REGULATED DC VOLTAGE CONVERTER WITH PROTECTIVE GEAR Russian patent published in 1999 - IPC

FIELD: electrical engineering; secondary power supplies. SUBSTANCE: converter has power rectifier with filter, adjustable single-ended and double-output converter, two forward-connected rectifier diodes, output filter, voltage corrector, control and protective gear, two RS flip-flops, two AND gates, power amplifier, voltage sensor, stepless starting unit, reference-current generator, control signal adding unit, DC generator, two integrators, two isolating diodes, reset circuit, hysteresis-loop threshold element, second threshold element, one-shot multivibrator, and two NOT buffer gates. Novelty is introduction of relaxation generator and adding third and fourth NOT buffer gates, third double-input AND gate, and double-input OR gate to control and protective gear. EFFECT: improved reliability at converter output under steady state conditions upon connection to supply mains. 4 dwg
