EMMC and big TCs and 1.2kw flyback and IGBT Qs
Hello Everybody
Recently I have been thinking of my biggest TC yet. I have planned to
make it the dimensions to 24(diameter)*80(height) inches. I put the
values in to WinTesla(my thanks to the creators), turned the AWG down to
10 to get about 700 turns. Then I look at the amount of wire I need and
practically have a heart attack. 4500 ft of AWG 10?? That is like a few
hundred USD. My question is, have I made a mistake or is these something
that I am missing?
Question about MMC's: How is it possible to use such low value voltage
strings in a EMMC(like only 50% more)? I have seen the voltages on a
5/30 NST ratchet up to 13kv with only 1nf, unless it is just that my
multimeter, which is not true RMS, can not read the voltage right with
non-sines.
My current(NPI) flyback driver uses a simple push-pull MOSFET config. It
is approximately 1.2kw and runs off of only 40v(!!!). I am using a
multivibrator. What is the advantage of using a resonant topology to
drive a TC primary to just having the multivibrator run at the TC freq?
Another question, is it possible to use a arc welder as a _high_ power
supply?
Does anybody know a good mail order source for IGBTs? I have recently
acquired a 600v xformer and am hungry to drive it.
Much Thanks
Bryan
