CONTROL APPARATUS FOR AC ROTARY MACHINE AND CONTROL METHOD FOR AC ROTARY MACHINE

摘要

PROBLEM TO BE SOLVED: To suppress vibration and noise during driving by stably driving an AC rotary machine with a small volume of electric power.SOLUTION: The present invention comprises a controller (101) that supplies desired electric power through a power feeding section (3) to an AC rotary machine (1) with frequency characteristics at an inductance. The controller (101) supplies electric power with such a frequency (fh) that a function including the inductance of the AC rotary machine (1) becomes an extreme value and electric power with a fundamental wave frequency to the AC rotary machine (1) through the power feeding section (3).
