Is it feasible to parallel bridge rectifiers for the purpose of increasing the current capability?
I need to feed about 25 amps output from a single phase power supply and have on-hand some 8-amp bridge rectifiers. I’ve never seen this done before. (Maybe a good reason why?) Wondering if I can parallel 4 of these to make a 32-amp circuit.
I’m aware that attempting to parallel a pair of power supplies will end in disaster as one will try to hog the load and burn itself out. Will the bridge rectifiers do the same? Thought I’d ask somebody who’s tried it before I enter into another school of hard knocks.
Never mind... found the answer and it's just as I suspected. One fellow likened it to paralleling 2 relays. One set of contacts will always close first, taking all the current and burning up. Same with the diodes. Even if they're perfectly matched, it's doubtful they'll stay that way. (Off to Digi-Key for a heftier component.)
