Abstract:
1. A device for providing an electrical system alternating voltage for an electrical system of an aircraft, comprising: at least one engine generator which provides an alternating voltage; at least one fuel cell which provides a direct voltage; at least one frequency converter for converting the alternating voltage provided by the engine generators into a first output alternating voltage; and at least one cyclo-inverter for cyclo-inverting a direct voltage provided by the at least one fuel cell into a second output alternating voltage which is synchronous with the first output alternating voltage and, together with the first output alternating voltage, constitutes the electrical system alternating voltage; wherein the at least one frequency converter is configured to reduce at least in part a power provided by the at least one frequency converter and the cyclo-inverter is configured to increase by the same amount the power provided by the cyclo-inverter to carry out a load compensation control following the frequency compensation.
