摘　　要：针对改善多路输出反激变换器交叉调整率的问题，在详细地分析影响交叉调整率的各项因素的基础上，讨论了二极管整流以及同步整流对交叉调整率的影响问题。研究了同步整流技术对交叉调整率的改善作用，通过仿真分析和实验测试，验证了同步整流技术不仅提高了多路输出反激变换器的效率而且明显改善了交叉调整率，说明合理设计同步整流电路可以明显提高多路输出反激变换器的整体性能。Under the detailed analysis of the impact of cross-regulation on the basis of various factors, diode regulation as well as synchronous rectifier on the impact of cross-regulation in order to improved the problem of multi-output flyback converter＇s cross regulation are discussed. The effect of synchronous rectification technology to improve cross-regulation,is studied and synchronous rectification technology not only improves the efficiency of multi-output flyback converter but also improved cross regulation significantly is verified. Through simulation and experimental tests. It explained the rational design of synchronous rectifier circuit can impros the overall performance of multiple output flyback converter.
