I have a trasformer that is rated at either 28v or 30v at 8A (big heavy thing it is), and I need to make a power supply giving out 24V DC, reasonably stable, at anywhere between 0-8A (load is not going to be constant).
I know I need to recifiey the AC output and smooth it with a capactitor (which size capacitor I need, I do not know), but how would I reduce the voltage?, as the current is not a constant, the volatge dropped across a resister would not be constant, so I don't know how to do this?
Thanks
Adam
