Abstract

本申请提供恒功率无线充电系统,涉及无线充电技术领域。本申请在不需要额外的转换层情况下,通过在初级侧的谐振补偿电路中引入补偿模块和无线电力传输模块,以及通过在半有源整流器的第二输入端接入一个脉冲密度调制控制波;这样,使得初级侧的谐振补偿电路向无线充电接收装置输出的输出电流与无线电力传输模块与次级侧的谐振补偿电路之间的互感无关,并且输出电流的值还可以通过调整补偿模块中各元器件的参数值来控制;以及在一个脉冲密度调制控制波周期内来调制初级侧的谐振补偿电路向无线充电接收装置输出的输出交流电压的占空比,进而来达到调节等效交流负载的目的,进而实现了无线恒功率充电,显着提高了系统效率并降低了系统复杂性和成本。
