DC VOLTAGE-TO-DC VOLTAGE CONVERTER Russian patent published in 1997 - IPC

Abstract RU 2080221 C1

FIELD: electrical engineering; supply sources for DC arc welding. SUBSTANCE: DC voltage-to-dc voltage converter has main and reverse-conducting thyristors, resonant circuit capacitors, resonant circuit reactors, transformer, rectifier and capacitive ripple filter. Reverse-conducting thyristors are placed in parallel opposition with main thyristors and resonant circuit reactor windings connected in series with main thyristors. EFFECT: improved reliability of welding supply source. 2 dwg
