A power electronics module includes a capacitor having a trough-shaped housing and at least one capacitor winding. An electronic unit includes a base on which the capacitor is mounted. A cooling plate in thermal contact with a cooling surface of the capacitor is formed by a bus bar. The cooling plate is on the base of the electronic unit.

Power capacitor

A power module includes at least one carrier body for mounting at least one power component thereon, and at least one energy storage component. For this purpose, a hybrid circuit is arranged as a thick film circuit on at least one of the carrier bodies, and the hybrid circuit includes at least one thick film resistor as a discharging resistor for discharging the at least one energy storage component. The power module is adapted for use as a power converter for electric motors.

Power module

A power module is suggested having a simple and cost-effective arrangement and ensuring a reliable operation. To this end, a circuit arrangement comprising at least one electronic component is arranged on a carrier body. A conductor pattern is formed on the top side of the carrier body, and a structured cooling element made of the material of the carrier body, is provided on the bottom side. The invention also relates to a power module as power converter for electric motors.

An electric drive unit includes an electronic control and monitoring module integrally connected to an electric motor. The housing of the electric motor has a double-walled construction to form a water jacket with cooling water passages therein. The electronic module includes at least one high power component that requires cooling. This component is mounted directly on a cooling insert that extends through a recess in the electronic module housing and is inserted in an opening provided in the outer wall of the motor housing. In this manner, the cooling insert is integrated into the water jacket of the motor housing and is directly cooled by the cooling water flowing in the cooling passages. A very compact and reliable construction is achieved, in which the electric motor and the electronic module share a common water cooling circuit. External water hoses and external electrical connections between the electric motor and the electronic module are avoided.

Integrated electric drive unit including an electric motor and an electronic control and monitoring module

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.

Power module for the control of electric motors

The object of the patent application is an electronic control unit with triggering and power components, in particular an ignition control unit, whose electronic circuit comprises various assemblies in hybrid technology. To reduce the assembly expenditure and costs for manufacture, while at the same time reducing the volume, the invention provides for the assemblies of the electronic circuit to be integrated in a hybrid circuit and arranged on a single common carrier element. This carrier element is designed as an electrically non-conductive ceramic carrier of Al.sub.2 O.sub.3, by which the electronic circuit of the control unit is electrically insulated from a heat sink.
