KEY VOLTAGE REGULATOR WITH STEPPING-UP OF OUTPUT VOLTAGE Russian patent published in 1994 - IPC

FIELD: power supply for radio equipment and for means of communication. SUBSTANCE: regulator has input filter 1, storage choke 2, switching diode 9, control element 3, multivibrator 16 controlled by differential amplifier, switching stages 4 and 7, key stages 17 and 20, voltage multiplier 11, inventor 8, auxiliary power supply source 12, delay unit 13, filtering and time setting RC-elements 19 and 5 to ensure reliable operation of equipment in case of poor quality of primary power supply. Additionally voltage regulator is provided with unit of transducers for sensing conditions of multivibrator, first and second stimulators 18 and 21. Inputs of transducers unit are collector-coupled with multivibrator 16 and output terminals of this unit are connected with input terminals of stimulators, output terminals of which are connected with multivibrator control output terminals. EFFECT: enlarged field of application due to capability to ensure reliable operation at poor quality of primary power supply. 2 dwg
