ups不间段电源
摘要
随着微型计算机应用的日益普及及信息处理技术的不断发展,对电网供电质量提出了更高的要求。一是要解决市电中断或时变对计算机等负载产生的不良影响,二是要保证输出优质的正弦波。因此,引入了一种新型的比间断电源技术(Uninterruptible Power System,简称UPS)。
UPS是一种含有蓄能的装置(常用蓄电池蓄能),以逆变器为主要组成部分的恒压,恒频电源设备,主要用于给计算机,计算机网络系统或其他电力设备提供不间段的电力供应。当市电正常时,UPS将市电整流通过逆变器或直接稳压后供给负载使用,此时,UPS就是一台交流稳压器,同时还向机内的蓄电池充电。当市电发生中断等情况时,UPS立即将电池的电能通过逆变转换的方法向负载继续供电,使负载维持正常的工作,并保护负载,硬件不受损坏。
UPS是一种向负载提供不间断,优质,高效,可靠的交流电能,并且具有保护和监视监控功能的供电设备。UPS对于计算机及其网络,通信,金融,电力,交通,国防及高等院校,科研院所等部门的供电起着关键的作用。

Abstract
The increasingly popularization reaches constantly developing of information processing technology along with what the puter was applied, and the power supply quality was put forward the higher requirement to the work. Be to solve local junction circuit interrupt or harmfully influence that the trend change of the times is given rise to puter etc load, and secondly will pledge the sine wave to send out the high it is new than being disconnected the power supply technology ( Uninterruptible Power System, is called for short UPS) to lead one kind.
UPS is the one kind of device ( storage battery mon use stores up the ability ) that contains to store up the ability, and ing the permanent pressure that the ware is the ponent with contrary, the permanent frequency power equipment is chiefly used to puter, the power supply of section work system or others' electric power equipment provides not. When the local junction circuit often, supplying the load use
after UPS passes through the local junction circuit rectification against es the ware or directly the steady pressure, this moment, UPS is one Taiwan AC voltage regulator, and the at the same time still storage battery to the machine is charged. Occurring interrupt etc when the local junction circuit during circumstances, UPS's immediately electric energy with the battery by way of contrary es the method changed and continues supplying power to the load, and making the green work of load keeping, and protects th
