CONSTANT VOLTAGE STABILISER

摘要

FIELD: electricity. ^ SUBSTANCE: invention is attributed to electric engineering, specifically to highly reliable electric power supply systems. Constant voltage stabiliser has power cell which contains regulating element the output of which is connected with the first terminal of impedance coil and cathode of closing diode, the second terminal of impedance coil is connected with the first terminal of condenser and modulator input the output of which is connected with control input of regulating element while the second terminal of condenser and anode of closing diode are connected to common wire and first terminals for power source and load connection. Additionally the stabiliser contains (n-1) specified cells in each one of which current sensor is connected (via switch connected with regulating element) to the second terminal for power source connection and current sensor output is connected with the first input of threshold device the second input of which is connected to modulator input while the first terminal of condenser is connected (via isolation diode) with the second terminal for load connection. ^ EFFECT: operation reliability improvement of constant voltage stabiliser with series regulating element. ^ 1 dwg
