Abstract :
This paper describes how the switching losses of IGBTs are influenced by the base resistance and its modulation due to the injected base charge. The calculation of the base resistance has been included in the IGBT model. It considers the shape of the charge carrier distribution in the dynamic case. With it, accurate results of the simulation are obtainable. This effect has been analyzed by measurements and simulations of two different IGBT-types. The influence of resistive and inductive load was also investigated. Parasitic elements in the commutation loop were taken into consideration
