Abstract A novel multiple-frequency power supply is proposed for high frequency high power induction heating appliances based on center-tapped transformer. Its output frequency is as twice as the device frequency, by using two symmetrical half bridges, sharing two equal resonant capacitances and coupling with center-tapped transformer. Each power switch has zero voltage switch (ZVS) soft switching characteristic, and its conduction time is only a quarter of switching cycle. Thus the power consumption of the switches decrease significantly compared with the traditional inverter. The eight operation modes are analyzed, and the design methods of circuit parameters are also present. Taken IGBT as power switches, a prototype is designed to verify the power supply topology, the theoretical analysis and the circuit parameter selection method.
