TRANSFORMER WITH ARBITRARY COEFFICIENTS OF TRANSFORMATION Russian patent published in 2014 - IPC H01F19/04 H01F30/04 H01F30/16 H01F27/28 

FIELD: electricity.

SUBSTANCE: secondary winding is made in the form of N identical winding connections connected in parallel and placed on top of the primary winding in its central part, where the magnetic flux caused by the primary winding is maximum. The turns of each winding connection is partially placed in one of N dielectric tubes respectively. Moreover, the first few and last few turns of the primary winding turns are partially accommodated in the first and second additional dielectric tubes respectively disposed at the edges of the primary winding. Each of the N+2 dielectric tubes located in the central part of the toroidal core, and their length is approximately equal to the height of the toroidal core.

EFFECT: increasing the coupling coefficient between the primary and secondary windings of the transformer with an arbitrary and high transformation ratio.
