MAGNETICALLY COUPLED 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, first of which, through control key 1, is connected by beginning to positive terminal of input constant voltage source, by end to first capacitor 5, which second output is connected to negative output of input constant voltage source, which forms common bus, common point of connection of the beginning of first winding 3 with the control key is connected to the cathode of first shunting diode 7, which anode is connected to common bus and to first output of second capacitor 6, which second output is connected to the cathode of the second shunt diode 8, which anode is connected to the common point of connection of the end of first winding 3 with capacitor 5 and to the beginning of second winding 4, end of which is connected to first output of capacitor of filter 9, which second output is connected to common bus, load 10 is connected in parallel to capacitor of filter 9.

EFFECT: increased steepness of control characteristic, reduced pulsations of output voltage.
