Abstract :
This paper presents a SPICE macromodel for a 1-megawatt high power electrical switch which uses power MOSFETs as the active switching elements. The model accurately predicts the time dependent switching current and provides a reasonable representation of the time dependent switch resistance and voltage drop across the switch. Techniques for extracting model parameters for commercial power MOSFETs are discussed along with suggestions for extending the model to spark gaps and other high power switches
