DC VOLTAGE STABILIZER Russian patent published in 1994 - IPC

FIELD: secondary power supply source. SUBSTANCE: device has a regulating element composed of power 6, matching 5 and control 4 transistors, control unit 8 the output of which is connected to the base of transistor 4, semiconductor element 9 and limiting element 10 connected in series between output terminal 3 and common bus. The limiting element is composed of serially-connected inverter 11, transformer 12 and rectifying-filtering unit 13 to reduce power consumption and enhanced efficiency. EFFECT: enhanced efficiency and reduced power consumption. 1 dwg
