摘　　要：介绍了一种实用的大电流输出矿用本安电源,给出了工作原理、系统整体组成及工作过程,并详细论述了系统各部分的设计;电源正常工作时输出电压18 V,电流1.2 A,满足了煤矿工作面自动化系统对大电流本安电源的需求。This article introduces a practical high current output mine -used intrinsically safe power, gives the working principle, system composition and working process of the power, and every part of system designs is discussed in detail. Its output voltage is 18 V and the current is 1.2 A, and this intrinsically safe power could meet the high current power supply requirements of automation system in the coal mine working face.
