Hi everybody!

I'm studying Automobile Engineering and I'm not fluent in electric but my project is about electric!
"220VAC to 0-120VDC and 0-15 Ampere Variable Power Supply control by Arduino" to check automobile equipment. I use a transformer to convert from AC to DC, Arduino display Voltage on LCD but I don't know how to adjust Voltage and Current (maybe potentiometer makes Voltage, current fluctuate), reduce noise, heat ventilation...
Could you give me the solution?
Thanks, Phuc

 

Why do you need 120vdc to check automotive equip.?
Is it 0-12vdc you need?
Current is dependent on actual load.
Max.

 

Are you going to build this,or is it a homework problem?

Max,
First, I need 24VDC 3A and I can solve it but my teacher asks over 100VDC (variable 0-100VDC) and 15A (variable 0-15A) and I faced problem as above

It's a project problem AK!
