Hi again Steve,

As far as I can tell.  The initial condition of 10V on the primary cap must 
be forcing 10 / 0.03 = 333 amps through the primary system also as a 
phantom initial condition.  That false initial current is messing up the 
system's energy!!

So Indeed I think the model is now completely wrong!!!!

Sorry bout that!!  Darn computers!! :o)

I thought it was just a little too good to be true :-((  I still have 
another idea so I will try that next.  I still think there is much promise 
to this area of study even if it does have a few traps lurking ;-))

Cheers,

         Terry

Hi Steve,

I had the 10V in there to use as an initial condition so I could ring down 
the shorted primary system to determine its stand alone resonant 
frequency.  I had since forgotten it.

You are correct, this initial condition seems to be having some odd affect 
on the model!!  If I set it to 100V then I get 5 millions volts on the 
output!!!

I will try and sort this out but it does appear there may be an error in 
the analysis!!

Cheers,

         Terry
