Answer 2

An appropriate transformer will do this. The ratio of coils needs to be about 1:18.3. Make certain that the current-handling for the transformer is rated high enough fo the application.

Answer 3

Here you go with a 15W inverter. Just scale it up for 220V by using a different transformer. If you need more power then Google it for yourself. Why you would want to do it yourself is another matter when you can go to a high street shop and get one ready made much cheaper. Look for "inverter".
