Modelling dc characteristics of the IGBT module with thermal phenomena taken into account

In this paper the problem of modelling dc characteristics of the IGBT module is considered. The electrothermal model of such a module dedicated for the SPICE software is proposed. This model takes into account both self-heating phenomena in each component of this module and mutual thermal couplings between these components. Correctness of this model is veriried experimentally for one IGBT module of the type PSI25/06 by Power Sem.
