Implementation and validation of a physics-based circuit model for IGCT with full temperature dependencies

Abstract

This paper presents a physics-based Fourier solution IGCT model for circuit simulation with full temperature dependencies. Besides the external electrical characteristics, the model can also provide internal physical and electrical information of the device, such as the junction temperature, and the charge distribution. The model is shown to give good agreement with experimental waveforms and accurately predicts the device behavior under changing temperatures.
