摘要： 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
摘要翻译：要解决的问题：提供一种小型化的存储装置，更长的使用寿命和较低的环境负荷降低维护成本。解决方案：如果第一电力转换器（11）由于停止或电压沉降而停止其输出，例如，提供给输入端子（13）的AC电力的至少10％的下降，则第一用第二功率转换器（12）将电容器（C1）转换成规定的电压以输出。当需要高于第一电容器（C1）的输出电流的电流时，从第二电容器（C2）输出电流。对需要来自第二电容器（C2）的大电流的负载进行电流供给，因此第一或第二功率转换器（11）或（12）不需要大容量，从而使装置小型化。不使用重金属可以减轻环境负荷，有利于环保。此外，电容器的使用寿命为10〜15年，比电池使用寿命长，从而实现维护成本的降低。版权所有（C）2006，JPO＆NCIPI
