  • Publication number: 20130257335
    Abstract: A method and a circuit system for operating an electric machine are presented. The method is carried out in particular in a starting phase, a current being limited using a controllable resistor, the controllable resistor being implemented by at least one semiconductor switch, which is controlled using a clocked signal, and the signal being set in such a way that in shutdown phases, the at least one semiconductor switch is not completely shut down.

  • Patent number: 8450860
    Abstract: A power switch component having a semiconductor switch and a contacting applied to a contact zone of the semiconductor switch is introduced. The contact zone has a semiconductor layer and a metal plating applied to the semiconductor layer. The semiconductor layer has at least one conducting region and at least one non-conducting region situated directly under the metal plating.

  • Publication number: 20120306528
    Abstract: An electrical circuit device includes a semiconductor component which has power terminals and a control terminal electrically insulated from the power terminals, for applying a control voltage, and a control terminal contact surface for contacting the control terminal for measuring the electrical behavior of the semiconductor component. A connection device is provided, via which the control terminal is electrically connectable to a series device, the connection device being transferable from a nonconductive state into a conductive state, in which the control terminal is connected to the series device.

  • Publication number: 20090140388
    Abstract: A semiconductor emitter structure for emitting charge carriers of a first conductivity type in a base volume of a second conductivity type material neighbored to the emitter structure in a vertical direction, includes multiple emitter volumes of first conductivity tape material having a predetermined lateral dimension in a lateral direction perpendicular to the vertical direction. The emitter volumes are, in the lateral direction, neighbored by semiconductor volumes of second conductivity type material, wherein the predetermined lateral dimension is such that space charges created by second conductivity type carriers laterally diffusing into the emitter volumes from the semiconductor volumes limit a maximum density of first conductivity type carriers within the emitter volumes by more than 20% as compared to emitter volumes of the same lateral dimension not neighbored by semiconductor volumes of the second conductivity type material.
