摘要： The inverter control device 10 controls the inverter 2 that generates the three-phase alternating current 200 for driving the AC motor 1. The PWM controller 12 executes the PWM control based on the torque command value TrqRef of the AC motor 1 to cause the inverter 2 to generate the three-phase alternating current 200. The one-pulse controller 13 executes one-pulse control based on the torque command value TrqRef to cause the inverter 2 to generate the three-phase alternating current 200. The switching controller 14 alternately switches the PWM control and the one-pulse control in the switching period for switching the control of the inverter 2 from the PWM control to the one-pulse control and controls the PWM controller 12 and one-pulse controller 13 so that one-pulse control is executed after the switching period has elapsed.
