I have a center-tapped transformer which outputs 12V-0V-12V. I was wondering what is the differences between using one full bridge rectifier and two to generate a positive and a negative DC rail.
Consider this schematic:
It uses one full bridge rectifier and uses the center tap directly as GND.
Consider the second schematic (smoothing caps omitted):
Besides from using more diodes, what are the differences between two approaches?
