Abstract: In the research of the radio energy transmission system of electric vehicles, aiming at the problem of the harmonic after the high-frequency inverter, a compensation method is proposed based on LCL-S. This article analyzes the constant-current characteristics of LCL compensation network and a resistive input impedance after compensation. The power factor of the system is improved and transmission characteristic of the system are more stable and efficient. Maxwell, MATLAB and Simplorer are used to carry out joint dynamic simulation and verification of the topology selection of compensation link. The simulation results show that the simulation waveform after LCL-S compensation is more stable. The results show that the transmission characteristics of electric vehicle wireless charging system under LCL-S compensation topology are good.
