Summary:Thermal stability of high-frequency insulated gate bipolar
transistor (IGBT) operation is studied in this paper. The
nonpunch-through IGBT is found to be stable when operated within its
rated temperature. Thermal runaway occurs with punch-through IGBTs at
temperatures below the maximum junction temperature when operated at
high frequency at well below rated current, with snubber or
soft-switching circuits
