摘　　要：为了使直流充电桩的前级PFC有更高的功率因数,根据三相三电平Vienna PFC设计了一种作用于电压外环的模糊自整定PI控制器,根据三电平Vienna PFC dq坐标系下的数学模型、三电平空间电压矢量调制方法以及电流环的前馈解耦策略,在MATLAB/Simulink中建立了仿真模型,并进行仿真分析.仿真结果表明三相三电平Vienna PFC的功率因数接近1,有利于电网的电能质量改善.In order to improve the power factor of the front stage PFC of the DC charging station,a fuzzy self-tuning PI controller is designed based on the three-phase three-level Vienna PFC,which acts on the volt-age outer loop.Based on the mathematical model of the three-level Vienna PFC in the dq coordinate system,the three-level space voltage vector modulation method,and the feed forward decoupling strategy of the cur-rent loop,a simulation model is established in MATLAB/Simulink and analyzed through simulation.The simu-lation results show that the power factor of the three-phase three-level Vienna PFC is close to 1,which is bene-ficial to the improvement of the power quality of the power grid.
