DC VOLTAGE STABILISER Russian patent published in 2012 - IPC G05F1/56 

FIELD: electricity.

SUBSTANCE: DC voltage stabiliser is proposed, comprising a controlling element, connected with one output to an input bus, with the other one - to outputs of a closing diode and a throttle, the other output of which is connected with an output bus and a filter capacitor, the control output of the controlling element is connected to the output of a control unit, the input of which is connected with the output bus, and its second supply bus - with the common bus, at the same time a start-up unit comprises a start-up transistor, the emitter of which is connected to a point of connection of the input bus and output of the second resistor, the base - with the output of the first resistor, the other output of which is connected with the cathode of the first diode, the collector - with the output of the start-up resistor, the other output of which is connected with an anode of a decoupling diode and with the first bus of the control unit supply, the cathode of the decoupling diode is connected to the output bus, and also the second diode and the capacitor, at the same time the anode of the first diode is connected with the cathode of the second diode and via a capacitor is connected to the common bus, at the same time the anode of the second diode is connected with the collector of the start-up transistor.

EFFECT: simplified start-up circuit and higher reliability of a device.
