Abstract
In a two-phase modulation type three-phase inverter control method having a pause section in which a pulse signal obtained by comparing a modulated wave signal for driving a motor and a carrier signal is not output, a pulse signal generation unit switches a first carrier signal to a second carrier signal when an electric angle of the motor is within the pause section for each of three phases.
