备用并联供电系统是随电子计算机的集成电路化而出现的一种高可靠直流供电系统。本文将论述PWM(注)型稳压电源并联供电的必要性、并联供电系统方案及其特点、K-n(F)系统的可靠性分析以及某大型计算机(6+1)备用并联供电系统。
Standby parallel power supply system is a highly reliable DC power supply system that appears with the integrated circuit of electronic computers. This paper will discuss the necessity of parallel power supply of PWM (Note) regulated power supply, the scheme of parallel power supply system and its characteristics, the reliability analysis of K-n (F) system and the standby parallel power supply system of a large computer (6 + 1).
