SYSTEM OF CONTACTLESS TRANSMISSION OF POWER Russian patent published in 2014 - IPC H02J5/00 

FIELD: electricity.

SUBSTANCE: invention is related to the sphere of contactless power transmission. System of contactless power transmission contains basic unit (1) with several circuit for magnetic field generation and device (10) which is separable from the above basic unit (1) and has receiving inductor adapted for receipt of power inductively when the above device (10) is close to one of the above generation circuits; at that the above basic unit (1) contains controller (3) configured to define a transmission circuit (2') from above generation circuits when the above receiving inductor is located close to the above transmission circuit (2') upon which the above transmission circuit (2') is operated for generation of the first magnetic field (8) having the first phase for current induction in the above receiving inductor and at least one of remaining circuits is operated as compensating circuit (2", 52, 82) for generation of the second magnetic field (21) having phase opposite to the above first phase.

EFFECT: reducing stray magnetic field.
