Selection of SPICE Parameters and Equations for Effective Simulation of Circuits with 4H-SiC Power MOSFETs

Abstract

Power MOSFETs based on 4H-SiC have recently been commercialized and so circuit designers require SPICE models for simulation purposes in a range of applications including switch-mode power supplies. We present a selection of SPICE LEVEL 3 parameters and equations that can be used for effective circuit simulation of these MOSFETs, taking into account their unique characteristics for both static and dynamic operation.
