中文摘要：

以某微型电动汽车电机驱动系统为研究对象，综合考虑其传导共模干扰和差模干扰相互之间的影响，构建了整个电机驱动系统传导EMI的预测分析模型。仿真预测结果与实测结果变化趋势一致，表明了所建立的电机驱动系统传导EMI预测模型的正确性和有效性。该电机驱动系统传导EMI预测模型可为电机驱动系统EMC方案设计提供理论分析手段。

英文摘要：

Considering the interaction of common mode interference and differential mode interference, we take the motor drive system of a mini electric vehicle as research object and build a predictive and analysis model of conducted EMI of the whole motor drive system. The results of simulative prediction and measured results show the same variation trend, which indicate that the built conducted EMI prediction model is correct and valid, and the model provides a theoretical analysis tool for the EMC design of motor drive system.
