Title:
POWER CONVERSION DEVICE AND POWER CONVERSION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/016991
Kind Code:
A1
Abstract:
A control unit (31) of each power conversion device (21) in a power conversion system controls a switching element unit (3) on the basis of a detection value of a reactor current that flows to a filter reactor (4), a detection value of an output voltage that is output between terminals of a filter capacitor (5), and a detection value of an output current that flows through an output reactor (6). The control unit (31) generates a voltage command on the basis of the output current and the output voltage, and generates a correction amount for the voltage command on the basis of the output current from which a reference frequency component has been removed. The control unit (31) generates a current command on the basis of the additional value between the voltage command and the correction amount, and controls the switching element unit (3) so that the reactor current matches the current command.
