As a result, interference fields that can be traced back to the high input current levels and the quick switching of the power module(s), and which spread out substantially parallel to the flat power module(s), are input less into the interconnect devices. This improves the functionality of the control apparatus. Furthermore, there is no need for additional filtering in order to compensate for the interference. This reduces the production costs for the control apparatus.

According to one embodiment, the first section and the second section are at a right angle to one another.

As a result, the control apparatus can be cube-shaped, such that it has a well-defined structure that facilitates its integration in the installation space in a vehicle.

According to another embodiment, the numerous power modules are attached to two opposing sides of the cooler.

This increases the number of power modules that are cooled, without requiring more installation space. The power density of the control apparatus is therefore comparatively greater.

According to another embodiment, the cooler is located on a main surface of the power module, or at least one of the numerous power modules, defined by the main planes.

As a result, the cooler requires very little space, thus allowing for a compact control apparatus.

According to another embodiment, the intermediate circuit capacitor is located in an installation space defined by power module(s) and the interconnect device.

The installation space preferably extends from a main surface of the power module(s) along a first wall formed by the first section, and a second wall formed by the second section. The main surface also preferably faces away from the cooler.
