At Maker Faire KC 2013, playing "Sail" by Awolnation. The MP3 is playing in the background, but it did not play well on video.
This is an audio-modulated Dual Resonant Solid State Tesla Coil (DRSSTC).
Pulling around 2Kw,
Full bridge of CM300DY-12h IGBT modules
400 V buss
75 KHz operating frequency
800 A peak primary current
Water cooled primary coil :)
Stay tuned, building another one.
