SPICE modeling and dynamic electrothermal simulation of SiC power MOSFETs

This paper presents a computationally efficient 3-D simulation approach for the dynamic electrothermal analysis of SiC power MOSFETs. The strategy relies on a circuit representation of the whole device, where the electrothermal feedback is enabled through an equivalent electrical network, and the elementary device cell is described by a novel behavioral model accounting for the non-intuitive temperature dependences of key physical parameters.
