PULSE-OPERATED DC VOLTAGE REGULATOR Russian patent published in 1994 - IPC

FIELD: secondary power supplies for radioelectronic equipment, such as long-distance communication equipment. SUBSTANCE: regulator has double-winding choke 2, power switch 6 built around push-pull inverter using gates 7, 8 and transformer 10, full-wave rectifier 12 with capacitive filter 15, two peak detectors 17,18, analog signal adder 19, and pulsed control unit 19. Secondary winding of choke 2 has center tap. Inputs of peak detectors 17,18 are connected to half-windings of choke 2 and their outputs, to inputs of adder 19 whose output is connected to input of unit 20 whose outputs are connected to control inputs of gates 7,8. Signal approaching output voltage value is built up across adder output. This signal, when applied to input of unit 20, affords regulation in response to output voltage deviation. EFFECT: improved output voltage stability, enlarged functional capabilities. 4 dwg
