I need a power supply that puts out (max.) 60V at 13 amps. Ripple is not too important, as long as it is no more than 0.5V or 1V. I don't want to use expensive transformers, though. Is there a switching mode that can run off house current? Both these requests are similar enough to use the same basic circuit. The power output at 20 volts, 40 amps is 800 watts and the power at 60 volts, 13 amps is 780 watts. The power input will be higher due to losses, so plan on 1,000 watts input (8.3 amps at 120 VAC). Since the big deal for me is the transformer design, I will do that first. I am using the Magnetics, Inc., manual for ferrite cores.
