Abstract

This invention provided a circuit system of a synchronous rectifier at least comprising a set of transformer composed of one primary winding coil and one secondary winding coil that can transform an input voltage into an output voltage. The circuit system also comprises a secondary forward synchronous rectifier switch, a secondary freewheeling synchronous rectifier switch, a secondary driving winding coil, and one Zener diode.
