firfirik Posted August 5, 2006 Report Share Posted August 5, 2006 Hi ,Iwanna know if anybody has built this circuit..Does it work?If someone built it, would you please send its constructed photo?thanks.. Quote Link to comment Share on other sites More sharing options...
ante Posted August 16, 2006 Report Share Posted August 16, 2006 Hi firfirik,Welcome to our forum.This circuit originates from an Elektor magazine (and book); I don’t remember which but its many years back. I don’t see any reason why it shouldn’t work.Hope this helps! Quote Link to comment Share on other sites More sharing options...

I don’t see any reason why it shouldn’t work.Hope this helps!Thanks for replying..it is very kind of you :)I'll try it for I've found a 0-42VAC output transformer..Also I'll send a detailed study about this project for I haven't found one..

ante Posted August 23, 2006 Report Share Posted August 23, 2006 Hi,A few things to note:I don’t believe the voltage will go all the way down to zero, perhaps 0.5V but that might not be important for you? The resistor R12 kind of decides the minimum voltage here and this resistor should have a 5W rating. R11 (the shunt) can be made by paralleling two 0.15R (2W) since 0.075R is not easy to find. The LM10 is a slow horse and the transistor T3 protects the circuit from destructive over current. Someone has written 42V on the diagram but the text says 36V transformer and the later is the correct value I believe. ;) Quote Link to comment Share on other sites More sharing options...
