Research on Simulation and Electromagnetic Compatibility of External Traction to Electromagnetic Radiation of Train Traction Converter

构建变流器三维模型并简化,根据变流器实际电气参数,通过Matlab仿真得到模型的激励信号,之后利用电磁仿真软件分别对大功率逆变模块和牵引变流器进行电磁场仿真,得到各个部件对外的电磁场辐射云图及10m处探点电磁场强度的频谱曲线图并与实测数据进行对比,为后续对整车EMC的仿真研究提供了一定的参考和借鉴.

The three-dimensional converter model is constructed and simplified according to the actual electrical parameters of the converter,and the excitation signal of the model is obtained through simulation using Matlab.The high-power inverter module and the integral converter are simulated by the electromagnetic simulation software.The electromagnetic field radiation cloud diagram of the external module and the converter is obtained with the electromagnetic field at the 10 m probe point.The intensity spectrum diagram is compared with the measured data to provide a certain reference for the follow-up simulation of the vehicle EMC.
