摘　　要：研究了大电流混合封装电力电子集成模块 (IPEM)内功率电路对控制驱动电路的电磁干扰问题研究表明 ,功率电路的内部环流通过互感耦合的方式会对IPEM内部的控制和驱动电路产生重要影响 ,特别是环流的高频分量为了对环流的EMI进行评估 ,建立了IPEM的内部环流实验模型另外 ,一种简化的基于局部元等效电路 (PEEC)原理的建模和计算方法被用于计算环流回路与控制和驱动回路之间的互感 ,实验证明结果是比较准确的 .This paper deals with the electromagnetic interference problem based on mutual inductance model between the power circuit and control and driver circuit in hybrid Integrated Power Electronic Module (IPEM). It shows that the high frequency components of the circulating current of power circuit have important influence on control and driver circuit. An IPEM prototype is built up to evaluate the EMI of the circulating current. And an effective modeling and calculation method based on Partial Element Equivalent Circuit (PEEC) is used to calculate mutual inductance between the power circuit and control and driver circuit.
