Details of this Royer circuit electronic driver for flyback and other coils are here. Here it is used with a 1+1 turn primary on the base of my 18 inch coil.

This is my earliest use of electronics to drive a solid state Tesla coil using SIDAC’s in place of a spark gap. It is a proof of principle coil rather than a big performer. “Continue reading” for more details and photos. Continue reading
This is a SIDAC IGBT Spark Gap (SISG) module. SIDAC’s are used here as the triggers for IGBT’s to simulate a DC spark gap developed by Terry Fritz here.

A variac is a variable transformer used to supply adjustable power for many projects and is invaluable. They are also expensive as they are large and heavy. Here, I explore the solid state option which may be preferable in some situations.

This was just a quickie to demonstrate that one can get sparks with a hand cranking a Tesla coil.

This project describes building two identical Tesla coils and driving them with a solid state driver. “Continue reading” for more details and photos.
