1、I UPS 电源设计 作者姓名： 专业班级： 指导老师： 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，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 UP
2、S 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。 UPS 主要分为， UPS 运行方式部分，开关电源部分和电压逆变部分，且每一部分都有其典型的控制芯片组成。 论文中的 UPS 电路简单的体现了 UPS 电源的基本功能，实现 DC-AC 的逆变过程，最终实现频率 50HZ 的 220V 交流电压输出。 关键字 ： UPS 电源，断电续用，电力电子，智能网 络化，在线式II The design of Uninterruptible Power System Abstract: Wit
