CONSTANT VOLTAGE STABILISER Russian patent published in 2009 - IPC G05F1/56 

FIELD: electricity.

SUBSTANCE: invention is attributed to electric engineering and can be used in various power supply devices for radio equipment. In constant voltage stabiliser containing control transistor (4), whose emitter is connected with input lead (3), and collector is connected with output lead (2), transistor (10) of direct current amplifier with opposite conductivity type connected by collector with base of control transistor (4), by base - with output of output voltage divider, by emitter via stabilitron (9) - with common output (1), and diode (11) and starting RC-circuit formed by series-connected the first resistor (5) and condenser (12), which circuit is connected in parallel with control transistor (4), connection point of condenser (12) and the first resistor (5) of starting RC-circuit is connected with anode of diode (11), the cathode of which is connected with common output.

EFFECT: functionality enhancement while keeping automatic start of stabiliser if input voltage drops out for short intervals.
