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.
