Abstract :
The self-driven synchronous rectification schemes for asymmetrical topologies have been studied in this paper. Some rules about the conduction of SRs body diode are found. Based on these rules, several ideal self-driven SR circuits without body diode conduction have been proposed. A laboratory prototype with one of the proposed ideal self-driven SR circuits is built up to verify the theoretical analysis and relatively high efficiency has been achieved
