An inverter control device e includes a pulse width modulation (PWM) pulse generation unit that generates a PWM pulse signal for controlling an inverter in every predetermined control cycle, wherein the PWM pulse generation unit generates the PWM pulse signal to meet a pulse generation condition that at least three or more pulses exist in one cycle of a fundamental of an output voltage from the inverter and a state of the PWM pulse signal is switched between on and off at a zero crossing point at which the fundamental changes across zero while generating a PWM pulse signal asynchronous with the control cycle.
