ALTERNATING CURRENT VOLTAGE STABILIZER Russian patent published in 2000 - IPC

FIELD: power supply for electric equipment, communication systems, automatic and telemechanic systems, illumination networks. SUBSTANCE: stabilizer having transformer and switching unit also includes limiting resistor and connected in parallel with it closing contact of intermediate member. Capacitor is connected in parallel with primary winding of said transformer. Controlling comparator has two identical circuits for controlling and monitoring. Outputs of said circuits are connected with additional power source whose inlet is connected with phase and zero conductors. Circuit for controlling and monitoring, three-phase variant of stabilizer with use of additional intermediate units and control circuits used in one-phase variant of invention, variants of "single-side" limitation are given in description of invention. EFFECT: simplified power supply circuit of stabilizer, enhanced parameters of reliability and electromagnetic compatibility. 5 cl, 6 dwg
