| Abstract |
This paper presents a novel type of voltage-fed quasi-load resonant half-bridge IGBT inverter operating at constant frequency variable power (CFVP) regulation scheme which is more suitable and acceptable for new high-frequency high-power induction-heated (IH) cooking appliances. This application-specific high-frequency inverter using a new generation specially-designed IGBTs can efficiently operate under a principle of ZVS-PWM
control strategy. The operating principle of a new inverter circuit is presented together with its power regulation characteristics on the basis of its computer-aided simulation analysis and its experimental results. The steady-state characteristics of cost effective quasi-resonant inverter developed for high-frequency IH cooking appliances such as multi-burner type IH cooker are
discussed herein from a practical point of view. |
