无线电力充电系统
摘要：
一种无线电力充电系统，该系统包括无线电力传输装置（10），该装置（10）用于在传输控制单元（12）的控制下，通过谐振转换器（13）从初级铁芯（14）传输电力信号；和无线电力接收装置（20），该装置（20）用于通过次级铁芯（24）接收从无线电力传输装置（10）的初级铁芯（14）传输的电力信号并且在接收控制单元（22）的控制下给电池（21）充电。无线电力接收装置（20）包括在次级铁芯（24）侧的接收屏蔽板（25）和涡电流减少部件（26），用于屏蔽从次级铁芯（24）产生的电磁场，从而避免充电系统和电池受到电磁场的影响。
摘要（英）：

A non-contact power charging system includes a wireless power transmission apparatus 10 for transmitting a power signal from a primary core 14 via a resonant converter 13 by the control of a transmission control unit 12; and a wireless power receiving apparatus 20 for receiving the power signal transmitted from the primary core 14 of the wireless power transmission apparatus 10 via a secondary core 24 and charging a battery cell by the control of a receiving control unit. The wireless power receiving apparatus 20 includes a receiving shield panel and an eddy current reducing member in the side of the secondary core 24 to shield an electromagnetic field generated from the secondary core 24, to thereby protect the charging system and the battery pack from the electromagnetic field.
