Abstract

For an electric vehicle (EV) wireless charging system, the stable output and efficient operation of the system are essential. This article first analyzes the characteristics of the wireless charging system based on the dual-LCC compensation topology network, and initially designs the parameters based on the efficiency model. Then the input impedance model of the rectifier bridge is established, which contains two parts: resistance and inductance. On this basis, a compensation network parameter optimization method based on rectifier input impedance analysis is proposed. Finally, a MATLAB simulation model is built, and the effectiveness and feasibility of the proposed optimization method are verified through the simulation results. With the parameter optimization method proposed in this paper, the system can achieve good constant output performance and high efficiency.
