摘要： An apparatus for connecting an electrical device to a high-voltage power grid with a leadthrough plug-in bushing which has a hollow receiving section which extends in a plug-in direction and is composed of an electrically nonconductive insulating material, wherein a metallic contact part is arranged on a closed end region of the receiving section, which metallic contact part extends through the insulating material of the receiving section or lengthens said receiving section in the direction of the closed end region. The apparatus can be assembled and serviced in a simple, quick and therefore cost-effective manner. The receiving section is equipped with a current sensor which is designed to detect an electric current flowing across the metallic contact part.

摘要： An IGBT die structure includes an auxiliary P well region. A terminal, that is not connected to any other IGBT terminal, is coupled to the auxiliary P well region. To accelerate IGBT turn on, a current is injected into the terminal during the turn on time. The injected current causes charge carriers to be injected into the N drift layer of the IGBT, thereby reducing turn on time. To accelerate IGBT turn off, charge carriers are removed from the N drift layer by drawing current out of the terminal. To reduce VCE(SAT), current can also be injected into the terminal during IGBT on time. An IGBT assembly involves the IGBT die structure and an associated current injection/extraction circuit. As appropriate, the circuit injects or extracts current from the terminal depending on whether the IGBT is in a turn on time or is in a turn off time.

摘要： A wireless, parasitically powered data processing unit 1 is fastened to a current carrying conductor 3 without additional tools, by means of a flexible ferromagnetic belt 11 that is clamped by its housing around the conductor and forms a transformer core to concentrate magnetic flux 5 produced by the conductor and provide operational power to a sensor interface 18, a data processing device 16, and a wireless transceiver 22, without the need for batteries. Sensor signals 33 received from local sensors are processed by the data processing device and information derived from the sensor signals is wirelessly transmitted to remote receivers. The sensor signals may represent measurements of the physical condition of the current carrying conductor or another electrical device, for such conditions as temperature, humidity, vibration, or noise.
