摘要： Provided is an inverter control device including: an inverter 6 configured to convert DC power inputted from a DC power supply into AC power and supply the AC power to a motor; command value calculating means for calculating a command value for an AC voltage outputted from the inverter 6, based on a detection value for an AC current; phase compensating means for compensating for a phase of the command value or the detection value; inverter control means for controlling the inverter 6, based on the command value compensated for by the phase compensating means; motor rotation speed detecting means for detecting a rotation speed of the motor 8; d-q axes non-interference voltage command value calculating means for calculating a d-q axes non-interference voltage command value to cancel out interference voltages interfering with each other between d and q axes, and for outputting the d-q axes non-interference voltage command value to the command value calculating means; and reverse phase compensating means for compensating for a phase according to the amount of compensation of the phase compensated for by the phase compensating means, in which the phase compensating means calculates the amount of phase lead based on the rotation speed and a phase compensation time set in order to obtain a predetermined phase margin, and compensates for a phase based on characteristics inherent in the motor, by the amount of phase lead, and the reverse phase compensating means compensates for a phase of the d-q axes non-interference voltage command value by the same amount of compensation as the amount of phase lead in the opposite direction to the phase compensated for by the phase compensating means.
