摘要
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 IGBT's at temperatures below the maximum junction temperature when operated at high frequency at well below rated current, with snubber or soft-switching circuits.
