That is definately not a 'Elementary Electronic Question'.
Please visit the appropriate Topic...

Hi,

You will need to build a boost converter.

This kind of converter boosts up a DC voltage using voltage switching techinics

Maxim has a good tutorial on DC to DC converters ( you will find boost converters there) and you can search "boost converters" on google.

Here is the link to Maxim:

hope i could help,

use a free runnining flyback converter . but o/p will not be a regulated one
 

This type dc convertor is posted on Rod elliot site. Just google. Also on our forum. u can change the output transformer for the voltages required by u. In the rod ellot case i think the output is 35-0-35v. also attached is conver for 230vac. Just change the output transformer winding suitable to ur purpose.
