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

Be to solve local junction circuit interrupt or harmfully influence that the trend change of the times is given rise to to computer etc load, and secondly will pledge the sine wave to send out the high quality.Therefore 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 in common use stores up the ability ) that contains to store up the ability, and becoming the permanent pressure that the ware is the major component with contrary, the permanent frequency power equipment is chiefly used to the computer, the power supply of section between computer network system or others' electric power equipment provides not.

Occurring interrupt etc when the local junction circuit during circumstances, UPS's immediately electric energy with the battery by way of contrary becomes the method changed and continues supplying power to the load, and making the green work of load keeping, and protects the load, the hardware is not received damaging.
The UPS is one kind provides not being disconnected to the load, the high

１.１ UPS的特点及分类
1.1.1 UPS的定义及特点
UPS的英文全称是Uninterruptible Power System，意为不间断电源系统，既一种能为负载提供连续电能的供电系统。它的产生完全是当代社会计算机技术，信息技术以及相关产业飞速发展的必然结果。随着计算机在各行各业中的广泛应用，越来越多的重要数据，图象和文字要由计算机来处理和存储，如果突然停电，计算机内部随机存储器中的数据和程序就会丢失或损坏，将给工作代来许多的麻烦。同时，电网中的一些强脉冲尖峰，高能电浪涌等干扰也会引起计算机的误操而造成不必要的损失。另外，计算机内部的滤波电容放电只能维持计算机工作8~10ms的时间，如果超过这个时间，计算机就会进入自检重启状态。为了避免出现这种情况，必须设计一种电源系统，它能在停电后10ms以内恢复对负载的供电，这就是今年来出现并广泛应用的UPS系统。UPS作为计算机的重要外设，已从最初的提供后备时间的单一功能发展到今天提供后备时间及改善电网质量的双重功能，在保护计算机数据、改善电网质量、防止停电和电网污染对用户造成危害等..
