  "textContent": "An inverter control device including: an inverter 6 configured to convert direct-current power inputted from a direct-current power supply into alternating-current power, and to supply the alternating-current power to a motor; a command value calculation unit (1, 2, 3) configured to calculate a command value of an alternating-current voltage outputted from the inverter 6, on the basis of a detection value of an alternating current; a phase compensation unit (16) configured to compensate for the phase of the command value or the phase of the detection value; an inverter control unit (4) configured to control the inverter 6 on the basis of any of the command value and the detection value compensated for by the phase compensation unit; and a motor rotational velocity detection unit (9, 14, 11) configured to detect a rotational velocity (É) of a motor 8. The phase compensation unit (16) calculates a phase lead amount (¸) on the basis of the rotational velocity (É) and the phase compensation time (t pm ) set for obtaining a predetermined phase margin, and compensates for the phase based on an inherent characteristic of the motor in accordance with the phase lead amount (¸).",
