Abstract

The invention relates to an electronic module for an electric drive in a vehicle, comprising an input-side electrical connection for inputting an input current generated by an energy source; an intermediate circuit with a capacitor; a semiconductor bridge circuit, connected in parallel to the intermediate circuit, wherein the bridge circuit comprises a high-side switch, and a low-side switch connected in series to the high-side switch, wherein the high-side switch is connected to the input-side electrical connection via a first current path, wherein the low-side switch is connected to the input-side electrical connection via a second current path, wherein the first current path and the second current path are the same length; and an output-side electrical connection for outputting an output current generated by the bridge circuit from the input current.

Claims (19)

1. An electronic module for an electric drive in a vehicle, comprising:

an input-side electrical connection configured to input an input current generated by an energy source;

an intermediate circuit with a capacitor;

a semiconductor bridge circuit, connected in parallel to the intermediate circuit, wherein the bridge circuit comprises a high-side switch and a low-side switch connected in series to the high-side switch, wherein the high-side switch is connected to the input-side electrical connection via a first current path, and wherein the low-side switch is connected to the input-side electrical connection via a second current path; and

an output-side electrical connection configured to output an output current generated by the bridge circuit from the input current;

wherein, at least one of:

the first current path and the second current path are the same length; or

a first current flow in the first current path is antiparallel to a second current flow in the second current path;

wherein the semiconductor bridge circuit contains at least two bridge circuit segments assigned to different current phases, and

wherein the semiconductor bridge circuit has an annular arrangement in which the at least two bridge circuit segments each form a section of the annular arrangement.

2. The electronic module according to claim 1 , wherein the high-side switch and the low-side switch form a half bridge, wherein each of the bridge circuit segments comprises one or more half bridges, wherein the numerous half bridges in the respective bridge circuit segments are connected in parallel.

3. The electronic module according to claim 1 , wherein the high-side switch and the low-side switch in the half bridge or the half bridges of each of the bridge circuit segments are arranged along the associated section of the annular arrangement.

4. The electronic module according to claim 1 , wherein the annular arrangement is at least one of circular or polygonal.

5. The electronic module according to claim 1 , wherein the annular arrangement includes the intermediate circuit within a center of the annular arrangement.

6. The electronic module according to claim 1 , wherein the high-side switch is connected to a positive contact and the low-side switch is connected to a negative contact in the intermediate circuit.

7. The electronic module according to claim 1 , wherein the output-side electrical connection is located on a side of the bridge circuit facing away from the intermediate circuit.

8. A vehicle comprising the electronic module according to claim 1 .

9. The electronic module according claim 4 , wherein the annular arrangement is square.

10. The electronic module according to claim 5 , wherein the annular arrangement is defined by includes the capacitor of the intermediate circuit within the center of the annular arrangement.
