must signigicantly improved of modified from what you tell me.
You need a low-voltage lighting transformer (rated 200W or more) and a means to chop the voltage at the primary. The transformer will be by far the biggest expense.
A common way to do the chopping is to use a Royer oscillator. Vibrating coils are were common in early automotive radios; they're still used in cheap inverters.
Link below has some circuits.
A more efficient way would be to step up the 12V to 120V DC, using a flyback topology. You still needs some coils but you could run at much higher frequencies and avoid the bulky transformer.
