Title:
CONTROL APPARATUS FOR DYNAMO-ELECTRIC MACHINE, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2023/032678
Kind Code:
A1
Abstract:
This control apparatus for a dynamo-electric machine is applied to a control system comprising: a plurality of electric power conversion circuits (22a, 22b) for converting DC electric power from a DC power supply (30) into AC electric power by a switching operation and outputting the AC electric power; dynamo-electric machines (21a, 21b) that are provided so as to correspond to each of the electric power conversion circuits and are supplied with the AC electric power output by the electric power conversion circuits; and a capacitor (23) that is connected in parallel with the DC power supply and is provided at an input side of the electric power conversion circuits, the capacitor being shared by the electric power conversion circuits. The control apparatus for the dynamo-electric machine comprises: an adjusting unit for adjusting an output mode of a voltage vector to the dynamo-electric machines; and an operation unit for performing a switching operation of the electric power conversion circuits in order to output the voltage vector adjusted by the adjusting unit.
