Hi Harry,
Say, why don't you shape a work coil into a Tesla primary and wind a
secondary to match your operating frequency. At 25KW continuous power
you'd have a beautiful whipping, hissing, spitting, display. I built a
FET driver that operated at 8KW continuous which produced a 4 foot
sheet of electrical flame that sounded like hell's welding torch.
Several years ago I combed an induction heater surplus yard with just
this idea in mind. Do it, do it, do it.
Zap,
Mark
