Title:
AC ROTATING MACHINE CONTROL DEVICE AND ELECTRIC POWER STEERING DEVICE EQUIPPED WITH SAME
Document Type and Number:
WIPO Patent Application WO/2017/064756
Kind Code:
A1
Abstract:
Provided is an AC rotating machine control device capable of superimposing fifth- and seventh-order harmonic voltages on an AC voltage by performing arithmetic processing with a low processing load, said AC voltage being applied to an AC rotating machine, and also provided is an electric power steering device equipped with the AC rotating machine control device. When an intermediate voltage command among three-phase fundamental voltage commands (Vub, Vvb, Vwb) is larger than an oscillation center voltage, the AC rotating machine control device adds an offset value to the intermediate voltage command. When the intermediate voltage command is smaller than the oscillation center voltage, the AC rotating machine control device executes intermediate voltage offset processing for subtracting the offset value from the intermediate voltage command.
