ANALOG VOLTAGE REGULATOR Russian patent published in 1994 - IPC

FIELD: generator installations of transportation facilities. SUBSTANCE: analog voltage regulator has measuring section 1, regulating transistor 7, power transistor 8, reference voltage source 6 built around Zener diode; in addition it is provided with frequency-dependent feedback circuit 9. Reference voltage source is connected to base of regulating transistor 7, measuring section 1, to its emitter, and feedback circuit is inserted between base and collector of power transistor 8, which makes it possible to change regulator transistors over form digital to analog mode of operation. EFFECT: improved characteristics of electrical energy supplied, reduced radio interference. 1 dwg
