PARAMETRIC ORTHOGONAL-FLOW TRANSFORMER WITH POSITIVE FEEDBACK Russian patent published in 2020 - IPC H01F21/08 G05F3/06 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the electrical equipment. Transformer with independent closed magnetic conductors comprises one input 1 and one output winding 2. Input winding 1 is located on primary magnetic conductor 3, and output winding 2 - on own secondary magnetic conductor 4. Magnetic cores 3 and 4 intersect at right angle so that magnetic flux of input winding 1 affects only change of magnetic permeability of secondary magnetic conductor at section of their intersection 5, and transformer EMF from magnetic flux of input winding 1 in secondary winding 2 is not excited. Input winding 1 is connected to alternating voltage, and output winding 2 is closed to resonance capacitor 6 and forms resonant circuit with it. On primary magnetic conductor 3 there is positive feedback winding 7 with middle point 8 dividing positive feedback winding 7 into two equal semi-windings 7-1 and 7-2, connected according to. Secondary winding 2 is connected to bridge rectifier 9 on diodes 10-13, which is connected to filter capacitor 14 and load 15 through two equal semi-windings of positive feedback. Positive feedback 7 winding is connected to output winding and load as follows: top positive semi-winding positive semi-winding 7-1 is connected to upper right diode cathode 10, which anode is connected to cathode of bottom right diode 11, beginning of output winding 2 and left cover of resonant capacitor 6. End of output winding 2 is connected to right cover of resonant capacitor 6, anode of upper left diode 12 and cathode of bottom left diode 13. Cathode of the upper left diode 12 is connected to the end of the lower semi-wind of positive feedback 7-2. Anode of the lower left diode 13 is connected to the anode of the bottom right diode 11, the lower negative coating of filter capacitor 14 and the lower end of load 15. Loading upper end 15 is connected to upper positive cover plate of filter capacitor 14 and middle point of positive feedback 7.

EFFECT: technical result is preservation of parametric transformer function with introduction of positive feedback and stability of oscillations at load increase to limit, which is greater than in prototype.
