| Abstract |
This paper describes an advanced prototype of voltage-fed zero voltage soft-switching PWM resonant inverter with an active voltage clamped capacitor, which is put into practice for high-frequency high-power induction-heated appliances used in the field of consumer power electronics. This application-specific quasi-resonant inverter using the latest generation IGBTs for soft-switching can regulate its output power under a principle of a fixed frequency ZVS-PWM strategy. Its operating principle and unique features are presented as compared with a conventional quasi-resonant ZVS-PFM inverter, together with its power regulation characteristics on the basis of its computer-aided simulation and experimental results. The steady-state performances of this inverter developed for two-burner type induction-heated food cooking appliance, induction heated steamer induction-heated boiler, and induction-heated fryer are discussed, induction heated steamer and evaluated from a practical point of view. |
