1 X-Labs has recently built a huge Dual Resonant Solid State Tesla Coil! This type of large DRSSTC uses advanced power electronics which allow coil to be very efficient, compact, and controllable. While coil is still in development, we have already used it it 2012 USF Engineering Expo at very low power (we ran it at 5 foot arcs off of a regular power outlet...yes... is LOW power for this coil!). During second day at EXPO, we even had it playing music! Here are some more specific details: Secondary: 1 foot diameter, 8 foot long pvc pipe wound with over a mile of 20awg magnet wire. Primary: roughly 15 very wide turns of 5/8" copper tubing ( primary may be water cooled in future as it will likely carry over 1000 Amps at several thousand Volts!!!!) Tank Capacitor: a new capacitor is currently being built Power Electronics: Full Bridge of CM600 IGBT's controlled with a Gate Drive Transformer Power Supply: 240v Variac connected to a voltage doubler - this gives several hundred volts across bridge. There are also large capacitors across bridge to supply huge amounts of current on demand. Control Electronics: Steve Ward's UD2.1 DRSSTC controller with Primary Current Feedback and Over Current Detection Toroid: a new metal ring toroid is currently being built 1/6
2 The coil can play music with help of an external MIDI interrupter. The interrupter consists of an Arduino, Midi Shield from Spark fun, and a cheap USB to Midi cable from amazon. The interrupter signal is sent to DRSSTC through a fiber optic cable. The signal is a simple square wave is pulsed high to frequency of midi note we want to play. Whenever pulse is high, coil is making an arc and thus making sound at frequency of note we want to play. This is how coil plays music. Once this big Tesla Coil is fully functional, it will be X-Labs most impressive demo yet! This is X-labs after secondary coil was wound: 2/6
