DIRECT CURRENT WELDING POWER SOURCE

摘要

A welding power source comprising a rectifier connected on the output side of a welding transformer receiving a single phase AC input, a reactor having a closed magnetic flux path structure circuit and connected to the output side of the rectifier, said reactor having two windings which are wound so that the flux produced by one winding cancels the flux produced by the other winding; the junction between the two windings being connected to the rectifier, and a charging and discharging capacitor connected to one of the two windings, the output of the power source being taken from the other winding.
