摘　　要：针对谐振式无线供电系统初级线圈和次级线圈相对位置变化引起接收功率及输出电压变化的现象,以及二极管整流导致次级电路电流畸变和功率因数下降等问题,提出了一种基于PWM整流的电动汽车谐振式无线供电系统,即采用电压外环及电流内环的双环控制方法,以保证供电系统的单位功率因数及直流电压的恒定输出,并且利用ANSYS和MATLAB/Simulink仿真软件,分别研究电动汽车停车充电位置偏差对互感的影响及基于PWM整流的谐振式无线供电系统的性能,仿真结果验证了方案设计的有效性.In a resonant wireless supply system, the received power and output voltage change along with the relative position change between the primary coils and the secondary coils. Meanwhile, the current waveform in the received side is distorted and the power factor decreases due to the use of diode type rectifiers. An electric vehicle resonant wireless supply system based on PWM rectifiers was proposed to deal with these issues. By using double-loop control approach which was composed of outer loop voltage and inner loop current control, both system unity power factor and constant DC voltage output were achieved. The effects of parking position deviation on mutual inductance and the wireless supply system performance based on PWM rectifier were studied respectively by using the ANSYS and MATLAB/Simulink simulation softwares. The simulation results verify the correction of the system design.
