一种矿用本安电源的设计
Design for a Kind of Intrinsically Safe Power Supply
摘要
Abstract
We designed an intrinsically safe power supply.Modular isolation voltage stabilizing method is adopted and overvoltage and over-current protection is realized by analog circuit,the AC / DC voltage input range can be achieved at 9 V to 36 V,with constant output voltage of 12 V;the working current is less than or equal to 500 mA.The test results show that the load effect is only 1％,and the source effect is less than 0.4％.The overall efficiency of the power supply can reach 83％,and it can run stably and reliably.关键词
