Hi Finn,

See these links for the explanations:

Look for "DRSSTC" stuff.  Basically it is a low voltage current source 
added in series with the tank circuit that drives current into the 
primary.  It rings the L and C up to high voltages and currents while the 
voltage on the current source stays low.

Since my fist idea went up in modeling flames (POOF!!), I will now try the 
long ring up time approach with low coupling to pack as much energy as 
possible into the primary...  It's cool stuff!  Probably the future, even 
if I can't make the drivers cost less than $2 ;-))

Cheers,

         Terry
