Abstract

A component assembly for power electronics, having at least one power module, at least one separate connection module, a separate control circuit carrier, and a housing. The at least one power module, the at least one connection module, and the separate control circuit carrier are arranged in a specified manner in the housing. The at least one power module is connected via first electrical signal lines to the at least one connection module and the at least one connection module is connected to the control circuit carrier via second electrical signal lines.

First claim

What is claimed is:

1 . A component assembly for power electronics, the component assembly comprising:
at least one power module; at least one separate connection module; a separate control circuit carrier; and a housing, wherein the at least one power module, the at least one connection module, and the separate control circuit carrier are arranged in a specified manner in the housing, wherein the at least one power module is connected via first electrical signal lines to the at least one connection module, wherein the at least one connection module is connected to the control circuit carrier via second electrical signal lines, and wherein the at least one connection module has a predetermined electrical line layout that electrically connects connection areas of the first electrical signal lines in a predetermined manner with connection areas of the second electrical signal lines.

2 . The component assembly according to claim 1 , wherein at least a number of the connection areas at which the first and second electrical signal lines are each connected to the at least one power module, the at least one connection module and/or the control circuit carrier are at least partially surrounded by a molding compound, respectively.

3 . The component assembly according to claim 1 , wherein the at least one power module, the at least one connection module and the control circuit carrier are each arranged in a different plane.

4 . The component assembly according to claim 1 , wherein the at least one power module, the at least one connection module and the control circuit carrier are mechanically connected to the housing.

5 . The component assembly according to claim 1 , wherein the at least one power module is at least partially disposed between the control circuit carrier and the housing, wherein the at least one connection module, with respect to a direction of expansion of a plane of the control circuit carrier, is disposed next to the control circuit carrier.

6 . The component assembly according to claim 1 , wherein at least a number of the first electrical signal lines and/or the second electrical signal lines are formed as bond connections.

7 . The component assembly according to claim 1 , wherein at least a number of the first electrical signal lines and/or the second electrical signal lines are formed as electrically conductive sheets.

8 . A vehicle comprising at least one of the component assembly according to claim 1 .

9 . A method for providing a component assembly for power electronics, the method comprising:
arranging at least one power module, at least one separate connection module, and a separate control circuit carrier in a predetermined manner and sequence in a housing; and electrically connecting the at least one power module, the at least one separate connection module, and the separate control circuit carrier, wherein the at least one power module is connected to the at least one connection module via a first electrical signal line and the at least one connection module is connected to the control circuit carrier via a second electrical signal line, and wherein the at least one connection module has a predetermined electrical line layout that electrically connects connection areas of the first electrical signal lines in a predetermined manner with connection areas of the second electrical signal lines.
