Abstract
A power converter converts a DC voltage including a pulsation component into an AC voltage and outputs the AC voltage to a synchronous electrical motor. A control device for controlling the power converter includes a pulsation component detection unit and a control circuit. The pulsation component detection unit detects a pulsation component. The control circuit controls the power converter so that a load angle of the synchronous electrical motor is increased in accordance with increase in an instantaneous value of the pulsation component.
