This is the final video in my series of videos on induction heater construction. In this particular build, we implement current control to prevent damage to components such as capacitors and transistors. This has been tested over several runs and seems to work really well for a much more robust build. For construction details , please refer to the following sites:

This particular build can use any type of induction heating coil and works on a feedback based mechanism similar to that employed in solid state, Tesla coils. This particular unit has been tested up to almost 10 kW. However, on regular runs, it is usually operated between 2and 5 kW. Levitation of metals in levitation type set ups requires much higher power levels. A lot of this is in the form of wasted energy. However, heating large workloads is much more efficient.

********** Just found out that I can do away with the current shunt and get way more effective feedback from the coupling transformer. In addition, the current in the coupling transformer ia minimum 16 to 20 times lower than that in the primary tank. Check this channel to see how this is done********

The video of the coupling transformer feedback is shown here:

In summary, I hope this build comes in useful for your future induction project.  Care has to be taken during this construction, particularly if there are exposed live wire connections. Again, thank you for looking at this video. Your comments are most welcome.
