BIPOLAR DC VOLTAGE REGULATOR Russian patent published in 2024 - IPC G05F1/585 H02M3/335 

FIELD: electrical engineering.

SUBSTANCE: constant voltage regulators, used in secondary power supply systems to regulate and stabilize constant output voltage. The device contains a power control key (1) and a magnetic element with magnetically coupled windings. The first winding of the magnetic element (3) is connected by the beginning to the first pole of the input constant voltage source, and by the end through the regulating switch (1) to the second pole of the input constant voltage source, forming a common bus. The first capacitor (2) is connected to the common connection point of the switch (1) and the winding (3), to which the first shunt diode (4) is connected by the anode, which is connected by the cathode to the first output capacitor (6), the second pole connected to the common bus and generating with parallel connected load (7) positive output voltage channel. The second winding of the magnetic element (5) is connected by the end to the common connection point of the diode anode (4) and the first capacitor (2), and by the beginning to the common bus. A second circuit with magnetically coupled antiphase windings (9, 11), each of which is antiphase to the first two windings (3, 5), is introduced into the magnetic element. The first winding (9) is connected by its end to the positive pole of the input constant voltage source, and by the beginning to the second capacitor (8), to which the cathode is connected to the second shunt diode (10), with the anode connected to the second output capacitor (12), the second pole connected to the common bus and a generator with a parallel-connected load (13) channel of negative output voltage. The second winding (11) of the newly introduced circuit is connected by the beginning to the common connection point of the second capacitor (8) with the second shunt diode (10), and by the end to the common bus.

EFFECT: formation of a bipolar output voltage.
