Modelling a Half-bridge de-de Converter Including the IGBT Module with Thermal Phenomena Taken into Account

Abstract

In the paper the problem of modelling characteristics of half-bridge dc-dc converters containing IGBT modules with thermal phenomena taken into account is considered. The form of the used electrothermal compact model of the IGBT module and the investigated converter are described. Some results of measurements and calculations of characteristics of the considered converter are shown and discussed. Particularly, temperature distribution in the IGBT module in different operating conditions of the considered converter are analysed.
