Maybe its possible to boost the power of a multi-transformer TC by:
1)Boosting the capacity of transformers by increasing 60Hz input frequency
2)Spark-gap quenching by cutting input power
3)Supplying gap power at greater frequency
The cost:
1-addional spark gap, making a 2-spark gap (or ping-pong)excitor
2-scr's to alternate 2 of your transformers
1-capacitor to be placed in-between transformers
1-logic driver chip, like a flip-flop
1)...
While contemplating power supplies, I came across a neat driven inverter
based on SCR's. Basicaly a SCR bridge driver.
Consider two neon-type transformers connected in series, the center-tap
wired hot. The other two ends connect to SCR anodes, and both SCR cathodes
to ground. A capacitor is between SCR Anodes and transformer arms.
Now just alternately pulse each SCR. When one turns on, the capacitor SHORTS
the other SCR, turning it OFF. If you alternate 240 Hz, (and if it could
work with triacs?) you could get 4 times as much power? Maybe even 600Hz
and 10X!!!
Why not? Aside from the fact the transformer wasn't designed for it and will
get hot, but the cores probably good at 240Hz, right? You can only stand 30
seconds of ozone anyways?
2)...
Consider a multi-electrode spark gap, fed by independant transformers (like
above). When the logic circuit sensed a gap fire, it turns on the alternate
SCR, removing power to the energized gap's transformer and energizing the
alternate transformer and gap. The gap would cool faster, like with a
synchronous interuptor, right? Solid state, no moving parts!
3)
Your doing the above 2 elements a few times 60Hz, so you are increasing your
effective energy delivery rate, right? Now you need to add more HV caps :)
SCR's are cheap. You would need a low ESR cap to zap your transformer
primaries. It would take a beating. Maybe a good schottky across the
transformer to let it free-wheel, If you use a small cap.
