I can always get a lot of PC PSU's but they are never voltage adjustable...If I smoke a few in experimentation no problem...but still would rather avoid it if I can..
Trouble is, although they may have stable outputs...they are always different voltages..by 0.3 volts or so variation...This batch of 4 I picked up this morning vary from 11.3 to 11.9 volt open circuit on th 12 volt line....OK...so cheap DVM so maybe they are all a little higher...but at least I would be expecting the error to be consistant.
I have been running three in series to give 34 volts to run an iCharger 3010b...but was wondering about running another three in parallel to up the current.
OK...so i could choose the PSU's to string together to voltage balance each string to give as close as possible voltage...but was wondering about balancing the parallel strings as is being done with Meanwell PSU's
I believe diodes are involved and I would imagine they go in series with each string...but that is where my knowledge stops. So probably high current rectifier types, stud diodes or similar...but???
Anyone shed any light on how to balance up these strings...or not bother just parallel up the series strings and hope of the best?
