I have two questions about transformers and diodes, the objective is to make a power supply for an electrolyser, which needs high amperage (probably at least 100A) low voltage DC to operate (the potential difference across the electrolyser is less than 3V with the current power supply, I have no way to find the amps until my amp meter comes in, but it's going to be pretty high)
The first question is: if a full wave rectifier (no capacitor) were attached to the primary of a transformer would the transformer operate as if it were operating on mains current, except with pulsed DC? It's much easier for me to find high voltage low amperage diodes than high amperage low voltage diodes.
Second question: If a transformer has multiple secondaries, each with the same number of winds and a full wave rectifier attached to each, could the outputs of the rectifiers be placed in parallel to make the diodes work together? I have been told that diodes will not normally work together in parallel very well as the diode with the lowest forwards voltage drop will carry all the current, and burn out if it's capacity is exceeded.
I ordered diodes for my Lincoln 225, which will have the advantage of turning it into an AC/DC Lincoln 225, but that isn't an ideal power source for an electrolyser, and could fry the welder because it isn't designed for this sort of thing.
