I have a 15volt 25 amp SMPS that I would like to convert to a +/- 15
volt power supply. I was wonder if I could do this by adding two
diodes to the present two diode full wave rectifier circuit to turn it
into a bridge. Also the power supply seems to be operating at about
25Khz, but the diodes are standard recovery. Would there be any
benifit to switching to fast recovery diodes.
