Electro-thermal model of a high-voltage IGBT module for realistic simulation of power converters

Abstract

This paper proposes the compact model development of a 6.5 kV field-stop IGBT module, for use in a circuit simulation environment. The model considers the realistic connection of IGBT-diode pairs: the description of semiconductor physics is coupled with self-heating effects; electro-magnetic phenomena associated with the package and layout are also taken into account. A selection of simulation examples demonstrates the validity of the proposed solution.
