Basing on the technology of soft-switch, a novel two-switch LLC resonant inverter topology was proposed, which has solved the switching loss in traditional induction heating. To improve reliability of the power, current-feedback control mode and protection circuits were proposed. The method was simple and eased to realize. Experiment results effectively indicate the theoret- ic analysis that ZVS can be achieved in this circuit, and increase the work frequency of the power.
