Title:
POWER CONVERSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/085346
Kind Code:
A1
Abstract:
A power conversion device (20) is applied to a power supply system (100) including a first battery (11) and a second battery (17) having a different rated voltage from that of the first battery. The power conversion device (20) is provided with: an electrical charging circuit (30) that converts AC power input from an AC power supply (200) into DC power and that electrically charges the first battery with this DC power; a transformation circuit (40) that transforms the supply voltage of the first battery and that outputs the transformed voltage to the second battery; and a shut-off unit that, when the first battery is electrically charged by the electrical charging circuit, can shut off the supply of the DC power to the transformation circuit.
