Abstract
An inverter control device 200 includes a PWM control unit 220 that generates a PWM pulse for controlling an inverter 100, and a pulse edge control unit 250 that performs pulse edge control for correcting (shifting) a phase of a pulse edge of the PWM pulse generated by the PWM control unit 220. The PWM control unit 220 generates a PWM pulse by using a modulation rate based on a voltage command (Vd*, Vq*). The pulse edge control unit 250 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.
