Guest 2old4digital Posted May 21, 2006 Report Share Posted May 21, 2006 What is this curcuit for? Are you try'n to fix or copy? Quote Link to comment Share on other sites More sharing options...
pyroboy Posted May 21, 2006 Author Report Share Posted May 21, 2006 I am trying to copy it, I have already made the PCB! :)It's a voltage inverter. It came with two cold cathode lamps.It takes 12v and it gives 680v I think but I am not sure about the last one. Quote Link to comment Share on other sites More sharing options...
SM2GXN Posted May 21, 2006 Report Share Posted May 21, 2006 Hi pyroboy!The component that are marked as capacitors are probably ferrite beads and they are used as filters but there is two disc ceramic capacitors one each side of these beads, if there is a white ring around them it is diodes but I can't see any on the picture, The black thing is an inductor probably used as filter too, together with a capacitor it will make a lowpass filter, maybe for the dc voltage into the pcb.A small high voltage transformer like that is not easy to wind, you'll need a very very thin wire ;) Quote Link to comment Share on other sites More sharing options...

pyroboy Posted May 22, 2006 Author Report Share Posted May 22, 2006 I m trying to learn but I have to learn the the small parts first and then I will make my own transformer.What kind of characteristics does a transformer have?How will I ask it from the "electronic" shop Quote Link to comment Share on other sites More sharing options...
