If the cooler is populated on both sides with power modules that have a first power module group and a second power module group, the assembly comprising the power module(s) and the cooler is preferably located in the middle of the first and/or second section of the interconnect device, such that the first or second sections of the interconnect device extend over both power module groups. In this case, there are two installation spaces, in each of which an intermediate circuit capacitor can be received.

Embodiments shall now be described merely by way of example, and in reference to the attached drawings.

FIG. 1 shows a schematic illustration of a control apparatus 10, preferably in the form of an inverter. The control apparatus 10 has an active cooler 12, a power module 16, an intermediate circuit capacitor 14, an interconnect device 18, and a connection 13. The interconnect device 18 comprises a first section 17 for activating the driver for the power module 16 (indicated by a unidirectional arrow) and a second section 19 for control (indicated by a bidirectional arrow). The positions of the various components in the control apparatus 10 shown in FIG. 1 are purely schematic, and not be understood as drawn to scale.
