Title:
ALTERNATING CURRENT ROTATING ELECTRICAL MACHINE CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/233682
Kind Code:
A1
Abstract:
Provided is an alternating current rotating electrical machine control device capable of suppressing a low frequency component, such as current, that occurs in a particular number of carrier signals. This alternating current rotating electrical machine control device changes a carrier cycle and/or an update cycle so that an evaluation value computed on the basis of an update cycle and a carrier signal, which is a value obtained by dividing the alternating current cycle of an alternating current voltage command value by the carrier cycle, does not match a specific value obtained by adding a component of a frequency lower than the alternating current cycle for one or more of a current, a voltage, and power supplied to a plurality of coils.
