摘要： PROBLEM TO BE SOLVED: To solve problems of conventional methods: a method of mounting an engine generator as a driving power supply in case of power failure, which needed power generation output two or three times as much as that of commercial power supply from the viewpoint of a margin of characteristics peculiar to the engine generator and required an extremely large-sized engine generator; and a method of using a large-capacity battery, which needed high cost for a station, resulting in contradiction to extending communication areas by increasing as many inexpensive stations as possible. SOLUTION: This power supply unit comprises a small battery 15 connected with a DC power supply unit 14 and charged when a commercial power source 17 is supplied, and a small alternator 18 powered by an engine in case of power failure of the commercial power source 17. By operating the small alternator 18 in case of power failure, rectified DC power supply is supplied directly to a wireless device 13. Thus, a combination of the small-sized battery and the small-sized alternator can realize an uninterruptible power supply unit for an extremely small-sized mobile radio base station.

解决方案：该电源单元包括与DC电源单元14连接并在供应商业电源17时充电的小型电池15以及在商业电源发生故障的情况下由发动机供电的小型交流发电机18 电源17.通过在断电的情况下操作小型交流发电机18，整流的直流电源被直接提供给无线设备13.因此，小型电池和小型交流发电机的组合可以实现不间断电源用于极小型移动无线电基站的供电单元。版权所有（C）2004，JPO
