Abstract :
An improved self-driven synchronous rectification (SDSR) for a resonant reset forward converter is proposed in this paper. Three 9/spl sim/18 V input, 5 V/5 A output, 210 kHz resonant forward prototype converters with the conventional SDSR method, the gate charge retention SDSR method and the proposed method were constructed to compare their efficiencies. Experimental results prove that a relatively higher efficiency can be achieved with this proposed SDSR method.
