Title:
CURRENT CONTROL DEVICE AND CURRENT CONTROL METHOD FOR PERMANENT MAGNET SYNCHRONOUS MOTOR
Document Type and Number:
WIPO Patent Application WO/2023/223412
Kind Code:
A1
Abstract:
A current control device (10) for a permanent magnet synchronous motor (20) outputs current to the permanent magnet synchronous motor, and comprises a plurality of current controllers (10_1, ... ,10_m) that are respectively provided for a plurality of phases (20_1, ... ,20_m) of windings of the permanent magnet synchronous motor provided with the windings of the plurality of phases, that supply current to the windings, and that are connected in parallel to each other. The current control device (10) performs control such that a component, which offsets a reverse phase current generated when an output of one current controller among the plurality of current controllers has been blocked, is superimposed on a current controller for which an output has not been blocked among the plurality of current controllers.
