Piezo transformers?



Original poster: William Beaty <billb@xxxxxxxxxx>


Here's something odd I hadn't encountered before: resonant high voltage step up transformers with no coils: piezo stacks. Digi-key has them: P6000-ND. They're being used as tiny fluorescent tube drivers for laptop LCD backlights. Also used as HV supplies in negative ion generators. Search on:

  Piezo transformer
  Piezoelectric transformer
  Piezeoceramic transformer

So, now we can make Tesla coils which contain ONLY moving parts, rather
than the opposite!
