1 静止变换式UPS的概况近年来UPS市场发展迅速,除了旋转发电机式外,各行各业用的最多的就是静止变换式UPS。随着IT、IDC技术的发展,带动了各行各业中局域网、广域网和互连网的普遍实施,多数单位有了自己的网站,各系统也建立了自己的网络,系统之间又形成了互连网等等。随之,对系统可靠性的要求就提高了,电源是系统可靠性的基础,于是各种容量的UPS都有了用武之地。为了进一步提高电源的可靠性,不少系统采用了N+X并联冗余方案。
1 static conversion UPS Overview In recent years the rapid development of the UPS market, in addition to rotating generator, the most used in all walks of life is the static conversion UPS. With the development of IT and IDC technology, it has led to the universal implementation of LAN, WAN and Internet in all walks of life. Most of the units have their own websites, and each system has established its own network, and the Internet has formed between the systems. . As a result, system reliability requirements have increased, and power supplies have been the foundation of system reliability, so UPSs of various capacities have come into play. In order to further improve the reliability of the power supply, many systems use the N + X parallel redundancy scheme.
