thanks guys. Yes actualy i know the difference between half wave and fullwave. And for the guy who said it would not work well, i built this circuit and obtained good results. What i wanted to know is that what dirreence in the output one would get when using centre tapped and normal trans. thanks to all of you. 8)

thanks very much friend! any other ideas and suggestions are welcome!! Thanks again

Dear Friends I am doing some small research about power supplies and found this one interesting: www.redcircuits.com/Page36.htm I have some questions if you don't mind: Why is it that a centre tapped transformer is used instead of a normal transformer? Is this only to use two diodes instead of four or because of any other particular reason? What is the difference between linear and non linear power supplies please? Your answer would be greatly appreciated Thanks in advance. Regard, Steve Malta ;)
