Small high frequency coils have been built, but I'm not aware of
something like 1KW. The only person I know who's built a large high
frequency coil is Chris Swinson who was working on a high Q coil, but
that was something altogether different.
Most coils in the 1KW range might hit 500kHz at most, but it's not usual
to use such a large wire size and low turns as per the example I gave.
Even though it's probably been done before, it's still new territory.
There are of course possible drawbacks. Surge impedance is one of them.
Due to such low primary turns, there is minimal impedance in the primary
that may play havoc on the gap increasing losses, possibly some nasty
transients back at the supply, etc. Another aspect is that energy
transfer time is in the 4us range which is pretty fast. An identical
geometry coil using 26 awg at 1100 turns (same .01uF cap size) would be
in the 20us range (due to the need of more primary L to accommodate
It would be interesting to try it even if only to see how it reacts.
