯冻吝、p 思百亢琛之 4衷退。因此,ϋ常’超過合理距離 ,>1-2公尺)應用此充電解決方案變得困難。另外, 因為系統輕射单&、士 波,所以若未經由濾波來進行適當控 制,則無意之㈣可干擾其他系統。 I52225.doc 201134051 其他做法係基於嵌入於(例如)「充電」墊或表面中的傳 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 路之間的電感耦合。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)。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。 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」意謂 「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徹底理解的目的。 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 塊圆形式展示熟知結構及裝置以便避免混淆本文中所呈現 之例示性實施例的新穎性。 5「無線電力」在本文中用以意謂在不使用實體電磁導 ,之清況下自傳輸器傳輸至接收器的與電場、磁場 '電磁 场或其他者相關聯的任何形式之能量。應注意,本發明可 152225.doc 201134051 適用於任何合適之無線電力技術,諸如近場、遠場、譜振 及電感。 圓1說明根據本發明之各種例示性實施例的無線傳輸或 • 充電系統100。將輸入電力102提供至傳輸器1〇4以供產生 • 用於提供能量轉移之輻射場⑽。接收器1G㈣合至輻射場 106且產生輸出電力110以供耦合至輸出電力之裝置(圖 中未展示)儲存或消耗。傳輸器1〇4與接收器1〇8兩者分開 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HUM之賴頻率非常接近時,當接收器刚位於輻 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-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1〇8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 將傳輸天線之近射之大部分能量耗纟至接q欠天線而非以 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 . 間形成耦合模式。可發生此近場耦合的在天線114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 152225.doc 201134051 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的放大量來放大振盈器信 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104之阻抗與傳輸天線114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 展示)充電或對耦接至接收器之裝置(圖中未屐示)供電。可 包括匹配電路132以使接收器108之阻抗與接收天線118匹 配。接收器108與傳輸器1〇4可在一單獨通信頻道119(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 來實體裝置。此外,空心迴圈天線允許其他組件置放於心 區域内…卜’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)之耦合模式區可更強大。 如所陳述,在傳輸器104與接收器1〇8之間的匹配或近似 匹配諧振期間,發生傳輸器1〇4與接收器1〇8之間的有效率 月b量轉移。然而,甚至當傳輸器1〇4與接收器ι〇8之間的諧 振不匹配時’仍可讀低效率轉移能量。藉由將來自傳輸 天線之近場的能量麵合至駐留於建立&近場之鄰域中的接 收天線而非將㊣量自傳輸天線傳播至自由$間中來發生能 152225.doc 201134051 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 電容大體上添加至迴圈天線之電感以在所要諧振頻率下建 立一諧振結構。作為一非限制性實例,可將電容器i 5 2及 電容器154添加至該天線以建立一產生諧振信號156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 能量轉移區域增大。當然,其他諧振電路為可能的。作為 另一非限制性實例,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’諧振信號156可為至迴圈天線150之輸入。 圖4為根據本發明之例示性實施例之傳輸器2〇〇的簡化方 塊圖。傳輸器200包括傳輸電路202及傳輸天線2〇4。大體 而言,傳輸電路202藉由提供一致使在傳輸天線2〇4周圍產 生近場能量的振盪信號來將射頻(R F)電力提供至傳輸天線 204。舉例而言,傳輸器2〇〇可在13 56 頻帶下操 作。 例不性傳輸電路2〇2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,50歐姆)與傳輸天線2〇4匹 配,及低通濾波器(LPF)208,其經組態以將諸波發射減少 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J·生貫知例可包括不同濾波器拓撲(包括(但不限於)使 152225.doc 201134051 特定頻率衰減同時使其他頻率通過的陷波滤波器),且可 包括適應性阻抗匹配’該適應性阻抗匹配可基於可量測傳 輸量度(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202進一步包括經組態以驅動如 由振盪器212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組成。 來自傳輸天線204之例示性RF功率輸出可為約2 5瓦特。 傳輸電路202進一步包括控制器214,其用於在特定接收 器之傳輸階段(或作用時間循環)期間啟用振盪器2丨2、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可進一步包括負载感測電路216,其用於價 測在由傳輸天線2〇4產生之近場附近的作用中接收器之存 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210之電流,其受在由傳輸天線2〇4產生之近場附 近的作用中接收器之存在或不存在影響。對功率放大器 210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 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、塾、燈或其他不便攜帶之組態)相關聯。因此,傳 152225.doc 201134051 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 ' i >八才.、 电干上較小」(亦即,波 長之刀率)且經調譜以藉由使用電容器來界定言皆振頻率而 在較低可用頻率下諧振。在傳 , 寻掏天線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,。50公 :示性應用中’傳輸天線2〇4將未必需要較大數目之 匝來獲得合理電容。 傳輸器扇可搜集並追縱關於可能與傳輸器 接:器裝置之行縱及狀態的資訊。因此,傳輸器電路2〇2 =:接至控制器214(在本文中亦稱作處理器)之存在侦 測⑽、封入式债測器29〇,或其組合。控制器214可回 =來自存在偵測器扇及封入式制器29〇之存在信號而 调整由放大器210遞送之電力之量。傳輸器可經由若干電 、/、(諸如用以轉換存在於建築物中之習知A。電力的A。轉 DC轉換器(圖令未展示)、用以將習知dc電源轉換成適合 於傳輸器扇之錢的DC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#限制性實例,存在4貞測器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 的初始存在。在谓測之後’可開啟傳輸器且可使用由裝置 接收之RF電力來以預定方式撥轉以裝置上之—開關,此 情形繼而導致傳輸器之驅動點阻抗之改變。 作為另非限制性實例,存在偵測器28〇可為能夠(例 如)藉由紅外線债測、運動伯測或其他合適方式㈣人類

人類存在而將傳輸天線2〇4之功率#出調整至一管制位準 或較低位準,且當人類處於距傳輸天線204之電磁場一管 制距離之外時,將傳輸天線2〇4之功率輸出調整至一高於 該管制位準之位準。 作為一非限制性實例,封人式偵測器㈣在本文中亦可 稱作封入式隔間债測器或封入式空間伯測器)可為諸如感 测開關之裝置,其用於判定封入件何時處於封閉或開放狀 〜田傳輸器處於呈封入狀態之封入件中時,可增加傳輸 器之功率位準。 在例示性實施例中,可使用傳輸器扇藉以不會無限地 保持開啟之方法。在此狀況下,傳輸器2〇〇可經程式化以 在使用者决疋之時間量之後切斷。此特徵防止傳輸器 2〇〇(尤其是功率放大器21())在傳輸器2⑽周邊之無線裝置完 全充電之後長時間運轉。此事件可歸因於用以偵測自中繼 器或接收線圈發送之信號的電路之故障,該信號指示裝置 完全充電。為了防止傳輸器200在另_裝置置放於傳輸器 2〇〇周邊時自動地切斷’可僅在偵測到傳輸器2〇〇之周邊缺 152225.doc -10- 201134051 乏運動之設定時段之後啟動傳輸器200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才刀%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進一步耦接至裝置35〇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304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 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3〇4的阻抗匹配。接收電路 302包括電力轉換電路3〇6,其用於將所接收之源轉換 成供裝置350使用之充電電力。電力轉換電路3〇6包括111?轉 152225.doc 201134051 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310將經整流之RF能量信號轉 換成可與裝置350相容的勢能(energy potential)(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3〇6或替代地用於斷開電力轉 換電路306。將接收天線304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2〇〇包括負載感測電路216,其偵 測提供至傳輸器功率放大器2丨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。 當多個接收器300存在於傳輸器之近場中時,可能需 對-或多個接收器之加載及卸載進行時間多卫以使其他 收器能夠更有效率地耦合至傳輸器。亦可隱匿一接收器 便消除至其他附近接收器之紅人七,士 盗之耦合或減少附近傳輸器上之 載。接收器之此「卸載,在太令± + 丨戰J在本文中亦稱為「隱匿」。 外’如下文更完全地解釋,由垃故抵“

傳輸電路可藉由對功率放大器210使用開/關鍵控處理程 序來將k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21〇將在傳輸天線2〇4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216,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I上之電壓降形成於電力輸入信號226 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 之電壓降的改變。當傳輸天線與接收器(圖6中未展示)中之 接收天線處於耦合模式中時,由功率放大器21〇汲取之電 流之量將改變。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21〇消耗之電力之量將上升, 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23S之接收天線的存在且亦可偵 152225.doc 201134051 測自接收天線發送之信號。另外,接收器電流沒取之改變 可在傳輸器之功率放大器電流沒取中觀刺到,且此改變可 用以偵測來自接收天線之信號。 如本文中所使用,術語「實體」可指代在提供無線電力
