WIRELESS CHARGING SYSTEM Russian patent published in 2023 - IPC H02J50/12 H02J7/00 

FIELD: electrical engineering; systems for providing wireless power and charging.

SUBSTANCE: charging station consists of an emitter, a power source, a flat spiral coil of the emitter, a receiver consisting of an oscillatory circuit that includes a spiral flat coil, a tuning capacitor and a battery, a monitoring, protection and control module, a resonant active oscillator, and a consumer receiver electrical energy includes an uncontrolled rectifier, a soft load switching module and an adjustable voltage converter, while the windings of the flat spiral transmitting coil of the emitter of the charging station and the turns of the flat spiral receiving coil of the receiver of the consumer of electrical energy are made of soft magnetic material and have a film coating on the outer side of the rectangular wire section with respect to the centre of the coil with a material with high electrical conductivity, while in the direction of the receiver from the outer side of the transmitting spiral coil, parallel to the plane of its turns of the winding, special plates made of from a metamaterial with high anisotropy are installed.

EFFECT: increasing the efficiency of energy transfer from the charging station to the receiver of the consumer of electrical energy.
