| 摘 要： | 基于电机传导电磁干扰产生机理的分析,建立可对电机传导电磁干扰进行仿真的电路模型,同时考虑了高频段电机绕组分布参数的影响.电流换向过程是电机产生传导干扰的主要原因.通过分析换向过程的等效电路,计算出换向过程中的传导射频发射电压,并提取电机绕组的分布参数,利用等效集总网络来描述分布参数的影响,建立电机传导干扰的仿真模型.利用OrCAD/PSpice软件对实际电机的传导电磁干扰进行了仿真,通过实测和仿真结果的对比验证了模型的正确性.

| Abstract: | A simulation model for evaluation of conducted electromagnetic interference(EMI) is developed based on analysis of the mechanism giving rise to conducted EMI.The simulation model includes high frequency effects associated with stray distributed parameters.The current commutation in armature coils is identified as the main cause of conducted EMI.Based on analysis of current commutation,the voltage of conducted EMI is calculated and an equivalent lumped parameter network is presented to replace the effects of... |
