Abstract

The purpose of this paper is to present a physics-based electro-thermal Saber model and parameter extraction sequence for high-voltage SiC buffer layer n-channel insulated gate bipolar transistors (IGBTs). This model was developed by modifying and extending the previously developed physics-based silicon buffer layer IGBT electro-thermal model and IGBT Model Parameter extrACtion Tools (IMPACT) to include SiC specific device and material properties. The validated simulation results in this paper demonstrate that the new electro-thermal Saber model for high-voltage SiC buffer layer n-channel IGBTs can be used to describe the static and dynamic behaviors for a wide range of device designs and circuit conditions for IGBTs with blocking voltages from 12 kV to 20 kV. The new physics-based model provides both device and circuit predictive capability.
