This paper presents a new prototype of voltage source-clamped quasi- resonant inverter, which is developed for the next-generation high-frequency high-power induction-headed (IH) Rice cooker. This application-specific high-frequency inverter using new-generation specially designed insulated gate bipolar transistors (IGBT's) can efficiently operate under a principle of zero-voltage switching pulsewidth modulation (ZVS-PWM) strategy. The ZVS operation condition on power regulation, loss analysis of new IGBT's incorporated into this inverter are discussed herein for IH Rice cooker.
