A systematic technique to modeling of power semiconductor devices for power electronic simulation

Abstract

Accurate power semiconductor device models are needed to predict large overshoot voltages and currents, switching power losses, conducted EMI etc. in the design of high performance, reliable power converters. A new systematic modeling technique, the lumped-charge modeling technique, is used to construct high power device models for power electronic circuit simulation. The lumped-charge models are composed of simple and continuous device equations and are valid over a wide range of operation. They represent a new generation of accurate power semiconductor device models.
