Application of Saber's simulation model IGBT1 in solid-state switch design

Saber,as a power electronic simulator,provides abundant universal models and special models for types of devices. The model IGBT 1 in saber for IGBT(Insulated Gate Bipolar Transistor) is introduced firstly,and its equivalent circuitry is presented. Its static and dynamic characteristics are studied,consisting of DC transfer characteristics,current distribution in parallel IGBTs and the turn-on process of IGBT. The IGBT 1 parameters relative to static and transient process are brought forward as well. When the proper parameters are selected,the simulative waves confirm the cal- culated results better. Its application in solid-state switch design is introduced.
