Abstract

The invention relates to an arrangement comprising a first electrical component, which has a pair of flat, spaced-apart first connection lugs, a second electrical component, which has a pair of flat, spaced-apart second connection lugs, wherein the first and second connection lugs are in each case connected in pairs in an electrically conductive manner, and an electrically conductive plate which is electrically insulated from the first and second connection lugs and which is arranged below the first and second connection lugs in the plane of the surfaces of the first and second connection lugs.

Claims

1. An arrangement (10), comprising:

a first electrical component (1) having a first main body and a pair of flat, first connection lugs (3a, 3b) that each extend from a side of the main body along a first direction and are spaced apart from one another along a second, lateral direction that is perpendicular to the first direction;

a second electrical component (2) having a second main body and a pair of flat, second connection lugs (4a, 4b) that each extend from a side of the second main body along a direction opposite to the first direction and are spaced apart from one another along the second, lateral direction, wherein one of the first connection lugs overlaps with one of the second connection lugs along a third direction that is perpendicular to both the first and second directions, and wherein the other first connection lug overlaps with the other second connection lug along the third direction;

an electrically conductive plate (6) which is electrically insulated from the first and second connection lugs (3a, 3b;

4a, 4b) and which is arranged below the first and second connection lugs (3a, 3b;

4a, 4b); and

a multiplicity of electrically conductive elevated portions (8) which are disposed in a region below at least one of the first and second connection lugs (3a, 3b;

4a, 4b) and extend upwardly from the electrically conductive plate (6), wherein an air gap is disposed between the first and second connection lugs (3a, 3b;

4a, 4b) and the conductive elevated portions (8);

wherein the electrically conductive plate (6) is a planar cooling plate, wherein the cooling plate protrudes underneath the first and second lugs (4a, 4b), and is configured to dissipate waste heat from the first electrical component (1), said waste heat developing during operation of the first electrical component (1);

wherein the first electrical component (1), the second electrical component (2), and the first and second connection lugs (3a, 3b, 4a, 4b) together form an open region (A) therebetween such that currents in the first and second connection lugs (3a, 3b, 4a, 4b) are configured to produce magnetic fields that penetrate the region (A), wherein eddy currents are configured to generate in the electrically conductive plate (6), wherein the eddy currents are configured to generate magnetic fields that penetrate the region (A) in a direction opposite to the magnetic fields generated by the currents in the first and second connection lugs (3a, 3b, 4a, 4b), and wherein the elevated portions (8) are not directly located under the open region (A) along the third direction.

2. The arrangement (10) according to claim 1, further comprising:

an insulation layer (7) which is arranged between the first and second connection lugs (3a, 3b;

4a, 4b) and the electrically conductive plate (6).

3. The arrangement (10) according to claim 2, wherein the insulation layer (7) constitutes a dielectric film which has a high dielectric constant and forms a low-inductance, capacitive path between the second connection lugs (4a, 4b).

4. The arrangement (10) according to claim 1, wherein the elevated portions (8) each have a dome shape.

5. The arrangement (10) according to claim 1, wherein the first electrical component (1) is a film capacitor and the second electrical component (2) is an electrical bus bar.

6. The arrangement (10) according to claim 1, wherein the cooling plate is mounted on a lateral surface of the main body of the first electrical component (1).

7. An arrangement (10), comprising:

a first electrical component (1) having a first main body and a pair of flat, first connection lugs (3a, 3b) that each extend from a side of the main body along a first direction and are spaced apart from one another along a second, lateral direction that is perpendicular to the first direction;

a second electrical component (2) having a second main body and a pair of flat, second connection lugs (4a, 4b) that each extend from a side of the second main body along a direction opposite to the first direction and are spaced apart from one another along the second, lateral direction, wherein one of the first connection lugs overlaps with one of the second connection lugs along a third direction that is perpendicular to both the first and second directions, and wherein the other first connection lug overlaps with the other second connection lug along the third direction;

an electrically conductive plate (6) which is electrically insulated from the first and second connection lugs (3a, 3b;

4a, 4b) and which is arranged below the first and second connection lugs (3a, 3b;

4a, 4b); and

a multiplicity of electrically conductive elevated portions (8) which are disposed in a region below at least one of the first and second connection lugs (3a, 3b;

4a, 4b) and extend upwardly from the electrically conductive plate (6), wherein an air gap is disposed between the first and second connection lugs (3a, 3b;

4a, 4b) and the conductive elevated portions (8);

wherein the first electrical component (1), the second electrical component (2),

and the first and second connection lugs (3a, 3b, 4a, 4b) together form an open region (A) therebetween, wherein the elevated portions (8) are not directly located under the open region (A) along the third direction.
