Need to build 12dc in to 16.5 ac .5amp out ! Any IDEAS??

[marshall716]

I am looking to build the above, Because no one has one!
Looking for schematic to tweak for output.
I am not kidding, I have a use. I just can't find one.
The output can go up to 18vac and 1 amp. 16.5 is what they supply commercially as long as the input is 110vac and I want to use 12vdc.

Any help to get me on the way would be appreciated !!!!

Try this.

Sorry I now see you want AC output. I thought DC.

You could use an audio power amp, such as this, driving a 1:2 transformer to increase the voltage (you can use a 24V center-tapped transformer in an auto-transformer connection if the source voltage and load don't need to share a common connection).

The 60Hz to drive the audio amp can be provided by a small modification to this kit.
