Re: [TCML] very good simulation for peak currents

No, actually it is very good.
For example, set for Stephen's coil using the Java graph, V=21.2kV, R=15mOhms, C=12nF, L=62.5uH. The graph result shows 294A. 

Ip = Vp x sqrt(Cp/Lp)  = 21.2kV x sqrt(12nF/62.5uH) = 294A
Javatc shows 294A also (transformer section: output titled Instantaneous Current). 

Like any program, it's a matter of getting the inputs real.

Also interesting is the cap voltage graph (click the check box).

With the sec missing the estimates will not at all be accurate.  The sec of
course absorbs a lot of the energy and prevents high peak
currents and potentials from blowing your pri cap.

He is using caps that are not designed for high current impulse duty (100%
voltage reversals).

Also, the sec will reflect energy back into the pri which can cause
constructive and destructive interference patterns in the energy flow.

Interesting site for the basics but it does not have enough information to
apply to a Tesla resonance transformer.

Hey guys (and girls ;-) )I found a very good site with simulations of the
peak transients etc in a RLC circuit - very easy to use...

http://www.coilgun.info/mark2/rlcsim.htm

it shows the peaks and decay time for any Resister Inductor and Capacitor
in a simple parallel resonant circuit.
it ignores any energy absorbed by the secondary of course.. ;-)
