IGBT Modules: Data Sheet Comparisons and the Pitfalls of such Comparisons

January 31, 2012 // By Dr. Arendt Wintrich, Semikron
Comparing IGBT modules on the basis of data sheets is not as easy is it may seem. This is because IGBT manufacturers have always used different measurement methods for identical parameters. In real applications, this can lead to surprises such as far higher switching losses. This article takes a close look at the differentiation criteria of the most important functional properties and gives tips on how to better understand data sheets to enable more meaningful comparisons.
