PARAMETRIC TRANSFORMER Russian patent published in 2018 - IPC H01F27/38 G05F3/06 

FIELD: electrical equipment.

SUBSTANCE: invention relates to the electrical equipment and can be used in the design of parametric high-frequency transformers for the secondary power supply sources. Parametric transformer contains magnetic core, primary winding, output winding, connected to the capacitor resonant winding. Magnetic core has the U-shaped structure. On the magnetic core left side the C-shaped core is placed, on which the primary winding is located. On the magnetic core right part side surface, from the outer and inner sides, two identical permanent magnets are arranged, connected by the steel U-shape cage so, that the permanent magnets flux was closed along the circuit: left permanent magnet, magnetic core, right permanent magnet, steel cage, left permanent magnet, the output winding is wound on the magnetic core right end so, that its plane is perpendicular to the plane of the permanent magnets flux.

EFFECT: technical result consists in increase in the overload capacity without the oscillations attenuation due to the absence of direct electromagnetic coupling between the input, resonance and load circuit fluxes.
