Title:
UNINTERRUPTIBLE POWER SUPPLY DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/026357
Kind Code:
A1
Abstract:
An AC/DC converter (42) converts an AC voltage supplied from an AC power supply (30) or an AC voltage supplied to a load (31) into a first DC power supply voltage. A power supply line (16) transmits the first DC power supply voltage to a plurality of power conversion modules (P) and a bypass module (B0). The bypass module (B0) includes: a switch (20) connected between the AC power supply (30) and the load (31); and a first control device (28) operating by receiving an operation power supply voltage based on the first DC power supply voltage and thereby controlling the on/off of the switch (20). The power conversion modules (P) each include: a power converter converting the power supplied from the AC power supply (30) or a power storage device (32) into an AC power and supplying the AC power to the load (31); and a second control device (14) operating by receiving an operation power supply voltage based on the first DC power supply voltage and thereby controlling the power converter.
