Abstract

Intelligent power module (IPM) is known for its excellent features such as high compactness and ease-of-use. Some key points must be taken into account during the designing stage of an IPM. The internal Common-mode electromagnetic interference (CM EMI) is apt to cause an IPM to malfunction in normal operation. A practicable method of PCB layout is proposed in this paper to mitigate the CM EMI inside a newly-developed 6-in-1-packaged-IGBT-based IPM. Detailed analysis is given for the CM-EMI and its influence. Both simulation result and the experimental results verified the effectiveness of the method.
