Decided to build a DRSSTC Bi-Polar Tesla Coil
just to see if it would work and to be this first!
· The secondary is 48 inches by 12 inches using 20 AWG magnet wire, 20 pounds that is. The bridge is using 200 amp 1200volt IGBT's. Rated: 200A IC, 1200VBVce,+-20V Vge. The primary is 1.25 turns of 4 AWG stranded insulated wire and yes after a run it gets hot. There is a great deal of primary current on the puppy indeed!
· The Fo = 85.666Khz. You should keep the DRSSTC's under 100Khz due to limitations of IGBT's switching speed.
· The coil is one of the loudest DRSSTC I own and a crowd impresser; furthermore, hearing protection is required.
