Title:
UNINTERRUPTIBLE POWER SUPPLY DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/006427
Kind Code:
A1
Abstract:
An uninterruptible power supply device (1) receives alternating current power with a first load (53), said alternating current power being supplied from an alternating current power supply (51). The uninterruptible power supply device (1) is provided with: a converter (2) that converts into direct current power the alternating current power supplied from the alternating current power supply (51); an inverter (4), which converts into alternating current power the direct current power generated by the converter (2) or direct current power of a battery (3), and supplies the power to a second load (54); control units (15, 24, 25), which control reactive power generated by the converter (2), and compensate at least a part of reactive power generated by the first load (53); and a limiter (13) that limits the reactive power generated by the converter (2) to be equal to or lower than upper limit power. The upper limit power is set to a value corresponding to a difference between the rating capacity of the uninterruptible power supply device (1) and the alternating current power to be supplied to the second load (54).
