Abstract
An object of the present invention is to achieve stable inverter control by means of current detection using one current sensor in all of periods in which overmodulation control is performed. An inverter controller includes a γ-axis current calculation section that holds, in advance, a γ-axis current arithmetic expression including a direct current as a parameter, and calculates a γ-axis current using a direct current detected by a current sensor for the γ-axis current arithmetic expression.
