Patent number: 7621494Abstract: The disclosure specifies a fixing device for a current sensor, which fixing device comprises a holding element which is shaped in the manner of a U and a surface part which is connected to the free end of a limb of the holding element, with the surface part being arranged substantially perpendicular to the connected limb and extending away from the opening in the holding element. The fixing device also comprises a retaining element which is connected to the surface part and is shaped in the manner of a C, with the orientation of the opening in the retaining element corresponding substantially to the orientation of the opening in the holding element. By means of the fixing device for a current sensor, mounting can be simplified, carried out more quickly and performed in a manner which is less susceptible to faults.Type: GrantFiled: January 16, 2008Date of Patent: November 24, 2009Assignee: ABB Schweiz AGInventors: Jochen Rees, NĂ¼rten Halavart

Patent number: 6040988Abstract: A converter with a DC voltage intermediate circuit and including a rectifier circuit having an AC voltage input and a DC voltage output, which rectifier circuit can be connected to a power supply system, an invertor circuit having a DC voltage input and an AC voltage output, and a DC voltage intermediate circuit, which is arranged between the DC voltage output of the rectifier circuit and the DC voltage input of the invertor circuit. Also included is two connecting lines, leading from the DC voltage output of the rectifier circuit to the DC voltage input of the invertor circuit, and at least one intermediate circuit capacitor arranged between the connecting lines. A simplified structure is achieved by virtue of the fact that in order to protect the converter in the event of a short circuit, a first controllable semiconductor switch is arranged in at least one of the connecting lines between the DC voltage output of the rectifier circuit and the at least one intermediate circuit capacitor.Type: GrantFiled: August 25, 1998Date of Patent: March 21, 2000Assignee: Asea Brown Boveri AGInventors: Jochen Rees, Jurgen Steinke

Patent number: 5969959Abstract: A converter circuit arrangement is specified having a rectifier, an intermediate circuit and an invertor connected thereto. In order to protect the circuit against failures and overvoltage, a protection circuit which comprises, in particular, varistors is connected between the two partial rectifiers of the rectifier.Type: GrantFiled: August 18, 1998Date of Patent: October 19, 1999Assignee: Asea Brown Boveri AGInventors: Bjorn Odegard, Jochen Rees

Patent number: 5835362Abstract: In order to reduce the commutation inductance of series-connected controllable semiconductor components (V1-V6), the latter are connected, in an essentially orthogonal manner and at a predeterminable distance (a), via spur double striplines (6, 6') to essentially planar main lines (5, 5'). All of the double striplines (5, 5'; 6, 6') have a layered structure and are mutually insulated by a thin insulating layer (7), with the result that a minimum current area is achieved. The controllable semiconductor components (V1-V6) are accommodated closely adjacent to freewheeling diodes in a module (10), the heat of which can be dissipated by cooling elements (8). Bipolar transistors having an insulated gate (IGBTs) are preferably used as controllable semiconductor components (V1-V6).Type: GrantFiled: March 14, 1996Date of Patent: November 10, 1998Assignee: Asea Brown Boveri AGInventors: Markus Keller, Jochen Rees, Alexander Stoev

Patent number: 5768114Abstract: A converter circuit arrangement is disclosed. As a result of the fact that GTOs are hard driven, reverse-parallel connected diodes have a reverse current response dV/dt of 2 kV/.mu.s to 10 kV/.mu.s and a low-inductance freewheeling circuit is provided between the DC voltage source and the GTOs, the GTOs and the reverse-parallel connected diodes can be operated without a protective circuit.Type: GrantFiled: November 1, 1996Date of Patent: June 16, 1998Assignee: Asea Brown Boveri AgInventors: Horst Gruning, Jochen Rees
