Description
This research details the high action pulse evaluation and corresponding modeling and simulation of a high voltage bipolar silicon carbide power device. A model of a high power bipolar device was developed in the Silvaco Atlas software to better understand the extreme electro-thermal stresses in the power device when subjected to an elevated-pulse current at a very unique time scale. Simulation of the on-state pulse current, device forward voltage drop, and lattice temperature profile of the pulsed power device will be presented in this research. The current density distribution through the bipolar device was analyzed and areas of localized very high current density were identified.
