A control device of an electric compressor is provided with: a detection unit for detecting the ripple voltage of the electric compressor which is driven by a battery; a determination unit for determining whether or not the value of the ripple voltage is greater than or equal to a predetermined threshold value; and a control unit for reducing the rotation speed of a motor of the electric compressor down to a predetermined first target rotation speed greater than 0 when the value is greater than or equal to the threshold value.

Abstract: Provided is a method for determining the generation source of ripple voltage when abnormal ripple voltage is detected. The control device is for an electric compressor, the control device comprising: a detection unit that detects ripple voltage; a judgment unit that judges whether the ripple voltage is abnormal based on the value of the ripple voltage; and a cause determination unit that determines whether the cause of the abnormality is the electric compressor or some other external device, based on the control result of the electric compressor.
