Now this may seem like an old, archaic project. I need to design, just a schematic, a adjustable/regulated power supply that is able to convert 127V - 230V AC to 0-15V with step-up of 1.5V DC with a current of 3A. Also a way to protect it from short circuit and over-current.

Links will be very helpful.:)

I sort of found a transformer that accepts 100V - 240V AC, but i need an explaination how it works. I took a Nokia charger apart and the model of the transformer is, or wat is written on it:
FM 6722

The first explaination or solution i need is for the transformer.
