摘　　要：城轨车辆牵引系统采用脉宽调制控制,具有高电压、大电流、脉冲干扰特性,作为主要的电磁干扰源之一,对列车系统的电磁兼容性产生重要影响;文章根据车辆系统设计,结合电磁干扰电流流通路径,分析牵引逆变系统主要电磁发射回路;通过建立高频干扰电流简化计算模型,研究减小牵引系统电磁发射的滤波参数设计方法,仿真对比各种滤波方案的抑制效果;最后,通过列车对外辐射发射测试验证优化方法的有效性。The traction system of urban rail transit vehicles is recognized as one of the main electromagnetic interference sources significantly impacting the electromagnetic compatibility of trains,primarily attributed to the implementation of pulse width modulation control,which involves high voltage,high current,and pulse interference characteristics.This study analyzed the main electromagnetic emission loops of the traction inverter system,taking into account both the vehicle system design and the flow path of electromagnetic interference current.By establishing a simplified calculation model for high-frequency interference currents,this study explored the method for designing filtering parameters aimed at reducing electromagnetic emissions from the traction system.Moreover,a comparative simulation was conducted to evaluate the suppression effects of various filtering schemes.Finally,the effectiveness of the proposed optimization method was verified by external radiation emission tests using trains.
