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 comprises power control key (1), two linear inductors (2, 7) connected in series through capacitor (6), first linear inductor (9) contains two windings (3, 4), primary winding (3) of which is connected to the positive terminal of the input constant voltage source, and by the end through control key (1) to the negative terminal of the input constant voltage source, which forms a common bus, and through capacitor (6) to second linear inductance (7), which by the second pole is connected to common point of connection, which forms output voltage of output capacitor (8) with parallel connected load (9), the second pole of which is connected to common bus. Device includes shunt diode (5), by anode connected to end of secondary winding (4) of first linear inductor (2), the beginning of which is connected to the common point of connection of the end of primary winding (3) and control key (1), and by the cathode to the common point of connection of capacitor (6) with second linear inductor (7).
EFFECT: reduced pulse current through control key, higher efficiency.
