随着信息科学技术的飞速发展 ,各医院微机的普及率已相当高 ,因此微机的故障率也相应提高。本文介绍的微机ＡＴＸ开关电源是近几年开发的新型电源 ,与旧型号开关电源相比 ,有其独特的特点 ,结构也较复杂。由于厂家未提供电路图 ,本人根据实物绘制一份 (图略 ) ,下面作一介绍。 With the rapid development of information science and technology, the popularization rate of microcomputer in various hospitals has been very high, so the failure rate of microcomputer has also been correspondingly increased. This article describes the microcomputer ATX switching power supply is a new type of power developed in recent years, compared with the old model switching power supply, has its unique characteristics, the structure is more complicated. Because the manufacturer did not provide the circuit diagram, I draw a copy of the physical (figure omitted), following an introduction.
