Abstract :
This paper describes quasi-resonant converter for induction heating in high temperature application. Converter is implemented by using IGBT as its switching. The switching loss is minimized by operating the IGBT in the zero voltage resonance modes. The output power can be adjust by varying the switching frequency of converter. The prototype is tested under load-parameter variation during the heating process and it is rated at approximately 1000W, with operating frequency ranging from 5-7 kHz. The operation principles of quasi-resonant are investigated and validity is verified by simulation and experimental results.
