These devices also include embedded electronics. These are systemic elements configured to perform certain operations in flight and to control the aircraft. In particular, it may be photo sensors, video cameras, control and control units provided in particular with microprocessors or microcontrollers and memories, geolocation devices, actuators for controlling the apparatus; but also systemic elements for controlling and controlling the rotating electrical machine, for example voltage sensors, current sensors, voltage converters, etc.
The rotating electrical machine and all embedded electronics require to operate to be electrically powered during the flight.
Teleoperated devices may include one or more electrical energy storage units such as batteries. These so-called active devices may have a relatively large range but have a limited autonomy and the batteries need to be recharged.
There are also so-called captive teleoperated devices that are electrically powered during the flight phase by a power source connected to the device via a cable providing both electrical and mechanical functions.
OBJECT OF THE INVENTION The invention aims to provide a power supply system for a teleoperated captive device, which is particularly powerful. The subject of the invention is thus a power supply system for a teleoperated captive device, comprising a power supply source configured to supply electrical energy, and an electrical cable electrically connected to said power supply source and configured to conveying said electrical energy to said captive teleoperated apparatus for powering at least one rotating electrical machine and / or systemic elements embedded in said teleoperated captive apparatus; characterized in that said power supply source is configured to provide a three-phase AC high voltage, said power cable is configured to route said three-phase AC high voltage, and said system further comprises an onboard energy management and conversion device in said teleoperated apparatus captive and configured to rectify said three-phase AC high voltage received in a high DC voltage and to lower said DC high voltage to DC low voltage.
In the electrical power supply system according to the invention, the provision and routing to the remote teleoperated apparatus of a three-phase AC high voltage makes it possible to satisfy the needs, in particular instantaneous power, of this apparatus. Note that the device can for example require a power of the order of 2 kW to 5 kW.
The provision by the power source of a three-phase AC high voltage makes it possible, for a given power, to reduce the intensity supplied.

Thanks to the power supply system according to the invention, the supply and routing to the teleoperated device captive high-voltage AC three-phase does not impact the compactness and weight of this device.
The power source may be configured to provide electrical power having a three-phase high-ac voltage having a value between about 350 V and about 700 V and an intensity value of less than 10 A; said power management and conversion device may be configured to rectify the received AC electrical energy into a DC electrical power having a DC high voltage having a value between about +/- 300 V and about +/- 600 V and an intensity value also less than 10 A, and then to regulate the rectified continuous electrical energy into an electrical energy having a low DC voltage having a value between about 30 V and about 70 V and an intensity value between about 30 A and about 60 A or at most 80 A.
It will be noted that the positive and negative values of the rectified DC high voltage correspond to the two branches, also called rails, of a three-phase rectifier.

FIG. 1 further shows a holding system 8 introduced into the internal space 7 of the chassis 3, designed to maintain in parked position a teleoperated rotary wing apparatus 13.
The holding system 8 comprises a mobile receiving platform 9 intended to receive the apparatus 10, a side wall 10 here cylindrical, delimiting at the periphery a reception space 12 for the apparatus 10, as well as a locking device 11 mounted on the side wall 13 and which is configured to block the rotary wing 13 of the apparatus 10 when the latter is in the stationary position on the platform 9 and in the reception area 12.
FIG. 1 furthermore shows a plurality of electrical and / or mechanical boxes 14 mounted on the frame 3 and which each comprise electronic and / or electrotechnical and / or mechanical system elements to enable the apparatus 10 to carry out phases of flight during which he must perform missions (or tasks).
As can be seen schematically in FIG. 2, the apparatus 10 is here a drone, that is to say an aerial teleoperated apparatus with a rotary wing.
This apparatus 10 comprises a main body 15 provided with a rotating electrical machine 16 (visible in FIG. 5) used in motor mode and on-board electronics formed by systemic elements, for example control and control units provided in particular with microprocessors or microcontrollers and memories, geolocation devices, actuators for controlling the apparatus, but also systemic elements for controlling and controlling the rotating electrical machine, for example voltage sensors, current sensors, power converters, voltage, etc. (see below in more detail). The apparatus 10 further comprises two sets of several blades 13 (here three) disposed on either side of the main body 15, a so-called upper set and a lower set, each blade 13 of a set of blades being connected. mechanically to a rotor of the rotating electrical machine 16. The two sets of blades 13 here form the rotary wing of the apparatus 10.
Note that the rotating electrical machine 16 is for example a brushless motor said in English terminology "brushiess". The apparatus 10 also comprises several feet 17 (here three) extending from the main body 15, under the lower set of blades 1, opposite the feet 17, a cover 18 situated above the main body 15 and the blade set 13 said upper, which cover 18 is also provided with embedded electronics and in particular communication systems, including for example an antenna (not shown) protruding from the cover; and other systemic elements, for example video and / or photo sensors 19 housed under the main body 15 and the lower set of blades 13, between the legs 17.
The rotating electrical machine 13 and all the embedded electronics require, in order to function, to be electrically powered during the flight phases. The apparatus 10 is here electrically and mechanically connected by an electric cable 20 to a power supply 21 (visible in FIG. 4) mounted on the chassis 3.
The power source 21 is configured to provide electrical power and the cable 20 is electrically connected to the power source 21 and is configured to route electrical power to the apparatus 10 to power at least the rotating electrical machine 16, or even all the systemic elements embedded in the apparatus 10.
In particular, the power source 21 is configured to provide a three-phase AC high voltage and the electrical cable 20 is configured to route this high-voltage three-phase AC to the apparatus 10.
Such an apparatus 10 is said to be captive since its radius of action is limited by the length of the cable 20.
Here, the cable 20 has a length greater than 50 m and less than about 200 m, and preferably about 150 m.
FIG. 3 shows, in section, the detail of the cable 20, which comprises three main conductors 22 each insulated by a sheath 23 and each formed here of a plurality of strands 24.
Each main conductor 22 is dedicated to one of the three phases to the three-phase voltage (or current) system generated by the power supply 21.
The strands 24 are for example tinned copper and has a substantially hexagonal shape whose section (area) is here equal to 0.38 mm ^.
The sheath 23 is for example made of thermoplastic elastomer, in particular polyester.
The cable 20 further comprises a neutral conductor 25 insulated by a sheath 26, for example similar to the sheath 23, and each formed of a plurality of strands 27, for example also similar to the strands 24.
The cable 20 here comprises an optical fiber 28 configured to pass data via cable 20 to and from the apparatus 10.

The braid 30 is for example formed of viscose coated with acrylic and has a diameter of about 3.6 mm.
The cable 20 illustrated in Figure 3 here has a linear density of between about 20 g / m and about 30 g / m.
It will be noted that the assembly formed at least of the cable 20 of the power supply source 16 forms a power supply system 21 of the apparatus 10.
In this power supply system, supply and routing to the apparatus 10 of a three-phase AC high voltage makes it possible to satisfy the needs, in particular instantaneous power, of this apparatus 10. It will be noted that the apparatus 10 may for example require a power of the order of 2 kW to 5 kW.
The supply by the power source 21 of a three-phase AC high voltage makes it possible, for a given power, to reduce the intensity supplied and thus transited in the cable 20.
The cable 20 thus travels electrical energy having a three-phase AC high voltage and a low intensity, which makes it possible to use a cable of small diameter and therefore having a reduced linear density and reduced Joule losses.
It will be noted that for a given weight, the reduction of the linear density of the cable 20 advantageously makes it possible to increase the length thereof. The power supply system therefore allows the device to have a particularly large radius of action for a teleoperated captive device.
