Hello all,
I am in need of some help. I am in need of a transformerless power supply will allow me to have a universal ac input 110/220 volts and an output of 12 Volts at 3 amps. I had a couple of old monitors around the house that were auto switching. I traced out the ac portion of one of the circuits.
The capacitor is a .33uF not 100nF
:?: I don't really understand the circuit but it works. Now I need a way to reduce the high voltage dc down to 12 volts at 3 amps.
This will be used in a prototype portable, high power, led light source that can be used in developing countries.
Thanks for any help
Patrick
