    • PROBLEM TO BE SOLVED: To provide a storage device attaining miniaturization, reduction in maintenance cost by a longer service life, and low environmental load. SOLUTION: If a first power converter (11) stops its output due to stopping of or voltage settlement, for example, at least 10% drop in AC power supplied to an input terminal (13), the output voltage of a first capacitor (C1) is converted into a prescribed voltage with a second power converter (12) for output. When a current higher than an output current of the first capacitor (C1) is required, a current is output from a second capacitor (C2). Current supply is performed to a load requiring a heavy current from the second capacitor (C2), therefore the first or the second power converter (11) or (12) does not need large capacity, thus miniaturizing the device. No use of heavy metal provides environmental load reduction, which is advantageous in environmental protection. Furthermore, the service life of the capacitor is 10 to 15 years, which is longer than that of a battery, thus attaining maintenance cost reduction. COPYRIGHT: (C)2006,JPO&NCIPI
