A tour of my new induction heater. This is a work-in-progress between two designs, a low power unit which can run from 120V, and a high power unit good for 10kW or so. The control circuit is well overbuilt in comparison to the output stage, because I'm testing pieces as I build them. The major difference between this and previous models is the output network, which is series resonant, driven through a power transformer. The network response is so much nicer now, and inverter power factor is actually usable. Power output is already more than I've ever had before, especially from a 120V test. Compare the last section of this clip to my previous test.
