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 2R_opt (2 times the ideal load). Finally, the feasibility and effectiveness of the method are verified by simulation and experiment.

Key words： Class E inverter wireless power transmission system source coil optimization soft switch
