| 摘 要： | 新一代复兴号动力集中动车组列车供电柜,首次采用二电平PWM整流器输出DC 600 V为客车供电。由于负载前端串联EMI滤波器,在负载投入时供电柜的滤波电感和EMI电容发生振荡,引起输出电压振荡。文章为抑制输出电压振荡,对输出端并联RC吸收电路和滤波电感并联RC两种方案分别进行讨论和验证,通过对主电路结构分析,认为滤波电感并联吸收电阻方案为最优。最后通过仿真和试验验证所提方案的可行性和有效性。

| Abstract: | Train power cabinet(TPC)of a new generation Fuxing power centralized EMUs used two-level PWM rectifier to supply DC 600 V for passenger cars.Because of series EMI filter at the front of load,when the load is put into operation,the filter inductance and EMI capacitance of the power supply cabinet will oscillate,resulting in the output voltage oscillation.In order to suppress the output voltage oscillation,two schemes of output parallel RC absorption circuit and filter inductor parallel RC were discussed and verified respectively.Through the analysis of the main circuit structure,the solution of filter inductor parallel absorption resistance was provided.Finally,the feasibility and effectiveness of the proposed scheme were verified by simulation and experiment. |
