Abstract

This paper presents methods of loss calculation of IGBT modules, operating in two-level half-bridge inverters with square-waveoutput. The equations for calculating IGBT module losses for typical collector current waveforms using linearly interpolated datasheetcurves are presented. Since this method is generally limited in accuracy, a better approximation of datasheet curves is introduced. In thesecond part the switching waveforms of experimental two-level half-bridge inverter based on two 6.5 kV Infineon IGBT modules areanalysed. Ill. 9, bibl. 13, tabl. 2 (in English; abstracts in English and Lithuanian).
