"The Solid-state Tesla coil"

The solid-state Tesla coil is driven by a solid-state driver at a frequency in which the secondary is excited at. Solid-state Tesla coils do not require a sparkgap, a high voltage transformer, or a high voltage capacitor. They normally use bipolar transistors or field effect transistors (FETs). They are beyond the scope of this FAQ for now, however.
