In this video I will demonstrate my improved ZVS induction heater. I isolated the work coil from the rest of the circuit by a ferrite core, it has 4 + 4 windings on de primary, the secondary has 4 turns. I've done this to protect my ZVS driver, and it works. I already shorted the coil many times, without any problems. The mains transformer used is custom build, it is able to output a max of 900 watts, meaning there is more then enough room for improvements. ...
