Embodiment Construction

[0030] figure 1 and figure 2 A perspective view of a carrier 1 is shown, in which three busbars 2 are respectively guided in first receptacles 3 . The busbars 2 are arranged next to each other such that their flat sides are each aligned in a plane. The busbar 2 runs at a right angle in the exemplary embodiment shown, wherein the busbar 2, figure 1 The laterally protruding ends shown at the lower edge of the carrier 1 are connected in the assembled state to a power semiconductor module comprising a plurality of connected power semiconductors, in particular bipolar transistors with insulated gates (IGBT). In terms of production technology, the joining is preferably carried out by means of butt welding.

[0031] The busbar 2 is held in the first receptacle 3 with a material fit. The support 1 also includes a second receptacle 4 , which is configured in the form of a slit and is arranged in the region of the first receptacle 3 . In each case a magnetic flux guide 5 is arran...

Abstract

The invention relates to a support (1) for at least one busbar (2), comprising: at least one fixing element (10) for fixing at an electronic module (9); a first Receptacle (3) and a second receptacle (4) for a lamellar flux guide (5). The magnetic flux guide ( 5 ) arranged in the second receptacle ( 4 ) at least partially surrounds the busbar ( 2 ) arranged in the first receptacle ( 3 ) at the edge. An electrically insulating section (6) is arranged between the busbar (2) and the flux guide (5). The invention also relates to a component arrangement (13) for power electronics with at least one busbar (2), a flux guide (5) and such a carrier (1), and to a The method of this bracket (1).

Description

technical field [0001] The invention relates to a carrier for at least one busbar, a component arrangement for power electronics with such a carrier and a method for producing such a carrier. Background technique [0002] Power electronics are used, for example, in electrically driven motor vehicles, and it is known in the field of such power electronics to transmit current by means of busbars. For example, in the context of regulating and / or controlling electrical components of an electrically driven vehicle, in particular in the context of controlling an electric motor used as an electric drive, the intensity of the current flowing in the busbar must be measured and Monitor as necessary. The current intensity is detected, for example, by utilizing the Hall effect by means of so-called Hall sensors. Hall sensors are often combined with flux compressors or flux guides constructed of high permeability materials and placed in close proximity to current-carrying busbars in or...
