Abstract
To provide a high-voltage apparatus control device capable of judging the connection state of a connector and discharging residual charge in a short time. A control devicecontrols an electric compressor and is provided with an interlock loopannexed to a connectorfor connecting the electric compressor to an HV battery. The control devicedetects connection/disconnection of the connectoron the basis of the state of the interlock loopand forcibly discharges residual charge in an internal smoothing capacitorwhen disconnection of the connectoris detected.
