Abstract :
The converting circuit requires high performance such as the output current with high accuracy, low ripple (les0.2 %) and full-range regulated in power accumulator battery testing system for electric vehicles (EV). In this paper, a three-phase current rectifier (CSR) is taken as the main circuit. Double-loop control strategy which is base on the feedback of grid current and the output current is used, the trigger signals of the IGBT uses the advanced space vector modulation (SVPWM) method. Finally, the power electronic simulation software PowerSim is used to simulate the various operating states of the modified topology circuit and its control strategy, the results of simulation show that the method in power accumulator battery testing system for EV is feasible.
