Abstract :
In this paper, implementation and limitation of thermosensitive parameters when predicting junction temperature in a hybrid module is discussed and some remedies are presented for this purpose. The results obtained by applying two important thermosensitive parameters of an IGBT show that equivalent temperature predicted by these parameters is not a simple average of individual chip temperature but is rather near to the hottest one. The results of different tests are presented and a generalized method (temperature sensitive parameter method) for using these parameters is explained
