  "textContent": "An inverter control device includes a PWM control unit that generates a PWM pulse for controlling an inverter , and a pulse edge control unit that performs pulse edge control for correcting (shifting) a phase of a pulse edge of the PWM pulse generated by the PWM control unit . The PWM control unit generates a PWM pulse by using a modulation rate based on a voltage command (Vd*, Vq*). The pulse edge control unit corrects the PWM pulse so that a phase difference between a zero cross point where the modulation wave changes across 0 and a pulse edge of the PWM pulse falls within a predetermined range.",
