ELECTRIC ENERGY RECEPTION DEVICE AND ELECTRIC ENERGY TRANSMISSION DEVICE Russian patent published in 2018 - IPC H01F27/36 B60L11/18 H02J50/12 

FIELD: electrical engineering.

SUBSTANCE: using in electrical engineering. According to the invention, an electric power receiving device includes a ferrite, as well as a coil for receiving the electrical energy, where a hollow portion is formed. Coil of the electric energy reception is made so to surround the winding axis that runs in the thickness direction. If one looks at the coil of the electric energy reception and the ferrite from the observation position spatially remote from the coil of the electric energy reception in the direction, in which the winding axis runs, the grooved portions are formed on the outer peripheral portion of the ferrite so that the grooved portions are overlapped with the side portions of the coil. Width of each grooved portion if measured in the circumferential direction of the coil of the electric energy reception is increased when removing from the hollow portion of the electrical energy reception coil.

EFFECT: technical result is an increase in the coefficient of communication of the wireless power transmission with a decrease in the material consumption.
