looking for help..i have step down xfrmr-115v to 30 vac,
in the form of miniwelder model 73(??). 50 amp in the secondary(good one heavy and copper). i would like to use it to make 30v pulsating dc and hook up a doubler ckt also.
producinc 60v pulsating dc. i have 80amp/1000 v fullwave solidstate bridge rectifier. my question is what capacitors do i need and what capactence..and how to figgure the size(ufd)..schematic would also help. (also is it possible to get 15vdc out w/o tapping the secondary?)thanking in advance for your help., art

if your present model is with centre tapped secondary (30-030) and uses 2 diodes as full wave, then it is possible to use end to end as a single winding and use the bridge rectifier, that employs 4 diodes instead of two in full wave. Perhaps you may google to see the full wave and bridge schematics. capacitor based voltage doubler cant deliver the type of current , you need fro such heavy transformer.
