looking for a dc 12 volt step up transformer. i can not find one on the internet. i asking if you would help me search the internet for one. first one to post a link with this will get the points. needs to step up to a maxmium of 96.

dc can be transformed if it is alternated off and on.

Turning the 12 dc off and on is called pulsating DC. Pulsating DC has many high frequency components. You will burn out a transformer with pulsating DC.
Alternating Current, AC, is a pure sine wave.

If you want to step 12 volts AC to 96 AC, you need a transformer with a primary to secondary winding ratio of 8. You then connect the 12 volts to the secondary, and will get 96V at the output. The most accurate way to do this, is go to a transformer shop and ask them to do this. They will ask you for current requirements. If this is not an option, go to a hardware store and ask for a 120V to 15V (or whatever value is closest) transformer. Keep in mind that while voltage is multiplied, current is divided, so that at the end you get the same power. So, if you have a transformer with n=8: V=12*8=96 volts I= 110/8=13.75 amps

DC cannot be transformed directly.
First run it through an inverter, do the step up transformation, then rectify it again
