The invention provides an electric vehicle wireless charging system and a control method, and the electric vehicle wireless charging system comprises a power factor correction module, an inverter, a ground end control module, a transmitting coil, a receiving coil, a vehicle end control module and a rectifier. According to the wireless charging system for the electric vehicle, a DC/DC module is not arranged, the requirement of the system for voltage is met through PFC and INV, optimization of system efficiency is facilitated, and system cost and size are reduced. Meanwhile, when the wireless charging system of the electric automobile adjusts the current of the transmitting coil, it can be guaranteed that the inverter is in a soft switching state, and therefore high frequency of a power conversion device can be achieved easily.

    本发明提供一种电动汽车无线充电系统以及控制方法,其中,电动汽车无线充电系统包括:功率因数校正模块、逆变器、地端控制模块、发射线圈、接收线圈、车端控制模块以及整流器。本发明的电动汽车无线充电系统通过不设置DC/DC模块,由PFC和INV满足系统对电压的要求,有利于优化系统效率,降低系统成本和体积。同时,本发明的电动汽车无线充电系统在对发射线圈电流进行调节时,还能够保证逆变器处于软开关状态,进而有利于实现功率变换器件的高频化。
