A three-dimensional arrangement for a power converter device, e.g., an inverter or a rectifier, is provided. The switching elements, activation electronics, the load connections of the power converter device are arranged on a carrier device in such a way that defines especially short conduction paths. The components of the power converter device (e.g., all required components), such as switching elements, control electronics, and load connections, are arranged on a common carrier device. The carrier device is simultaneously used as a cooling device for the entire switching device. The power converter device may thereby achieve particularly efficient performance.
