Terry,

Coincidentally I've been working on a similar idea. My plan is to chop out
cycles of gate drive as needed to keep the current below a user defined
limit. ut I shied away from putting an embedded controller in the thing.
It's not so much that I think it's a bad idea (although there would be some
serious "issues" if it crashed mid-burst) but more that embedded controllers
and DSP are my day job. It's a relief to escape to some 1970s style analog
electronics where the chips have 14 large pins that you can actually see ;)

I originally tried to use nothing except 555 timers in my SSTCs, but I have
got more adventurous now, with a whole alphabet soup of 4046s, 4011s, 4013s,
LM339s, TL074s, TC4429s, etc.

I'll publish my current measuring and control circuitry once I've actually
tested it all on a coil and seen that it works.

I've updated my website at http://scopeboy.com/tesla/ with the DRSSTC and
induction heating work.
