Abstract:
Provided is a control device of an AC motor, including: an inverter including a switching element; switching control means for controlling the switching element; and phase detection means for detecting a rotor phase of an AC motor, wherein the switching control means controls the switching element so that a voltage waveform of the inverter has half-wave symmetry in an interval of a width centering on a fundamental voltage phase of 180 deg±180 deg, the switching control means controls the switching element so that a harmonic voltage phase of the inverter becomes variable on the basis of a fundamental voltage-rotor phase difference which is a difference between a fundamental voltage phase and the rotor phase of the AC motor, and the switching control means controls the switching element so that a harmonic voltage amplitude of each order of the inverter is inversely proportional to the order.

Claim (Index 7):
The control device of an AC motor according to  claim 1 , wherein the AC motor is a drive source of an electromotive vehicle drive system, and\n the switching control means controls the switching element so that the presence or absence of the odd symmetry is switched on the basis of operation conditions of the electromotive vehicle drive system.
