Hi to all!!!!
Hi am try to find methods to construct Laboratory power supply(0-30V @ 5 Amps). But the power that the series pass element has to bare is (30*5=150 Watts). So i started designing with bread board and Enjoyed the magic smoke all the time because of Series pass transistor and Some potentiometer(due to current control) went to breakbown..
So the finding out of this is
1) I have to build pre regulator with SMPS techniques.
2) want a technique to build current control Knob..
I will be thank full if you prescribe the textbook which describes the design technique rather than university Text.
