yeah you're right.... its only a year 11 class project and we don't really know much about it yet... we've only received a couple of notes on linear voltage supplies, about like the different stages of transformation... rectification... filter capactors and finally regulation... our teacher went in depth with everything except the regulation... which i reckon is the most important... i've had a look around for regulation curcuits and found out the switch mode is the way to go, so i googled it and found a couple of guides that start off really simple and then just jumps straight into it.... any ones you can recomend? and also... we're supposed to get the most out of the transformer... so yeah i meant 8.88A... not 10A and the 25 volts comes from 18RMS * 1.414.... same with the 50V (36RMS * 1.414) at 4.44A
thx for helping
