The invention relates to an electrical fuse for rotary current generators, having a rectifier assembly ( ) for supplying a DC network, in particular in motor vehicles. To achieve simple, cost-effective and rapid-response fuse performance in the event of an overload, it is provided that a fuse element ( ) be disposed in a line strand, carrying all the generator current, between the rectifier assembly ( ) and a DC connection terminal ( ) of the generator.

Electrical fuse for rotary current generator with rectifier

A cooling body-conductor strips arrangement for electrical devices has a cooling body for withdrawing heat to a surrounding area, a base plate composed of an electrically insulating material and provided with a first conductor strip unit which is embedded in the material of the base plate, the base plate being flatly connected with the cooling body.

Cooling body-conductor strips arrangement

The invention concerns a semiconductor power element (diode ) having a lead ( ) and a safety fuse ( ) situated in the main current path that blows when overheated, particularly for use in the electrical system of motor vehicles. In order to achieve a previously determined, purposeful disconnection of the endangered element in order to avoid consequential damages when semiconductor power elements become overloaded, it is proposed that a segment ( ) of the lead ( ) and/or its points of contact in the main current path of the semiconductor be designed as a safety fuse ( ) that blows when a specified, current-dependent temperature value is reached.

Semiconductor power component comprising a safety fuse

A rectifier arrangement for a three-phase generator having at least one power diode allocated to each half-wave of each phase and a cooling arrangement for the power diodes. The power diodes may be designed as diode chips and be arranged between two diametrically opposed heat sinks, while being oriented with respect to polarity and electrically and/or thermally conductive.

Rectifier arrangement for a three-phase generator

The rectifier arrangement, preferably for a three-phase generator for a motor vehicle, has at least one power diode of positive polarity and at least one power diode of negative polarity assigned to respective half waves of each phase of the three-phase current and a cooling arrangement for the power diodes, the power diodes of like polarity being arranged on respective heat sinks in an electrically and thermally conductive fashion, and the heat sinks being sandwiched together with at least one electrically insulating part (32) which contains the electrical conductors between the diodes and the three-phase winding. The electrically conductive connections of the power diodes (12, 14) of positive and negative polarity to the phases (U, V, W) of the three-phase generator extend within the electrically insulating part (32) so that electrical contact is made with the power diodes (12, 14) of positive and negative polarities in respective cavities (40, 44) in the insulating part (32) via in each case one spring element. A punched grid (34) for each of the phases (U, V, W) extends in the cavities and includes conductor tracks (50) and spring elements (48, 49) for making electrical contact between pairs of power diodes of opposite polarity and each phase.
