Hi all.

Seems that this might just work. Obtain a piezo inverter and measure the off load frequency.

Then, wind a Tesla secondary resonant at this frequency, with a 150 or so turn primary with capacitor to Gnd.

has anyone tried this?

regards, -A

''Obtain a piezo inverter'' is what I would call an impossible part.

And if I had it I would probably find much better use for piezoelectric transformer.

Tesla seconday is quite happy driven with $20 bridge of mosfets.

Proble with Piezo inverters is that they are normally low power. I designed a 35W Piezo inverter for work and that was far larger than any of the others I've ever seen - most tend to be in the 3-7W region.

What do the Piezo inverters look like? I have never seen one before.

I googled for Piezo inverter and I got this Link2 which is the inverter that I designed! Woot!

Link2 This page has some pictures of typical inverters on page 5
