APPARATUS AND METHOD OF TRANSMITTING ELECTRICAL POWER Russian patent published in 2020 - IPC H02J50/30 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering, in particular to the electric energy transmission device and method. In the electric power transmission device, the photodetector is in form of a cylinder on the base of which on the side opposite to the input of monochromatic radiation there is a cone reflector, base diameter of which is equal to the diameter of the cylindrical photodetector, the vertex of which is located on the axis of the cylindrical photodetector on the side of the monochromatic radiation input, plane of diode n⁺-p-p⁺ (p⁺-n-n⁺) of structures and contacts are perpendicular to surface of cylindrical photodetector and are parallel to symmetry axis of conical reflector, and height of cylindrical photodetector and diameter of conical reflector base are related by ratio h = D/2(ctgα-ctg2α), where h is height of cylindrical photodetector; D is diameter of conical reflector base; 2α is angle at conical reflector vertex; α is angle between generatrix and axis of conical reflector. Technical result is achieved by the fact that in method of electric power transmission monochromatic radiation with average flow density of 1.0–10 W/cm² directed to conical reflector, conical reflector is oriented with the apex of the cone oppositely along the flow axis of monochromatic radiation, reflecting axisymmetric monochromatic radiation at angle of 80–100° to the direction of monochromatic radiation on the cylindrical photodetector, monochromatic radiation is directed parallel to the contact plane and n⁺-p-p⁺ (p⁺-n-n⁺) of diode structures of switched photoconverters of cylindrical photodetector and converting energy of monochromatic radiation into electric energy.

EFFECT: technical result consists in providing the same illumination of all photoconverters and reduction of internal resistance and switching losses in the photodetector of laser radiation.
