1. Transformer (greater then 12-0-12 rating)

2. Rectifier (Bridge Rectifier)

3. Filter.

Now, for the Rectifier I'm quite sure that I need to use the Bridge one because of its Ripple factor and greater Transformer Utilization Factor.

But I'm clueless about the Filter part, Now I need 15V as output, so what combination of Capacitor and Resistor should I use?? How do I determine that?? And I only know that 12-0-12 transformers are available, is a output voltage of greater then 12-0-12 transformer available too?? Please help.

Thank you
