Actuators operating device for electromagnetic valve actuation in

A power module for the control of electric motors is described which displays an integrated design and provides the following functional units: A power unit with a circuit arrangement on the upper side of a substrate with power semiconductor components. A cooling unit with a cooling medium flowing through it, which has a heat sink with structured surface formed as an insert section onto which the underside of the substrate is directly fitted. A control unit with semiconductor components arranged on a carrier, which is arranged in parallel to and at a given distance from the substrate of the power unit. Contact pins between the substrate of the power unit and the carrier of the control unit for the connection and contacting of the circuit arrangement of the power unit with the semiconductor components on the control unit. A housing body, which encloses the power unit and the control unit. Two conductor bars which are led parallel to the substrate of the power unit and the carrier of the control unit and out through the housing body for the power supply to the circuit arrangement of the power unit. Connecting bars, which are led out of the housing body and connected to the circuit arrangement of the power unit and/or the semiconductor components of the control unit, for the application of control signals for the control of the power module and/or to tap off output signals from the power module.
