现今世界各国的UPS制造及运行原理基本相同,对于在线式UPS都是由整流器、逆变器、蓄电池及静态旁路等几个部分构成。所不同的在于功率器件的选型及调制技术不同,故而造成不同品牌UPS在性能上存在一些差异,不论UPS有何区别,其主要作用就是稳定市电的波动及在市电故障晃电的情况下,不间断地提供稳定的电源。对其考核的指标主要是稳定性及可靠性。
Nowadays in the world, the UPS manufacturing and operation principle are basically the same. For the on-line UPS, there are several parts such as rectifier, inverter, battery and static bypass. The difference lies in the selection of power devices and modulation technology is different, resulting in different brands of UPS performance there are some differences, no matter what the difference between UPS, its main role is to stabilize the fluctuations in mains and Akira electricity in the case of mains failure Under, uninterrupted to provide a stable power supply. The assessment of its indicators are mainly stability and reliability.
