POWER SOURCE FOR WELDING AND METHOD OF GENERATING A LARGE NUMBER OF TIME SEPARATED SIGNALS FOR THAT SOURCE (VARIANTS) Russian patent published in 1997 - IPC

FIELD: electrical engineering. SUBSTANCE: power source and method of generating signals for arc welding with use of internal combustion engine as drive unit, polyphase power generator of alternating current rectified by means of controlled semiconductor rectifier include use of single synchronizing winding of generator forming signals for digital synchronization converter suppressing noise for a large part of periods of signals of said generator. Synchronizing circuit eliminates possibility of generating false synchrosignals. EFFECT: enhanced reliability of power source operation. 46 cl, 5 dwg
