摘　　要：在电动汽车(Electric Vehicles,简称EV)用动力蓄电池组(Power Accumulator Battery,简称PAB)综合性能测试系统中,其变流输入部分性能要求较高,如输入电流的高精度、低纹波(≤0.2%)、全范围可调节等。变流输入部分主电路采用三相电流型整流器(CSR)拓扑结构,并使用了先进的空间矢量调制方式(SVPWM)和基于直流侧电流反馈、网侧电流反馈的双闭环控制策略。采用电力电子仿真软件Powersim对该拓扑电路进行计算机仿真。通过仿真实验验证了该控制方法在EV用PAB综合性能测试中应用的可行性。The converting circuit requires high performance such as the output current with high accuracy, low ripple （≤0.2%） and full-range regulated in power accumulator battery testing system for Electric Vehicles （EV）. In this paper, one three-phase current Rectifier （CSR） was taken as the main circuit. Double-loop control strategy which is base on the feedback of grid current and the output current was used, the trigger signals of the IGBT used the advanced space vector modulation （SVPWM）. Finally, the power electronic simulation software PowerSim was used to simulate the various operating states of the modified topology circuit and its control strategy. The results of simulation showed that the method in power accumulator battery testing system for EV is feasible
