Induction coil driven Tesla coil driver information



Original poster: "by way of Terry Fritz <teslalist-at-qwest-dot-net>" <zardoz-at-albany-dot-net>

Hi,

I recently purchased a nice larger induction coil that I
would like to use to drive a small Tesla coil (TC).

My question concerns solid state drivers for induction coils (IC's).

The IC i purchased has a beautifully made interruptor that was
constructed by scaling up a similar interruptor found in an old
text. (according to the skilled seller, and his work is a work of
art.)

The problem with this interruptor is it was made to achieve maximum
spark length, and it does this very well. It is heavy and slow, I
need a much faster interruptor to light geissler tubes etc. (This
wont vibrate when hooked up to a geissler tube) and I believe I also
need a faster interruptor to power a Tesla coil (shorter hotter
sparks of the type produced by IC's intended for wireless work.)

Photos of this IC and some specs can be seen at:
http://www.albany-dot-net/~zardoz/inductioncoil.html

The coil can be powered from a 12 volt car battery.

I need information about how to build a solid state driver for this
coil. I must admit I do not have alot of electrical knowledge,
especially for reading schematics etc.

I have found some plans at:
http://www.geocities-dot-com/CapeCanaveral/Lab/5322/hv2.html

But attempts to contact this person received failure notices.
(Most of the pages still work)
He has some solid state drivers for car coils that I would like
to adapt for my coil. I noticed that on one of the schematics, he
has 12 volts+ in, but doesn't show where the 12v - goes (assuming
a car battery is used, what do you do with the 12v-? This question
I'm sure will illustrate my lack of electronics knowledge.

Any help and advice will be greatly appreciated.

Thanks,
