Hi, just a speculative thought - has anyone ever tried (or would it work)
to use high power thyristors to replace the spark gap in a standard TC? I
have seen modern "puck" thyristors capable of switching over 2kA at over
8kV continuously and dV/dt ratings of several thousand V/us. I may be
missing a vital point here - other that the extorsionate cost of the
things!)? One such problem might be the leakage current making it very hard
to get the tank cap to charge.
It would have to be a BIG coil I suspect to get the resonant frequency down
as much as possible (a few 10s of kHz) thus reducing the dV/dt enough.
just a thought...
