VOLTAGE STABILIZER Russian patent published in 2003 - IPC

FIELD: electrical engineering, possibly secondary power source for supplying electric energy to radioelectronic equipment. SUBSTANCE: stabilizer includes first, second and third transistors 1, 4, 5 respectively; first and second resistors 2, 3; reference voltage source 6; electric current stabilizing two-terminal network 7; first and second electric current followers 8, 9. At positive increment of output voltage (at decrease of current H) electric current passing trough transistor 5 forming differentiating cascade together with transistor 4 and electric current passing to base of transistor 1 decreases. Voltage increment at output of transistor 1 is compensated; current at output of transistor 9 increases for increasing current passing through emitter of transistor 4. At any value of electric current H difference of electric currents of transistors 4 and 5 forming circuit for comparing part of output voltage with reference voltage has constant value. Output voltage of stabilizer does not depend upon electric current value H. EFFECT: enhanced stability of output voltage at change of load current. 2 dwg
