摘要
科学地选择UPS设备的类型、容量、冗余方式对于提高供电系统的可靠性具有重要的意义。文章通过图表分析、公式计算等详细阐述了UPS单机组成n＋1、1＋n、n＋m冗余并机系统的可靠性以及服务器电源冗余供电的可靠性，分析了两套1＋1冗余并机系统给服务器双电源供电和双路总线零切换给服务器单电源供电的高可靠性设计方法，可供设计者参考。
It is impotrant to choose the type,capability and redundancy manner of the UPS to improve the reliability of the power system.This paper introduces the reliability of the n＋l,l＋n,n＋m redundanty parallel system assembled by single UPS as well as the reliability of the redundant power supply for the server through charts and formulas,and also analyses two of the 1＋1 redundant parallel systems for the server＇s double power supplies and the high reliable design of the dual bus zero switch for server＇s single power supply,which could be refered by the designer.
