摘要:
Proposed is an integrated drive element (110) which is particularly suitable for use in an automatic shift transmission of a motor vehicle. The integrated drive element (110) has at least one electric motor (112), with preferably precisely two electric motors (112) being provided which can be used for example for a dual-clutch transmission. Also provided is at least one electronic engine control unit (114) which is designed for controlling the functionality of the at least one electric motor (112). Said electronic engine control unit (114) in turn has a housing (116). The at least one electric motor (112) spatially directly adjoins the housing (116) and/or is at least partially integrated into the at least one housing (116).

The invention relates to a method and to a device for supplying an electric consumer with direct current, preferably an electric motor, which can be electronically commuted by means of a semi-conductor power output stage. The consumer current thereof, corresponding to the decline in voltage, is determined on a reference resistor. The decline in voltage on one part (30) of the electric circuit (24) of the consumer or on the consumer (10) is automatically used as a measuring variable, and subsequently, said decline in voltage is adjusted, by temperature compensation, to the value of the decline in voltage on a reference resistor having a very low thermovoltage.

Le dispositif proposé est utilisé pour faire fonctionner une lampe à décharge (10). Il comporte un transformateur de tension (19), de préférence un transformateur inverse. Ce dernier est raccordé, à sa sortie (20) à un circuit en pont (12) dont la diagonale (11) contient la lampe (10). Au voisinage de la lampe (10) est disposé un élément conducteur (31) de telle façon qu'un champ électrique (32) puisse se produire entre la lampe (10) et l'élément (31). Ce dernier est raccordé à la borne (27, 28) de la sortie (20) du transformateur de tension (19), laquelle présente le potentiel positif par rapport à l'autre borne (27, 28).

The invention relates to a drive device with an electric motor (3) and drive electronics (2) for the electric motor (3), with the drive electronics (2) being arranged on a circuit mount (1). The invention provides for the circuit mount (1) to be a mechanical component (12) or part of a mechanical component (12) of the electric motor (3).
摘要:
The invention relates to a power semiconductor module which comprises a stack of carrier substrates that are arranged in layers and one on top of the other and that are provided with at least one strip conductor on at least one main surface. At least one electronic semiconductor component is arranged between two adjacent carrier substrates of the stack. The semiconductor component is electrically contacted to at least one strip conductor of a carrier substrate that is arranged in the stack over the semiconductor component and to at least one additional strip conductor of a carrier substrate that is arranged in the stack under the semiconductor component and in such a way that heat is conducted. The aim of the invention is to provide improved heat emission and a construction that is as compact as possible at the same time. To this end, the two outer carrier substrates of the stack are configured as an upper and a lower wall of a closed housing component which surrounds the at least one semiconductor component. The gaps between the stacked carrier substrates are sealingly closed by means of a circulating wall that is fixed to the carrier substrates.

The proposal is for a device for igniting gas discharge lamps (10, 11) by means of a high-voltage pulse in which one high-voltage generator (16) is allocated to a plurality of lamps (10, 11). The high-voltage generator (16) is connected to the gas discharge lamps (10, 11) to be ignited via high-voltage switching components (14, 15). The high-voltage switching components (14, 15) preferably take the form of radiation-triggered four-layer diodes.
