Can effective piezoelectric transformer be implemented for this application?

[Marco Polo]

Is it possible to use a piezoelectric transformer to step up voltages of 3 to 12 volts to as much as 5 kilovolts? Below are more details of what I would like to do:

Input into transformer: square waves, 0 to 12-volt amplitude with frequency range of 100 Hz to 100 KHz
Output from transformer: square waves with 0 to 5 kilovolt amplitude, 100 Hz to 100 KHz

Also, what companies in the US supply piezoelectric transformers or components for making them? Any tips or advice for using or implementing the transformer in order to avoid pitfalls? Thanks!

Interesting. I hadn't heard of piezoelectric transformers before...

Berkeman, thanks for the reply. I'll check out the document more closely. I welcome any other ideas from anyone.

A new idea to me too.
It would be great for applications in which you don't want EMI, it would seem to me, as it is generally easier to screen against E fields than B fields.

I've used this before when designing backlight circuits.

Not surprisingly, digikey has some available...

Thanks es1!
