    • In the case where there coexist general loads requiring backup only for a short duration and a specific load requiring backup for a longer duration, uninterruptible power with higher reliability is supplied to the specific load with the adoption of a simple configuration. A DC backup power supply system comprises an AC/DC converter for normally supplying DC power to loads in while (the general loads and the specific load, included), and a control circuit for supplying DC output backing up the loads in whole for relatively short time only from a battery at the time of a power outage, while supplying DC output backing up the specific load, such as a cache memory and so forth, for relatively long time. Thus, it is possible to implement an uninterruptible power supply system small in size and low in cost, provided with a function for proper use depending on a prevailing situation.
    • 在需要在短时间内需要备份的一般负载和需要较长持续时间备份的特定负载的情况下,采用简单配置向具体负载提供具有更高可靠性的不间断电源。 直流备用电源系统包括用于在(一般负载和特定负载)下正常供应直流电力的AC / DC转换器,以及用于提供直流输出的控制电路,其整体负载相对较短 在停电的时候只能从电池中提供时间,同时在相对长的时间内提供备份诸如高速缓冲存储器等的特定负载的DC输出。 因此,可以实现尺寸小,成本低的不间断电源系统,其具有根据现行情况适当使用的功能。
