power supply, I have only common cathode diodes
stefon:
stupid question... I have only common cathode diodes schottky diodes.
Can I do something like that to get symmetrical power supply?
MagicSmoker:
You sure can.
stefon:
well, this is how it looks... "-" is weird... why?
edit: OK, I think I know.... reverse voltage of one schottky diode is only 30V and when I connected both 12V trafos, there is 40V peak to peak

Looking at the scope that explanation doesn't make sense to me, but I can't explain why just 1 half of the -ve's cycles is floating about either. :)
Jwillis:
Looks like you have one bad diode that isn't recovering very well.
