摘　　要：针对煤矿井下易燃易爆的特殊环境,文章基于单端反激式变换器,设计了一种本质安全型开关电源,该电源结构简单,体积小,输入与输出电气隔离,具有多路本安输出端口,每路均设计过流过压保护。具体介绍其中一路输出18V/1A的设计。For the special circumstances of coal mine is flammable and explosive, an intrinsically- safe switching power supply is designed, which based on single-ended flyback converter. The power has features of simple structure, small volume, electrical isolation, multiple＇ output ports of the safety and over-current and over-voltage protection circuit are designed for each road. 18V/ 1A, one of the outputs is introduced in details.
