Title:
AC ROTATING ELECTRIC MACHINE CONTROL DEVICE AND ELECTRIC POWER STEERING CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/143121
Kind Code:
A1
Abstract:
An AC rotating electric machine control device has: an AC rotating machine having m sets of n-phase windings; a current detector; a power converter; and a control unit for calculating a voltage command on the basis of the difference between a current command for the AC rotating machine and a current detection value detected by the current detector and comparing an applied voltage calculated on the basis of the voltage command with a carrier wave signal to output an on/off signal to the high-potential and low-potential side switching elements of the power converter. When detecting currents flowing through the n-phase windings on the basis of the currents flowing through current detection resistance elements inserted in series with the low-potential side switching elements, the current detector obtains the current detection values at two or more fixed timings in one cycle of the carrier wave signal.
