Japanese Patent JP7209582
Kind Code:
B2
Abstract:
To obtain an uninterruptible power supply system which can mutually utilize power accumulated in a battery among a plurality of uninterruptible power supply devices while suppressing output power of an inverter.SOLUTION: An uninterruptible power supply system 100 comprises: a plurality of uninterruptible power supply devices 11, 12, 13. The plurality of uninterruptible power supply devices 11, 12, 13 comprise: converters 111, 112, 113; inverters 121, 122, 123; batteries 131,132, 133; and control parts 201, 202, 203. The control part 201 of at least one uninterruptible power supply device 11 of the plurality of uninterruptible power supply devices 11, 12, 13 causes the converter 111 to convert DC power of the battery 131 into AC power and causes the converter 111 to supply the converted AC power to one or more other uninterruptible power supply devices 13 in a state in which supply of the AC power from an AC power supply 3 is stopped.SELECTED DRAWING: Figure 7
