一种优化同步整流AC/DC变换器的应用研究
On Application of an Optimized Synchronous Rectification AC/DC Converter
摘要
Abstract
The research trend of high efficiency power supply is the zero current switch (ZCS) and zero voltage switch (ZVS) for synchronous rectifier (SR). In this thesis,the SR principle of ZCS of flyback topology is analyzed to show the relationship between true zero current detecting and ZCS synchronous rectification. Then, a theory calculation is used to deduce the optimizing efficiency. Finally,NCP4303 is utilized to show its controlling implement, and the circuit is tested.关键词
