This paper deals with the active clamp ZVS flyback converter for RF generator. The proposed converter has the characteristics of the low switching noise and high efficient regarding conventional flyback converter. To verify validity of the proposed converter, the 100kHz, 48V, 300W converter are simulation and experimental result. This converter will be apply to the discharge drive circuit for PDP(Plasma Display Panel) TV.

This paper analyzed PFC of active clamp ZVS flyback converter by adding two method PFC (Power Factor Correction) circuit - Two-Stage and Single-Stage.<br/> It improves on Flyback converter's disadvantage - loss increasing by switching, noise increasing, high voltage stress of switch - by adding active clamp circuit. Simulation results show to improve the input PF of 300W ZVS flyback converter by adding Single-Stage, Two-Stage PFC circuit.
