A compact model for SiC Power MOSFETs is presented. The model features a physical description of the channel current and internal capacitances and has been validated for dc, CV,and switching characteristics with measured data from a 1200-V, 20-A SiC power MOSFET.

The SiC Power MOSFET model presented here is based on the analytical model published in [1] and [2]. A 1200 V, CREE device (C2M0025120D) has been used in this work to illustrate the parameter extraction and model validation. Chapter 2 explains the process of parameter extraction sequence using the device datasheet and Chapter 3 shows the model validation using double pulse tester circuit. Chapter 4 shows the comparison between MAST and Verilog-A codes of the model. Chapter 5 entails all the parameters used in the model and Chapter 6 comprises of the model equations. Finally, chapter 7 includes the people involved in this project.
