Abstract :
A new current driven synchronous rectification technology is presented. It is intended for high current and high efficiency applications. The synchronous rectifiers so presented are driven by current source instead of convention voltage source. This solves the problems of limited converter input voltage range and inability to operate in parallel in conventional voltage driven SR technology. The proposed synchronous rectification method is verified by practical converters with high efficiency recorded
