电池备份存贮系统的电源电路

The Supply Circuit for Memory System with Stand一by Battery

本文为拙着“电池供电存贮系统”一文的续篇。专门探讨电池备份存贮系统电源电路的特点。介绍了双电源供电线路的转换方法。针对两个电源转换中可能出现的不可靠因素，提出解决措施。并对常用电池充电电路作了介绍。

This is the sequel of the author’paper“The Memory System Supplied by Battery”,specifically discussing the power circuit of memeory system with stand-by battery.The switchingmethed of the bi-power circuit is recommended and the solving meassure for unreliability which oc-curs probably in switching of two power;ystem is suggested.The charge circuits in common use arealso expotinded.
