摘要

提出了一种基于相移控制策略的电动汽车动态无线充电(EV-DWC)系统快速软启动方法。首先，建立了基于双面LCC补偿网络的EV-DWC系统交流阻抗模型;提出了一种抑制逆变器输出电流超调的方法。然后采用全桥逆变器相移与模糊PID相结合的控制方法，实现系统的快速动态响应。最后，搭建了输出功率为15kw的EV-DWC系统实验样机，实现了逆变器输出电流5ms的稳定时间。仿真和实验结果验证了该方法的可行性和有效性。

Research on Fast Soft-Starting Methods for Electric Vehicle Dynamic Wireless Charging System

This paper proposes a fast soft-starting method based on phase-shift control strategy for electric vehicle dynamic wireless charging (EV-DWC) system. Firstly, the AC impedance model of the EV-DWC system is established based on the double-sided LCC compensation network. The overshoot suppression method for the output current of the inverter is presented. Then the control method combining phase-shift and fuzzy PID of full-bridge inverter is adopted to achieve fast dynamic response of the system. Finally, an experimental prototype of the EV-DWC system with the output power of 15kw is built, which archives 5ms settling time of the output current of the inverter. The simulation and experimental results proves the feasibility and effectiveness of the proposed method.
