MMC cap questions
Hi all,
My NST farm is dwindling, and I'm looking at pig-power. I feel confident in
my knowlege to move up to the multiple kva niche and start experimenting.
Though I want to choke the system down to only ~2 kva to start with, then
move again as I learn more. 8" coils are much more expensive to wind than
2" coils ;) Mostly, I want a more robust power supply, but having more
power is always welcome. Something externally ballasted will give me the
ability to run 2kva or 20kva.
Now, I currently have an 80nf tank cap (16 strings of 11) MMC. If the
panasonic caps go nuclear at ~3A RMS, I think I can push 32A rms without too
much trouble. Think this will stand up to a pig's abuse? Voltage-wise, I
know it's under-rated, but I can always use a small step-down tranny on the
240v side to lower the pig's output to 12kv. Only have to reduce the line
voltage to 200v (maybe a heater element in series to burn off some voltage).
What concerns me is the RMS current. The caps take over-volotage in
stride, but over-current is murder on 'em. And I'd hate to burn up $230
worth of caps by not knowing...
