Document Type and Number:
WIPO Patent Application WO/2020/161831
Kind Code:
A1
Abstract:
This power conversion device (5) comprises: a connector for connection to a storage battery (9); a converter (7) which bidirectionally converts a DC voltage of the storage battery (9) and a DC link voltage; an inverter (10) which bidirectionally converts the link voltage and an AC voltage of a system power supply (14); a control circuit (8) which controls the converter (7) and the inverter (10); and a control power supply (6) capable of supplying electric power to the control circuit (8) and the converter (7). The converter (7) includes a plurality of converter units (7a) that can be simultaneously driven in parallel. The control circuit (8) is characterized by stopping the operation of a part of the plurality of converter units (7a) and outputting a voltage to the connector, when performing an insulation test with the storage battery (9).
