一种新型UPS后备蓄电池组切换解决方案

摘要

本文提出一种新型UPS后备蓄电池组切换的解决方案，在双机并联功率均分UPS系统中，当一台UPS输出故障时，两台UPS的后备蓄电池组自动同时为负载供电，从而实现了蓄电池组实际后备时长无缩减、并联操作无安全隐患的效果。%　　This article proposed a novel switching solution of UPS backup battery .When a UPS output fault, the two UPS backup batteries automatically load supply which can achieve the effect that battery backup time without reduction, parallel operation no security risks.
