Abstract :
This paper is mainly concerned with a half-bridge quasi-resonant voltage-clamped high-frequency induction-heating inverter circuit using a high-power bipolar-mode normally-off type static induction transistor (B-SIT) for soft-switching, which efficiently operates at a zero-current soft-switching (ZCS) mode. This proposed inverter using newly developed B-SIT module is more suitable for modern induction-heating power supplies. Its new conceptional operating principle is basically presented and its features are discussed. Its computer-aided simulation results are illustrated as compared with the experimental results obtain from a trially-produced breadboard with parallel load resonant tank
