DIY Induction Heater

inverter uses a half-bridge topology. I feed 120vac into a voltage multipler. In this video I have placed a steel nut in the coils on a high temperature ceramic plate. I take the inputs up to 100vac and 20A. The tank current was somewhere near 400A, which exceeds the rating for my capacitor bank. It does not take long to see the nut start sparking and boiling off molten steel. I run the unit twice; when I am finished the steel is fused with the ceramic. ... Induction heater electronics ...
