Solid State Tesla Coil

My coil is a self resonant H bridge design.  The design is based on the one by Justin and Aron of

I use IGBTs unlike most people who use MOSFETs.  I have found IGBTs to be more reliable and run cooler then most MOSFETs running at the same levels.

Max spark length to date is 21" to ground at 140v input.

The coil is mounted on a custom made oak base, which took me almost as long to make as the coil itself did!
