Besides the obvious phasing issues, is there any reason why I shouldn't
parallel 3 12kv/30ma NST's? I'm looking to get over 1kw output and can
get some NST's cheap right now.
Also, have any of you used polystyrene for your caps? It's seems so
much cheaper to use about 93mils (a sheet of 1/32 and a sheet of 1/16)
to get the required capacitance to match your transformer than going the
MMC route? Any comments?? BTW, in order to meet the .0198 uF
requirements of matching my xformer, I would use about 58 plates of
8"x8" flashing and 2 sheets of 1/16 and 1/32 polystyrene available at
McMaster Carr for a total of 26 caps in parallel which a capacitance of
.0198 uF and a voltage rating of 46K. This is approximating
polystyrene's dialectric to be 2.2 and about 500 volts/mil.
This setup would fit in a 5 gallon bucket that could be filled with
mineral oil or transformer oil (if your lucky enough to have some on
hand).
Am I making a stupid mistake here??
All comments appreciated...Thanks,
John
