Abstract :
The use of recently available high-voltage insulated gate bipolar transistor (IGBT) to improve switching performance of a gate turn-off (GTO) thyristor in a cascode configuration is documented. The IGBT-gated GTO-cascode switch features simple drive requirement, fast switching, robustness, and overcurrent protection. The cascode switch is applied in a quasi-resonant converter. Results indicate that IGBT-gated GTO-cascode switches are promising candidates for high-power and high-frequency applications
