Abstract：A new hybrid full-bridge inverter which is suitable for ultra-high frequency induction heating power supplies was presented. The proposed topology has characteristics, which act as class-E inverter that the stray inductance of the input bus and the inverter output can be absorbed. Besides, the output capacitance of the switch can be absorbed by the resonance capacitance. This topology also makes it possible that no dead time is reserved for the complementary drives, and, if works properly, it can achieve Zero-Current-Switching(ZCS) and Zero-Voltage Switching(ZVS) turn-on and approximate ZVS turn-off. So it is suitable in the high frequency area. In this paper the characteristics and working principles were explained in detail and their validities was verified through several simulated and experimental results.
