Document Type and Number:
WIPO Patent Application WO/2021/045021
Kind Code:
A1
Abstract:
A rotating electrical machine (10) control device (50) is applied in a system provided with a power conversion circuit (20) electrically connected to a rotating electrical machine, and a capacitor (21) electrically connected to an input side of the power conversion circuit. The rotating electrical machine control device is provided with a determination unit which, on the basis of the operation range of the rotating electrical machine, determines a switching mode of the power conversion circuit reflecting a ripple current flowing through the capacitor, and an operating unit for operating the power conversion circuit so as to make the switching mode of the power conversion circuit the switching mode determined by the determination unit.
