WIDE-RANGE CONSTANT VOLTAGE REGULATOR Russian patent published in 2024 - IPC H02M3/10 G05F1/46 

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 control and stabilization of constant output voltage. Device comprises power control switch (1), two linear inductors (2, 3) connected in series through capacitor (4). First inductor (2) by the first pole is connected to the positive output of the input DC voltage source, and by the other pole through control switch (1) to the negative output of the input DC voltage source, which forms a common bus. Second linear inductor (3) is connected by the first pole to capacitor (4), and by the second pole — to output voltage generating capacitor (5) with load (6) connected in parallel, which second pole is connected to common bus. Device includes second power control switch (7), connected by one pole to positive terminal of input constant voltage source, and the second pole is connected to the common point of connection of capacitor (4) and second linear inductor (3).

EFFECT: formation of wide range of output voltage variation from positive to negative value.
