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

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering and can be used as radio hardware secondary power source. Stabiliser comprises control transistor (1) with emitter connected to stabiliser input terminal and collector connected to output terminal. It comprises also DC amplifier transistor (2) with opposite type of conductance, collector-connected to the base of control transistor (1) and base-connected to the output of output voltage divider built around resistors (4 and 5). Its emitter is connected, via stabiliser diode (3), with output terminal and, 2^nd resistor, with common terminal. Proposed stabiliser comprises also starting RC-circuit consisting of capacitor(7) and 1^st resistor (6), and 1^st diode (8). In compliance with this invention, additionally, stabiliser incorporates 2^nd diode (10) with its cathode connected to the points of connected between 1^st resistor (6) and 1^st diode (8). The latter has its cathode connected to output terminal, while anode of 2^nd diode (10) is connected to common output terminal. Note here that the output terminal of capacitor (7) is connected to stabiliser input terminal.

EFFECT: starting stabiliser at intermittent fault of input voltage, simplified starting circuit.
