Re: [TCML] attn Bart DRSSTC
wow, I actually got up this morning and read some emails (grin).
Scott, yeah docs on the subject are far and few between. Most
information comes from forums such as 4HV, Tesla Universe, etc.. Most
designs copy Steve Wards DRSSTC's at his website which is linked at
classictesla. It was quite a learning curve for myself. DRSSTC's are
somewhat complicated, but not too bad (certainly not as simple as
throwing hv across a sparkgap). As they are solid state, they do require
solid state parts and yes, IGBT's are the favorites. We usually buy
surplus to keep the cost down. Cap sizes are usually larger than their
SG counterparts due to the larger inductance of the coils themselves.
Designing the coil, you want to keep it's resonant frequency low enough
to me manageable with the IGBT's. Smaller DRSSTC's can of course have
higher frequency, but the larger coils will typically be in the 40 to 60
kHz range. Thus, inductance on the sec. Anyway, yeah there is a lot of
stuff that goes into it and it is expensive. There is no doubt about
that. It took me a long time to build one which time I used to ask
questions and gather parts as funds were not always available. But in
the end, I learned a great deal and had one of the best running coils
I've ever built. It's like the energizer bunny (keeps going and going
and going). If you got to see David Blaines stunt this year in NY, note
those 7 largish DRSSTC's ran all those days non stopped. Steve and the
others of Arc Attack did a great job with those coils.
Anyway, check out Steve's designs as that's the best place to start then
just find the forums I mentioned to ask questions.

Hey Bart and anyone else who is into DRSSTC's
do you/yall have web sites involving the subject matter??
I have so much to learn and read any leads would be greatly apprieciated.
