Abstract

Current-fed parallel resonant converters with insulated gate bipolar transistors (IGBTs) working at frequencies up to 100 kHz for induction heating applications are presented. The power range of the described generators is 3 kW to 600 kW. The current derating of the IGBTs, according to the working frequency, is calculated. The influence in practical generators of the parasitic inductance between the output of the inverter and the resonant tank is shown
