摘 要
不间断电源在一些关键性的负载如:计算机、通信系统、医院等中扮演重要的
角色。它们在市电正常或故障情况下均为负载提供可靠、干净的电源。在各种UPS中，在线UPS具有最好的性能，为负载提供了最多电源故障保护。然而传统的在线UPS有多个功率部分和模拟控制器，是一个非常复杂、昂贵的系统。因此，适合现代科技发展的高质量、高可靠性全数字UPS不间断电源的研究就成为人们十分关注的课题。
本文介绍了一种基于8096控制芯片的在线式（5KV）UPS电源。利用8096芯片的高运算能力以及专门用于控制领域的丰富的外设，将在线式UPS的PWM专用控制芯片及其外围电路还有数字控制所需的微处理器功能都集成到一块芯片中，这样大大的增加了电路的集成度，减少了成本。整个UPS的控制以全数字化方法实现，包括SVPWM波形的产生、输出频率和相位的跟踪以及PD控制算法等。
本论文是在参阅了国内外大量资料和UPS最新发展技术的基础上进行的国内中型功率UPS开发和研制的一次有益的尝试和探索，从各个功能实现的局部
电路到整个系统对本系统的工作原理做了较详细的分析，整个系统经试验调试，各项性能指标和功能均达到了预期的目标和要求。

Abstract
Uninterruptible power supplies (UPS) play a key role in infecting critical loads, such as computers, commendation system, and medical system. They can provide reliable and pure power supply for loads neither power good or not. Among the various UPS topologies on-line UPS provides the most protection to such loads against any utility power supply. However, the old on-line UPS includes many power Parts and analogy controllers, it has been one of the most complex and expensive type of system. Therefore, the study of high quality and reliability full digital UPS (Uninterruptible Power Supply), which fits the development of modem science and technology has become an attentive problem.
This Paper described the middle/high-power (5kVA) on-line UPS, Which was based on 8096 control chip, which is a kind of 8096 of TI Company. For 8096 controller is high CPU bandwidth and peripherals specifically chosen for control application, we integrate PWM controllers,
