Converters for induction heating applications are realized up to 1.5 MW using IGBTs [3]. Switching frequencies up to 150 kHz are realized with those IGBT inverters. For special purposes it is desirable to increase the frequency up to 500 kHz. These very high switching frequencies can be achieved using MOSFETs, but this is a very costly approach due to the large silicon area of MOSFETs and problems with the internal diode of the MOSFET [11]. In many applications a galvanic isolation between the… CONTINUE READING
