Title:
POWER CONVERSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/117192
Kind Code:
A1
Abstract:
This power conversion device is provided with: a power conversion circuit that is provided with a DC terminal connected to a solar battery panel and an AC terminal connected to an AC power system and that converts DC power generated on the solar battery panel into AC power and supplies the AC power to the AC power system; a current detection means for detecting DC current flowing between the solar battery panel and the power conversion device; and a control circuit that is provided with a power generation mode for controlling the power conversion circuit so as to output active power generated from the DC power generated on the solar battery panel to the AC power system and a reactive power compensation mode for controlling the power conversion circuit so as to output reactive power to the AC power system and that switches a mode between the power generation mode and the reactive power compensation mode on the basis of the magnitude of the DC current detected by the current detection means.
