TRANSFORMER WITH ARBITRARY TRANSFORMATION COEFFICIENT Russian patent published in 2016 - IPC H01F30/16 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering and can be used for matching high-frequency radio higher-power devices having high input and output resistances and included in low-resistance channels. Transformer comprises a toroidal core and two windings of a wire, the primary and the secondary ones, wound on the toroidal core. Primary winding is made in the form of K identical windings connected in parallel, each containing N1 turns. Secondary winding is made in the form of M identical communication windings connected in parallel, each containing N2 turns, where N2<N1, placed between turns of the primary winding. Inner part of the toroidal core contains a dielectric bushing in the form of a cylinder with a projecting middle part, the diameter of which is equal to inner diameter of the toroidal core and along the circumference of which there are holes with a certain pitch for wires of the primary and the secondary windings. Number of holes is equal to the number of turns N1 of the primary winding. Dielectric bushing extends along the length outside of the height of the toroidal core with windings arranged on it and has a hole for attachment in its central part.

EFFECT: technical result is expansion of operational capabilities at provision of the possibility of attachment.
