DEVICE OF NON-CONTACT POWER SUPPLY Russian patent published in 2013 - IPC H02J17/00 

FIELD: electrical engineering.

SUBSTANCE: device of non-contact power supply consists of the secondary winding to which power is supplied from the primary winding of AC supply source. Overall resistance (Z) Z₁ in relation to frequency has local maximum (Z_max) in proximity of frequency (f₀) of fundamental harmonic component of the above source (6) of alternate current and overall resistance (Z) Z₂ in relation to frequency has the above frequency (f₀) of fundamental harmonic component which is between frequency (f_MAx) having its local maximum (Z_MAx) in proximity of frequency (f₀) of fundamental harmonic component and frequency (f_min)> which has its local minimum (Z_min) closest to the above frequency (f₀) of fundamental harmonic component. Z₁ indicates that coefficient (k) of coupling between the primary and secondary winding is the preset value (0,3) and it is an overall resistance of the input side (Z₁) only when viewed from output side of the AC power source and Z₂ indicates that coefficient (k) of coupling between the primary and secondary winding is the preset value (0,3) and that it is overall resistance only of output end (Z₂) as viewed from load side which should be connected to the secondary winding.

EFFECT: increase of power transmission efficiency.
