Abstract

The authors present the concept and design of a parallel resonant converter for induction heating applications. The generators have a power range up to 200 kW. The inverter bridge, implemented with MOSFET transistors, can work to frequencies up to 200 kHz. The inverter is controlled by an automatic tracking circuit that makes certain that the resonant and inverter frequency are almost the same at every moment. The power delivered to the load is regulated by a feedback loop which controls the firing angle of the rectifier thyristors. After a description of the operative principle of the converter, the inverter control and design are outlined
