A simplified spice based IGBT model for power electronics modules evaluation

The paper deals with the evaluation of a suitable model for power IGBTs targeted for use in power electronic modules. The main issue for the developed model is the possibility of creating a circuital based structure starting from the device physical equations. The model is implemented in a circuital simulation environment with the aim of evaluating the performance of high voltage, high current modules. In those a key factor is the possibility of having computation times fitting with the necessity of parasitic elements estimation. The implementation of the model is described together with the validation of it by comparison with experimental results.
