SYSTEMS AND METHODS TO PROVIDE WELDING-TYPE ARC STARTING AND STABILIZATION

摘要

An example arc starting/stabilizing circuit includes: a pulse generator configured to generate voltage pulses having a first voltage; and a plurality of transformers configured to receive the voltage pulses and output the voltage pulses to a welding-type output circuit at a second voltage higher than the first voltage, wherein: each of the plurality of transformers comprises one primary winding turn, one secondary winding turn, and a core configured to magnetically couple the primary winding turn and the secondary winding turn; the primary winding turns of the plurality of transformers are coupled to the pulse generator to receive the voltage pulses; and the secondary winding turns of the plurality of transformers are coupled in series and are configured to conduct welding-type current in the welding-type output circuit.
