摘要

UPS（Uninterruptible Power System ），即不间断电源，是一种含有储能装置，以逆变器为主要组成部分的恒压恒频的不间断电源。主要用于给单台计算机、计算机网络系统或其它电力电子设备提供不间断的电力供应。当市电输入正常时，UPS 将市电稳压后供应给负载使用，此时的UPS就是一台交流市电稳压器，同时它还向机内电池充电；当市电中断（事故停电）时，UPS 立即将机内电池的电能，通过逆变转换的方法向负载继续供应220V交流电，使负载维持正常工作并保护负载软、硬件不受损坏。UPS 设备通常对电压过大和电压太低都提供保护。

电力电子技术的应用范围已经深入到我们呢的日常生活中去了，其中UPS 不间断电源就是其中的重要应用范围。此次电力电子课程设计中，对UPS电源的设计就是本次设计的主要内容。随着UPS的广泛使用，在现代社会中的重要性越来越强，使用范围越来越广，目前，UPS在电力电子产品中已占市场相当大的份额，所以这次课程设计对我来说具有非常的实际意义，能从中让我学习许多先进的知识和理论，将所学的知识进行升华，这将有利于我今后的工作。

Abstract

UPS (Uninterruptible Power System), namely the uninterruptible power supply, is a kind of energy storage device, uninterruptible power supply voltage and frequency of the main part of the inverter. Mainly used for power supply to a single computer, computer network system or other power electronic equipment to provide uninterrupted. When the power input is normal, UPS city electricity voltage supply to load, the UPS is an AC voltage regulator, at the same time it also to the machine battery charging; when the power outage (outage), UPS will immediately built-in battery power, continue to supply 220V alternating current to the load by the method of inverse transformation, the load to maintain the normal work and protect the load of soft, hardware damage. UPS devices are often large and the voltage is too low to provide protection for all voltage

Application of power electronic technology has penetrated into our daily life in London, where UPS uninterruptible power supply is one of the important applications. Power electronics course this design, design of UPS power is the design of the main content. With the wide use of UPS, in the modern society is becoming more and more strong, used, currently, UPS has accounted for a large share of the market in electric and electronic products, so the curriculum design has practice meaning to me, let me learn a lot from the advanced knowledge and theories, to learn the knowledge of sublimation, which will be helpful for our future work.

Keywords: energy storage inverter uninterruptible power supply voltage to the load power supply
