Title:
ROTATING ELECTRIC MACHINE CONTROL DEVICE AND ELECTRIC VEHICLE
Document Type and Number:
WIPO Patent Application WO/2019/102539
Kind Code:
A1
Abstract:
Provided are a rotating electric machine control device and an electric vehicle capable of, when one phase abnormality occurs, controlling the DC power that is input/output from a inverter to a DC power supply so as not to exceed an upper limit input/output power while allowing a rotating electric machine to output torque by controlling the currents flowing through normal two phase windings. When it is determined that one phase is abnormal, the rotating electric machine control device controls, on the basis of a current command value and detected three phase current values, the currents flowing through respective normal two phase windings and upper-limits the magnitude of the current command value so that the DC power that is input/output from a inverter to a DC power supply does not exceed a preset upper limit input/output power.
