Development of a modeling platform for 4.5 kV IGBT power modules

This paper deals with the development of a PSpice based evaluation platform for high power IGBT devices. The purpose of this platform is to provide useful information for the design and the assessment of converter cells for potential high power applications. An extended version of Hefner model is presented for high power, high voltage IGBTs taking into account temperature variation. A parametric analysis is presented in order to depict the effect of each parameter in the model. A set of parameters have been extracted and then verified with static and dynamic comparison of experimental data from 4.5 kV and 2.0 kA Si based IGBT power module (StakPak). Finally, an overall energy loss estimation is presented as function of temperature, load current and collector-emitter voltage.
