Re: Compulsators 6 million amps of raw power!!!

First to reach resonance as you increase the cap value you need
to decrease the value of your primary inductance and you can do
it only on a certain limit. Example: imagine you have a coil 4"
in diameter the smallest primary you could practically use is 1
turn 5" diameter ( around 300 uH ) if your coil have a resonance
frequency of 200 kH you need a cap of 2.1 uF If you go with a
bigger cap you need a smaller primary not really possible (
calculated with Wintesla ). As John Freau could testified the
smaller the inductance the bigger the lost of power in the gap .
An other thing the cap you plan to use are electrolytic type not
design for pulse use and above all not make to see polarity reversal.
