VOLTAGE STABILIZER Russian patent published in 1996 - IPC

FIELD: electrical and radio engineering. SUBSTANCE: voltage stabilizer incorporates resistive voltage divider which first extreme and center leads-out connected correspondingly to output and inverting input of operational amplifier which noninverting input is linked via limiting resistor to second extreme lead-out of resistive voltage divider and via stabilizer diode - to first lead-out of regulation resistor. First and second extreme leads-out of resistive voltage divider are connected correspondingly to output and input terminal and center lead-out - to second lead-out of adjusting resistor which first lead-out is connected to zero potential wire. Ratio of value of resistance of limiting resistor to value of differential resistance of stabilizer diode is equal to ratio of value of resistance of resistor of voltage divider connected to its second lead-out to value of equivalent resistance of adjusting resistor and voltage divider resistor connected to its first lead-out connected in parallel. EFFECT: enhanced operational stability. 2 cl, 3 dwg
