Today, let's rewind the faulty transformer of my 12V 50A 600W switching power supply. I wound it partially the original way (with some original shortcomings), just using copper instead of aluminium, and splitting the secondary into more parallel wires, leaving the original design of the primary. Of course it could be redesigned much better, fitting higher cross section of copper into it to reduce the current density. It could also use many more of thinner wires to further reduce the skin effect. The returns that waste space could be eliminated by winding each section in two layers. The secondary could be a copper strip which is more space-efficient for high current low voltage windings.
