201014108 六、發明說明： 【發明所屬之技術領域】 此案請求優先權，且對美國暫時申請編號60/444,794有幫助， 標題為可調性感應耦合穩定電路(c〇upled Banast Circuit) ’此由
David W. Baarman申請於2003年2月4曰。全部揭發在申請前合併 於此作為參考。此案為美國專利申請序列編號1〇/175,〇95(標題為用 於流體處理系統的射頻辨識系統，申請於2002年6月18日）的延續 部分’此為美國專利申請序列編號〇9/592，194(標題為具電感耦合安 ❹ 定器的流體處理系統’申請於2000年6月12日）的延續部分。美國 專利申請編號09/592,194於美國臨時專利申請序列編號 60/140,159(標題為具有感應麵合穩定的水處理系統，申請於1999年 6月21日）及美國臨時專利中請序列編號60/14〇,〇9〇(標題為針對使 用的水處理系統，申請於1999年6月21曰）的35 U.S.C.§119(e)下 申請裨益。 此案由參考合併下面在相同日期申請，並分配至如此案的相同 受託人：適應性感應能量供給聯繫，序列編號為10/689148;感應繞 組裝配’系列編號為10/689224;靜電儲存裝配，序列編號為 ® 10/689154，以及轉接器，序列編號為10/689375。 【先前技術】 此發明一般為關於非接觸式電源供應器，且更明確為感應耦合 非接觸式電源供應器。 非接觸式能量傳送系統(CEETS)將電能自一設備轉移至另一 設備，此無須任何機械連接。因為無機械連接，CEETS可具有超過 傳統能量系統的優點。一般較安全，因為有少數火花或觸電的危險 (由於電源供應器分離）。也有益於具有較長壽命，因為沒有接觸而 3 Weeunto Ϊ\«/·0*Μ〇07· 丨 201014108 磨損。由於這些優點’ CEETS已使用於每樣事物，從牙刷至可攜 電話至列車。 $ CEETS由電源供應器及遠距裝置組成。遠距裝置可為可充電 的，比如電池、微電容器或任何其他可充電的能源。或者，ceets 可直接驅動設備。 一種CEETS使用磁性感應來轉移能量。能量從電源供應器中 的一次繞組感應轉移至可充電設備中的二次繞組。因為二次繞組物 理上與一次繞組保持間隔，感應輕合經由空氣發生。 在一次繞組及二次繞組之間沒有物質連接，傳統反饋控制並不 存在。因此’在CEETS巾自-次至二摘能量轉雜制躺難的。 共同溶液設計成CEETS致力於一種設備。舉例來說，可再充 電牙刷的CEETS僅設計成使牙刷再充電，同時可再充電電話的 CEETS僅使用特定種類的電話工作。儘管此溶液允許CEETS與一 特殊設備有效運轉，此未能充分彈性允許電源供應器與不同可再充 電設備操作。 顯然，製造每個特定可充電設備的CEETS乃費用高且效率 低。因此，非接觸式能量傳送的系統為有效的，並可大大理想使用 多數各種設備。 〜 〇 【發明内容】 上述問題在本發明中可克服。 非接觸式電源供應器經由儲能電路(tajjk circuit)感應至一設 備。電源供應器具有動力式調整儲能電路之共振頻率(res〇nant frequency)的控制器。儲能電路可具有電容器或可變電感器或二者。 在一實施例中，電源供應器也可具有一反向器。連接至反 向器的驅動電路控制反向器的頻率及反向器的工作循環。附加記憶 4 1^Λΐ·065·0007·1·^5ρ*·09111ί.Ρ〇( 201014108 voltage) ° 經由驅動電路指導反向器操作。或者，反向器也可連 -(直流電)電源。然後控制器可變化DC電源的軌道電壓㈣ 由改魏能電路的共振鮮、反向11的辭、反向器的工作 2祕應騎軌道㈣，非制式電·應器可供給各種不 ^叹備。電源供絲敍可同雜給數個不肖設絲量。此提 ς不同設鶴力的能力克服料與CEETS有_事先限制。進一
