Supplementary power supply for vehicles, in particular aircraft

A supplementary power supply comprising a solar generator for ohmic consumers in a vehicle,

• wherein the vehicle is an aircraft, and wherein the solar generator is arranged at least on or in a part of the outer surface of the aircraft,
• wherein a control circuit is electrically connected to a multiplicity of solar cells via generator terminals of the solar generator and comprises at least one output terminal,
• wherein the at least one output terminal is connected or adapted to be selectively connected to a consumer system, and wherein the consumer system has associated to it a specific nominal voltage and a specific nominal current that corresponds to a momentary rate of utilization of the consumer system, wherein the consumer system includes at least one from the group of:
• fuel management, primary flight control, secondary flight control, braking systems, toilets and onboard kitchens, and cabin air conditioning, and wherein the specific nominal voltage includes at least one voltage from the group of:
• 28 V, 115 V, and 230 V, and
• wherein the control circuit interconnects the at least one output terminal with the multiplicity of solar cells such that a nominal voltage and a nominal current are available at the at least one output terminal, and wherein for a particular output current at a particular insolation intensity a corresponding number of solar cells is connected in parallel and for a particular output voltage a corresponding number of solar cells is connected in series.
