摘要：
A novel clamp circuit applied to the flyback converter is proposed to improve the efficiency of the active clamp flyback converter during light load. The proposed clamp circuit combines the active clamp circuit and the transient voltage suppression (TVS) circuit which belongs to the passive clamp circuit. Therefore, during light load, the MOSFET switch of the active clamp circuit is always turned off and TVS circuit is used to suppress the voltage spike whereas during heavy load, only the active clamp circuit is used to suppress the voltage spike. The experimental results show an approximately 5% increase in efficiency during light load as compared to the traditional active clamp flyback converter.
