    12kw Induction heater

    Several years ago I built a 12kw induction heater for a blacksmith. This unit was able to melt and boil steel within seconds. For those of you who do not know what an induction heater can do you are in for a real treat.

    The tutorial along with schematics is here.

    Here is a
    of a small 3kw unit I built.

    I tried to make a tutorial for both beginners and advanced users. When I first got interested in this there were very few articles explaining the theory. One of the problems many face with higher power units is an understanding of why these circuits blow up at the higher energy levels. For those who have not seen it yet, I've included many oscilloscope tracings showing "bad" waveforms and how to diagnose the issue. Eventually, I sold my unit to a blacksmith who now uses it to make swords.
