Abstract :
This paper is mainly concerned with a half-bridge voltage-clamped high frequency induction heating inverter circuit using a high-power bipolar-mode normally-off type static induction transistor, which efficiently operates in a zero current soft-switching (ZCS) mode. This proposed ZCS inverter is found to work safely with sufficiently high conversion efficiency. A new conceptional induction heating power supply is mentioned from a practical point of view
