I have lurned a little pspice 9.2 and have designed an optimal tesla circuit with a voltage multplication of 3000. Now I know that duplicating this in realty is a differant story but couldn't I make some thing that could aproch this like 1500. I have seen some secondaries that have spaces in the windings that essentialy reduce distributive capasitance has anybody tried this?

Generally the increase in "Q" using spaced windings (to reduce proximity effect and self-capacitance) results in lower inductance/resistance than a close-wound coil, and once even a tiny bit of corona develops the "Q" plummets. Try your simulation with 100 kOhms from topload to earth, even 1 MOhm is significant.
To all of this add the most difficult part of TC simulation; how to parameterise the arc impedance?
Some aspects of TCs are best simulated (SGTC/DRSSTC etc. - two coupled self-resonant circuits giving the 'double peak' or 'frequency-splitting' for example) mostly it's best to try in practice to get a 'feel' for things.

Check out Terry Fritz's paper on "Modeled Voltage and Current Waveforms in a Tesla Coil" Its available on under Terry's section and provides a good insight to modeling a tesla coil (spark gap type) in PSPICE.

Teravolt, Do you mind posting a copy of your pspice model so we can all play?
Here is a copy of the one I used. It was made by Terry Fritz for my 300 BPS sync roraty , back when I was working on Equal bangsize at that breakrate. You can always delete the extra electrodes for 100/120BPS service. Schematic file here: ->

thanks everybody for seting my cumpass pointed in the right direction. I am using mesured and simulated data to get my model to work. I am tesla and electronics savy but not to savy with puting stuff on this site like files and folders and scematics but I am working on it.
