ELECTRIC HIGH-FREQUENCY RESONANT TRANSFORMER (VERSIONS) Russian patent published in 2011 - IPC H01F19/04 

FIELD: electricity.

SUBSTANCE: magnetic conductor is a resonant winding to increase connection between the primary and secondary windings specified by good quality of a quarter-wave-length vibrator it forms. The electric high-frequency transformer is additionally equipped with a resonant winding (a resonator), arranged in the form of a helical coil with winding length equal to a quarter of current and voltage standing wave length and made of serially connected sections of helically wound insulated wire, cut of which is different for every section and reduces as the section moves away from the beginning of the resonant winding. Above the resonant winding, near its beginning in the area of current loop formation, there are the primary and secondary windings connected to a generator and a load. Resonant frequency of primary, secondary and resonant winding circuits are equal to each other. Beginnings of primary, secondary and resonant windings are electrically connected to each other and are grounded, and the second lead of the resonant winding is insulated. Beginnings of primary and secondary windings may be connected to each other, and beginning of the resonant winding is grounded, and its end is insulated. The primary and secondary windings may be galvanically isolated, and beginning of the resonant winding is grounded, and its end is insulated.

EFFECT: increased transmitted capacity and working frequency by exclusion of a magnetic conductor, provision of possibility to connect to the outlet of low-resistance loads transformer.
