An inverter control device is equipped with an inverter and a command value calculation unit calculates command values for the alternating current voltage output from the inverter. A phase compensation unit compensates the phase of the command values or the phase of the detected values. An inverter control unit controls the inverter on the basis of the command values or detected values that have been compensated by the phase compensation unit. A motor rotational velocity detector detects the rotational velocity of a motor. The phase compensation unit calculates the phase lead amount on the basis of a phase compensation time that is set for the purpose of obtaining a prescribed phase margin and on the basis of the rotational velocity and, in accordance with the phase lead amount, compensates the phase that is based on the specific characteristics of the motor.
