I realize this is not exactly 100% wonderfully
clear, but let me describe what I think will happen.
The stars above represent the electrodes on the RSG.
The + and - on the bottom drawing are continued from the
+ and - above.
There are 4 electrodes on the rotor - the electrodes at
0 and 180 degrees are connected togeather and insulated
from the electrodes at 90 and 270, also connected togeather.
In the position shown, the resonance caps will be charged
+ on the bottom, - on the top when the gaps fire. After
rotating 45 degrees, the resonance caps will be charged
- on top, and + on top when the gaps fire.
I am only calling them resonance caps because in each
presentation all 3 caps are in series but the big 2 uF
cap is not changing the resonance picture much,serving
as an energy reservoir to recharge the smaller caps
in the opposite polarity.
In a way this is sort of like a 2 stage Marx bank, at
least from the point of view of the primary,
Does this make any sense at all? The only downsides
I have thought of is if the resonance caps fail all of
the energy in the storage cap will dump into the short,
possibly creating some excitement.
