摘　　要：在电动汽车(ElectricVehicles,简称EV)用动力蓄电池组(PowerAccumulatorBattery,简称PAB)综合性能测试系统中,将传统的电流源型线性调节技术与整流和有源逆变技术有机地结合,提出利用电流源型线性调节器的工作特性来实现电流高精度、低纹波(≤0.2%)、全范围调节的方法;针对充电放电切换过程中可能出现的瞬时冲击电流问题,进一步推导出了限流电抗器的计算方法;采用电力电子仿真软件Powersim对改进的拓扑电路进行计算机仿真。通过仿真和电路实验验证了线性调节器在EV用PAB综合性能测试中应用的可行性。Associating the traditional linear regulate technique with the rectification and active inversion technique,a plan is presented,which can regulate the output current with high accuracy,low ripple（40.2%） and full-range by current source characteristic of the linear regulator in power accumulator battery testing system for Electric Vehicles （EV）.For the problem of transient surge current in charge and discharge switching process,further a method is deduced to calculate the limiting reactor.The power electronic simulation software Powersim is used to simulate the various operating states of the modified topology circuit, the results of simulation and experiment show that the application of linear regulator in power accumulator battery testing system for EV is feasible.
