Effects of the Internal Layout on the Performance of IGBT Power Modules

In this paper the issues of current sharing and gate interactions in IGBT power modules is addressed and the behavior is investigated by using a PEEC based simulation software, InCa, for modeling and parameter extraction. The behavior of power modules in a power converter is evaluated considering the high frequency parasitic effects. A comparison between two different power modules is carried out and the importance of the internal layout of both power and control section is point out.
