摘要 针对基于E类逆变器的无线电能传输(WPT)系统中等效负载变化导致的硬开关问题,通过考虑源荷线圈耦合关系,分析多发射线圈等效耦合系数变化特征,得到发射端多线圈串联的线圈结构,实现了耦合系数及负载网络参数的动态调整,使等效负载在0~2Ropt(2倍理想负载)范围内均可实现软开关效果。最后通过仿真和实验验证该方法的可行性和有效性。

Abstract:In order to solve the problem of hard switching caused by the change of equivalent load in wireless power transmission system based on class E inverter. By considering the coupling relationship between the source and load coils, and analyzing the change characteristics of the equivalent coupling coefficient of multiple transmitting coils, the coil structure of multiple coils in series at the transmitting end is obtained, and the dynamic adjustment of the coupling coefficient and load network parameters is realized. The soft switching effect can be achieved within the range of equivalent load from 0 to 2Ropt (2 times the ideal load). Finally, the feasibility and effectiveness of the method are verified by simulation and experiment.
