Double Resonance Solid State TeslaCoil uses a Capacitor Bank integrated into the Primary Coil

Daniel Eindhoven has designed an interesting new Tesla Coil, this Double Resonance Solid State TeslaCoil has a new coil design which has the capacitor bank integrated into the primary coil.  The new coil configuration has been dubbed the Eindhoven Primary.

“A new composition of the primary coil for a Double Resonance Solid State TeslaCoil (DRSSTC). It is a combination of wire and capacitors. By making the coil like this you get rid of all the parasitic inductions of the capacitor bank, it reduces wire length and saves a lot of space. Calculating the resonance frequency also becomes much easier.”
