Temperature Distribution and Short Circuit Events in IGBT-Modules used in Traction Inverters

This paper proposes the study of IGBT-modules combining both inhomogeneous temperature distribution and short circuit events under realistic operational conditions. For this purpose, an IGBT-module compact model experimentally assisted by thermal mappings reproduces a railway traction application scenario. The results provide precious information for a reliable application of these components. Concretely, it is evidenced how package parasitics can strongly influence the electro-thermal behavior of the analysed IGBT-modules.
