Abstract:
1. An electricity power supply circuit in an aircraft, the circuit comprising: at least one first power supply generator mechanically coupled to an engine of the aircraft for delivering an alternating voltage; a distribution network connected to said at least one generator to receive said alternating voltage for distributing electricity on board the aircraft and powering electrical equipment situated in the engine of the aircraft or in the environment of said engine; a DC voltage distribution bus connected to a voltage converter circuit powered by said distribution network, the electrical equipment comprising nacelle loads connected to said DC voltage distribution bus; a second power supply generator integrated in the aircraft engine and connected to a circuit for de-icing the engine nacelle or a wing carrying the engine, the power from the second power supply generator being fed to the de-icing circuit without transiting through said distribution network; and a connection between said DC voltage distribution bus and at least one electrical resistance included in said de-icing circuit for dissipating within said resistance electricity returned to the DC voltage distribution bus by at least some of the nacelle loads.
