Title:
電動機の制御装置及びそれを備えた電動車両
Document Type and Number:
Japanese Patent JP6681266
Kind Code:
B2
Abstract:
The purpose of the present invention is to reduce the number of times of switching to be performed when reducing a zero-phase current. This electric motor control device controls an electric motor, the phases of which are connected independently of one another, and has a control means which outputs a PWM control signal for controlling a voltage to be applied to the electric motor on the basis of an input torque command. The control means controls, on the basis of a zero-phase voltage command which is obtained from an alternating current of the electric motor and used for reducing a zero-phase current, the pulse width and amplitude of a zero-phase voltage consisting of the sum of output voltages.
