不间断电源(UPS)是计算机、通信系统以及要求提供不能中断场合所·须的一种高可靠、··能的电源。交流市电输入经整流器变成直流,一部分能量给蓄电池组充电,另一部分能量经逆变器变成交流,经转换开关送到负载。为了在逆变器故障时仍能向负载提供能量,另一路备用电源通过电源转换开关来实现。
现代UPS普遍了采用脉宽调制技术和功率M0SFET、IGBT等现代电力电子器件,电源的噪声得以降低,而效率和可靠性得以提高。微处理器软硬件技术的引入,可以实现对UPS的智能化管理,进行远程维护和远程诊断。
在线式UPS的·大容量已可作到600kVA。超小型UPS发展也很迅速,已经有0.5kVA、lVA、2kVA、3kVA等多种规格的产品。
