MAGNETICALLY COUPLED CONSTANT VOLTAGE REGULATOR OF STEP-UP TYPE Russian patent published in 2025 - IPC H02M3/335 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering, in particular to constant voltage regulators, and can be used in secondary power supply systems for regulation and stabilization of constant output voltage. Device contains control key 1, linear inductance 2, containing three windings 3, 4, 5 with equal number of turns, first winding 3 of which is connected by the beginning to the positive terminal of the input constant voltage source, by the end to the positive pole of control key 1, the negative pole of which is connected to the negative terminal of the input constant voltage source, which forms a common bus, second winding 4 is connected to the first output of the newly introduced first capacitor 6, the second output of which is connected to the common connection point of the control key with the end of first winding 3 and to the anode of shunting diode 7, the cathode of which is connected to the beginning of second winding 4, which common point of connection is connected to second capacitor 8, the second output of which is connected to the common bus, and the end of second winding 4 is connected to the first terminal of third capacitor 9, the second terminal of which is connected to the cathode of rectifying diode 10, the anode of which is connected to the beginning of second winding 4, common point of connection of the cathode of rectifier diode 10 with third capacitor 9 is connected to the end of third winding 5, the beginning of which is connected to the first output of the capacitor of filter 11 with parallel connected load 12, the second output of which is connected to the common bus.

EFFECT: formation of high output voltage – more than voltage on the control key, rectangular current pulse through the control key, reduced number of turns of the magnetic element and pulsations of output voltage, increased efficiency.
