- AC grids are known at a constant grid frequency.
- variable frequency AC grids and, thirdly, DC grids are known.
- the first approach of the constant frequency AC mains described above has the particular advantage over variable frequency ones in that all those loads which are to be operated at the same voltage and speed during the flight of the aircraft can be connected directly to the power distribution network ,
- These consumers are for example fuel pumps, hydraulic pumps or fans.
- IDG integrated drive generators
- VFGs variable speed generators
- the DC voltage network is an alternative to the AC voltage networks.
- DC motors or DC generators with commutators should not be used in commercial aircraft, since these are very maintenance-prone and thus cost-intensive due to the required carbon brushes, brushless DC technology is used ,
- the generator or motor is operated with alternating voltage, which is generated by special motor control devices from a DC voltage network, for example, 270 V.
- the document US 4,357,524 shows an electric heating control device for heating control of an aircraft window. Furthermore, the document DE 198 21 952 C2 describes a power supply unit on board an aircraft.

Furthermore, it is possible according to the invention to couple a fuel cell as an additional energy source to the power distribution device according to the invention.
- Another advantage of the present invention is that, for the power distribution apparatus according to the invention, only a single type of network, namely a constant frequency mains alternating current network, is used for the power distribution and thus no transformations between power grids are required. This advantageously means significantly reduced energy losses in the power distribution network according to the invention or in the power distribution device according to the invention.
- the architecture of the power distribution device according to the invention results in greatly reduced power in relation to the total power provided, which would have to be conducted via converters. As a result, they can also be designed correspondingly smaller, which allows a further reduction in energy losses.
