An efficient semi-mathematical model for co-pack IGBT

An efficient and easily-realized semi-mathematical model of co-pack IGBT is proposed, based on existing built-in models for circuit simulator. With clamped inductive load there is strong interaction between the IGBT and the internal anti-parallel freewheeling diode (FWD) in the co-packed totem pole modules. This model provides a user-friendly co-pack IGBT model in which IGBT and its FWD are modeled as a whole. The comparison between simulation results and experimental waveforms has been made and good consistency is obtained in transient behavior.
