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.
