Abstract: Basing on the technology of softswitch, a novel twoswitch LLC resonant inverter topology was proposed, which has solved the switching loss in traditional induction heating. To improve reliability of the power, currentfeedback control mode and protection circuits were proposed. The method was simple and eased to realize. Experiment results effectively indicate the theoretic analysis that ZVS can be achieved in this circuit, and increase the work frequency of the power.
Key words: ultrahigh frequency; induction heating; LLC resonant
