First off - Hello All.
I'm a relativley new member that's been reading the forum but never posted.
I'm not an electronic engineer, I just hobby dabble a bit as I need to.
So - I've been trying to find info on using FETs instead of diodes in a full-wave bridge for a welder. I want to turn my old AC welder into a capable DC unit and a power source for a TIG add-on.
Why FETs? Because big (>100A) diodes get very expensive and I suspected that I could get plenty of MOSFETs to parallel-up for current at a better price (surplus) than suitable diodes.
Be gentle.
