PARAMETRIC TRANSFORMER Russian patent published in 2024 - IPC H01F30/06 H01F29/14 H01F27/30 G05F3/06 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering, namely to conversion equipment, and can be used in secondary power supplies, voltage converters and devices for galvanic isolation of power and signal circuits. Parametric transformer comprises a composite magnetic conductor of an armoured type, consisting of two side sections and a middle section, an input winding connected to the network, an output winding divided into two equal parts arranged on the side sections of the magnetic core and connected in series-oppositely. Magnetic conductor is divided into two parallel identical parts. Input winding is located in the through holes inside the middle sections of the parallel parts of the magnetic conductor in the axial direction, and the output winding is connected by leads to the capacitor and forms a resonant circuit with it.

EFFECT: increased parametric component of electromotive force due to increased amplitude of induction, amplitude of change of magnetic permeability and, accordingly, amplitude of change of inductance with exclusion of magnetic flux buckling in the saturation zone.
