Greetings All,
I'm trying to build a voltage multiplier that is fed by a audio output transformer (273-1380). My source is a 9 V battery. My question is how do I convert the DC to AC so that it will work in the transformer? Can I make a square wave generator out of something like a 555 to feed the transformer or something like a lm358 or some other op amp? I don't quite understand what an op amp does in inverting mode. Is the output on an inverting op amp a form of AC?
Thanks,
JJ
