STEP-DOWN CONSTANT VOLTAGE REGULATOR Russian patent published in 2025 - IPC H02M3/155 

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 two windings 3, 4, primary winding 3 of which is connected to the positive terminal of the input constant voltage source, by the end to the cathode of first diode 5, which anode is connected to negative output of input constant voltage source, which forms common bus, and secondary winding 4 is connected by its end to first output of control key 1, second output of which is connected to first output of capacitor 6, second output of which is connected to beginning of winding 4, common point of connection of which is connected to capacitor 7, the second output of which is connected to common bus, load 8 is connected in parallel to capacitors 6, 7, and common point of connection of end of primary winding 3 of magnetic element 2 with cathode of first diode 5 is connected to anode of second diode 9, cathode of which is connected to common point of connection of capacitors 6, 7.

EFFECT: formation of low output voltage in relation to input voltage, rectangular current pulse through control key, reduction of number of turns of magnetic element and pulsations of output voltage, increase of efficiency.
