FIELD: electricity.SUBSTANCE: compensation stabiliser of DC voltage is proposed, comprising a controlling transistor, connected by an emitter and a collector to accordingly input and output leads, a differential amplifier on the first and second transistors, connected emitters of which via a resistor of the differential amplifier are connected to a common bus, at the same time the collector of the second transistor is connected with a base of the controlling transistor, and the collector of the first transistor - with an output lead, the base of the second transistor is connected to the point of connection of the leads of start-up and limiting resistors and a support element, the other lead of which is connected with a common bus, the other lead of the limiting resistor is connected to the output lead, and also a divider of output voltage, the output of which is connected with the base of the first transistor, at the same time a diode and a capacitor are introduced, and the capacitor is connected between the output of the start-up resistor and the base of the controlling transistor, the base-emitter transition of which is shunted with a diode in reverse direction.EFFECT: increased reliability of a device and stability of output voltage.2 dwg |
