ThANKS Geenee I will take a closer look into that...
I got some good news from simulator, the capacitor idea is no good for my technic since it will not instantly accept a change in potential... buit the worst thing is that its potential is not able to flip during pulse off ...
another thing is that it has a specific voltage to charge ratio where the inductor don't...
I found that adding a coil in parallel with the secondary is all that is needed since it will act as an energy accumulator, but must be much smaller inductance than the secondary.. 100 times or so
so it allow the current to flow instantly from the transformer... the transformer must be from 3 to 10 x turn ratio... or so
The inductance around 1mh
the cell i modeled as a 1nf capacitor with 1kohm resistance
it gets up to 1,6kv at 10khz 12v 37 amps applied
