.3.3毕业设计（论文）说明书摘要随着计算机技术、网络技术、通信技术的发展，国民经济、国防军工、政府部门的各个领域要保障计算机信息网络系统的安全、可靠运行，就离不开UPS不间断电源，这已成为信息业界乃至各行各业的共识。根据UPS不间断供电的原理，本文以提高UPS的可靠性为基本点，从UPS电源装置的结构和形式来考虑其设计方案。整个UPS主电源装置由整流/充电器、逆变器、静态旁路、维修旁路等部分组成。整流/充电器(包括蓄电池)为UPS提供在线工作的能量输入；逆变器为UPS提供在线工作的高质量的稳压稳频的交流电输出；静态旁路为UPS在整流/充电器或者逆变器故障情况下提供旁路工作电源，逆变器供电和静态旁路供电之间可实现不间断供电切换；维修旁路为UPS定期检修或故障维修时提供旁路电源。基于电源技术的高频化、模块化、数字化、绿色化的发展方向，本文结合现代电力电子技术以及信息处理技术的最新发展，利用微机作为控制核心，研究和开发大功率(10kVA以上)在线式智能UPS不间断电源。关键词：不间断电源微机控制电力电子技术智能化I******毕业设计（论文）说明书ABSTRACTWiththedevelopmentofthecomputertechnology,thenetworktechnology,communicationtechnology,inallthefieldsofthenationaleconomy,nationaldefenseandwarindustry,governmentministries,theymustdependonUPS(UninterruptiblePowerSystem)BytheprincipleofUPS,thispaperconsidersthedesignschemefromitsstructureandformatforincreasingitsreliability.Themainpowerdeviceismadeupofrectifier,charger,inverter,staticbypass,maintenancebypass.Rectifierandcharger(includingstoragebattery)offertheenergyinputofUPSwhenitisonline.InverterofferstheCVCF(ConstantVoltageandConstantFrequency)ACoutputwhenUPSisonline.Staticbypassoffersonlinebypasspowersupplywhenrectifier,charger,orinverterresultsinfaults,andtheswitchingbetweeninverterandstaticbypassisnotinterruptible.MaintenancebypassoffersbypasspowersupplywhenUPSneedsrepairingorMaintaining.Basedonthedevelopmenttrendofhigherfrequency,modularization,digitalization,andgreennessforpowertechnology,thispaperisrelevanttotherecentdevelopmentofmodempowerelectronicstechnologyandinformationprocessingtechnology,andhasstudiedtheabovemiddlecapacity(Above10KVA)onlineintelligentUPS,usingmicroprocessorascorecontrol.Keywords:UPSControlbymicroprocessorPowerElectronicsTechnologyIntelligentII******毕业设计（论文）说明书录第一章概述„„„„„„„„„„„„„„„„„„„„„„„„11.1UPS的发展„„„„„„„„„„„„„„„„„„„„„„11.1.1UPS的发展历程„„„„„„„„„„„„„„„„„11.1.2UPS的发展前景„„„„„„„„„„„„„„„„„31.2本课题研究的目的和意义„„„„„„„„„„„„„„„41.3本课题的任务和要求„„„„„„„„„„„„„„„„„51.3.1本课题的任务„„„„„„„„„„„„„„„„„„5
