摘要
介绍一种双管反激的电路拓扑 ,分析了其工作原理 ,给出了一些关键技术参数的计算公式 ,设计并研制成功的 3 0W 3 80VAC 5 0Hz / 5 10VDC / +15 .1VDC ( 1A)、+5 .2VDC ( 2A)辅助开关电源具有功率密度高、变换效率高、可靠性高等优良的综合性能。
A new topology for double switch flyback converter is introduced.The operation principle is analyzed and some for mulas for calculating key parameters for the topology are presented. The designed and produced auxiliary switching power supply,i.e.30 W 380 VAC 50 Hz/ 510 VDC /+15.1 VDC(1 A)?+5.2 VDC(2 A),has excellent comprehensive performances such as high power density ,high conversion efficiency and high reliability.This converter has important application value for high input voltage.
