ups不间断电源设计毕设论文.doc

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。 关键词： 不间断电源 电子技术  ABSTRACT With the development of the computer technology, the network technology, communication technology, in all the fields of the national economy, national defense and war industry, government ministries, they must depend on UPS (Uninterruptible Power System) By the principle of UPS, this paper considers the design scheme from its structure and format for increasing its reliability. The main power device is made up of rectifier, charger, inverter, static bypass, maintenance bypass. Rectifier and charger (including storage battery) offer the energy input of UPS when it is online. Inverter offers the CVCF (Constant Voltage and Constant Frequency) AC output when UPS is online. Static bypass offers online bypass power supply when rectifier, charger, or inverter results in faults, and the switching between inverter and static bypass is not interruptible. Maintenance bypass offers bypass power supply when UPS needs repairing or Maintaining.
