| Abstract |
This paper presents a methodology for modeling the high-voltage silicon carbide (SiC) MOSFET/Junction-Barrier Schottky (JBS) diode power modules. The electrical model of an actual high-voltage SiC MOSFET/JBS module has been obtained using computer-aided electromagnetic analysis and verified through measurements. A circuit simulation model of a 2 kV, 5 A 4-H SiC MOSFET has also been built based on the Hefner MOSFET model and published experimental data. The device and package models are then combined and used to run circuit simulations of a double-pulse tester. The simulation results obtained provide good insight into the fast switching behavior and parametric dependencies of the paralleled SiC dice, which will aid in the module physical layout and gate driver design, as well as switching and conduction loss analysis. |
