Abstract
The present invention relates to a device for supplying electrical power to a wired system for a drone (1). The device according to the invention includes at least one power converter (4) on the ground and one power converter (2) at the level of the drone (1), regulation at the level of the converter on the ground ensures that the output voltage of the power converter (4) on the ground increases when the output current of the power converter (4) on the ground increases. The method according to the invention is intended for all wired drones, the wire (3) of which is used to supply electrical power to the drone (1).
Claims19
A device for supplying power to a wired drone, including at least:
- a ground based power converter,
- a power converter at a level of the drone,
- a cable connecting the power converters and,
- wherein a regulation of the ground based power converter ensures that a voltage UB delivered by the ground based power converter increases when a current IB delivered by the ground based power converter increases, and the voltage UB occurs over a power range of normal use of the drone and wherein the regulation of the ground based power converter ensures a voltage UD at an input of the power converter at the level of the drone, is close to an optimal operating voltage of the power converter at the level of the drone, wherein the power converter at the level of the drone has a fixed ratio of output voltage with respect to the voltage UD at the input of the power converter at the level of the drone.
