Title:
CONTROL DEVICE FOR ROTATING ELECTRICAL MACHINE
Document Type and Number:
WIPO Patent Application WO/2019/082825
Kind Code:
A1
Abstract:
This control device (DU, DU1-DU3) for a rotating electrical machine is applied to a control system comprising: a rotating electrical machine (10) having a plurality of sets (14, 15) of multiphase winding wires wound around a stator (13); and inverters (SXH-SWL, 20) that apply a voltage to each winding wire. The control device comprises: a current detection unit (42) that detects currents flowing through the winding wires; and operation units (43-50) that operate the inverters to apply a rectangular voltage to each winding wire group on the basis of a detection value of the current detection unit. The current detection unit detects the current flowing through a target winding wire during a detection period, if the detection period is designated as a period during which the current flowing through a winding wire group does not interfere with the current flowing through the target winding wire, the winding wire group being from among the plurality of winding wire groups and not including the target winding wire for which a current flowing therethrough is to be detected.
