Title:
DC POWER DISTRIBUTION SYSTEM AND CONTROL POWER SUPPLY GENERATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/233651
Kind Code:
A1
Abstract:
Voltage command values are set in accordance with the voltage variations of a plurality of power supply sources (1, 2, 3), and one of the outputs of a plurality of power supply circuits (21, 22, 23, 24) that output DC voltages converted in accordance with the voltage command values is supplied to a power conversion circuit (10) as a control power supply. This enables system operation to continue even at an abnormal time due to a device failure and a power outage and enables the power consumption of the control power supply to be suppressed with respect to the voltage variations of the power supply sources (1, 2, 3).
