Title:
UNINTERRUPTIBLE POWER SUPPLY DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/183147
Kind Code:
A1
Abstract:
This uninterruptible power supply device is provided with: a converter (4) that converts alternating current power into direct current power, said alternating current power being supplied from an alternating current power supply (51); an inverter (7), which converts, into alternating current power, the direct current power generated by the converter or direct current power of a storage battery (52), and which supplies the alternating current power to loads (53, 54); and a control circuit (14) that controls the inverter. In the cases of starting up the inverter, the control circuit gradually increases a voltage value (V) and a frequency (F) of an output voltage (VO), while maintaining the rate of the voltage value to the frequency at a fixed value (K).
