COMPENSATING VOLTAGE STABILIZER Russian patent published in 1998 - IPC

FIELD: electrical engineering, in particular, secondary power supplies for electronic equipment. SUBSTANCE: device has first transistor which collector is connected to power supply line and which emitter is connected to output terminal. In addition device has first resistor, which first terminal is connected to output terminal, second and third resistors which first terminals are connected to common line, second and third transistors which emitters are connected to second terminal of third resistor. Base of third transistor is connected to connection point of second terminals of first and second resistors. In addition device has fourth and fifth transistors which emitters are connected to power supply line and which joined bases are connected to connection point of collectors of second and fourth transistors. In addition device has reference voltage source which is inserted between base of second transistor and common line. First terminal of fourth resistor is connected to power supply line. Emitters of sixth and seventh transistors are connected to common line. Their bases are connected to connection point of seventh transistor to second terminal of fourth resistor. Collector of sixth transistor is connected to connection point of base of first transistor and collectors of third and fifth transistors. EFFECT: increased stabilization rate. 2 dwg
