Abstract

This paper presents a novel current driving method for the synchronous rectifier (SR) in a flyback topology. Compared to the previous proposed current driven synchronous rectifier (CDSR), the proposed CDSR features simple structure, low power loss and good performance. The proposed SR driving method is implemented in a 64 W flyback converter with universal input, and efficiency as high as 92.5% is achieved at low input (90 V AC) and full load condition.
