METHOD OF WIRELESS ELECTRIC POWER TRANSMISSION AND DEVICE TO THIS END (VERSIONS) Russian patent published in 2011 - IPC B60L9/08 

FIELD: transport.

SUBSTANCE: invention relates to wireless transmission of electric power and can be used to supply electric transport facilities. Proposed method comprises feeding electric power from resonance power supply system via HV HF converter, one-wire line and air gap to individual current collectors. Power feed to using equipment is performed by electromagnetic induction at 0.1-1000 kHz and line voltage of 0.1-1000 kV via air gap between two helical aerials. Proposed device comprises resonance system of electric power transmission via HF HV converter, one-wire line and individual using equipment current collectors, and air transformer made up of two isolated helical aerials with air gap. Transmitting helical aerial is connected to isolated one-wire line with frequency of 0.1 -1000 kHz and voltage of 0.1-1000 kV, while receiving helical aerial is built in electric transport facility current collector and connected via step-down HF transformer, resonance circuit, rectifier and controlled inverter with electric load.

EFFECT: long-distance wireless electric power transmission.
