Abstract :
This paper presents an accurate switching and conduction loss model for zero current switching (ZCS) and zero voltage switching (ZVS) IGBTs. Mathematical modelling is carried out giving careful consideration to all the significant features and dependant parameters, namely collector current, resonant frequency and case temperature. Model parameter extraction is carried out using the experimental results from two test circuits. The model shows excellent agreement with the experimental results and SPICE simulation results obtained using a physical IGBT model.
