　　For best battery life, i.e. greatest number of charge/discharge cycles and years service most battery manufacturers recommend that you should aim to recharge the batteries when they have reached around 50% discharge. This level of discharge, of course, must be measured according to the rate at which the batter is discharged, which as w have already seen, varies the available total capacity of the battery.

随着电力电子学(功率电子学)的发展，为实现大功率的电能转换，于 是出现了静态UPS，它的主电路和控制电路均采用半导体器件，它也是目 前绝大多数概念中的UPS，其典型框图如图1-2所示。其基本原理是：市电 输入经整流器将交流电变成直流电，一方面给蓄电池组充电，另一方面为 逆变器提供能量，再将直流电变成交流电经转发生故障时，另一路备用电源(旁路电源)经过转换开关实现向负载供电。旁路电源市
