WELDING POWER SOURCE AND METHOD OF FORMING TIME DIVERSED SIGNALS FOR TURNING ON THYRISTOR RECTIFIERS IN WELDING POWER SOURCE

摘要

FIELD: mechanical engineering; welding. SUBSTANCE: arc welding power source driven by internal combustion engine has multiphase AC power generator, semiconductor- controlled rectifier for rectifying AC current using generator synchronizing winding for forming signals for digital synchronization converter which suppresses interference in most portion of generator pulse length. EFFECT: prevention of formation of false synchronization signals.
