Gate oscillation during IGBT module short circuit is studied in this work. The distributions of carriers and electric field are simulated through Sentaurus TCAD. Mix-mode simulation is used for identifying influence of package parasitic on the gate oscillation. Elimination of the gate oscillation is achieved through module layout improvement.
