DIY Induction Heater

We have featured DIY Induction Heaters here before. There is something about heating a big chunk of metal with no contact that is so appealing. Uzzors2k has a great write-up about his experiments with his Induction Heater, it is filled with trial and error which we can all learn from. 

"To test my new driver I had a large work coil and tank capacitor already built for a previous induction heater project. The tank capacitor was made up of 50x 22nF and 50x 12nF mini capacitors I purchased cheaply off ebay, giving a total of 1.7µF at 600V. So far I’ve had 3 capacitor failures, all of them with the small 12nF ones. Other than that the bank has held up well and doesn’t seem very lossy. The most difficult component to construct was the matching inductor, which dissipates surprising amounts of power due to the large current flow. After a few failed attempts I had to use 32 strands of 0.3mm magnet wire, wrapped together as litz wire. Even with just 8.6 milli-Ohms of DC resistance I still had to use a fan to keep the inductor temperature low enough."

    i am also hobbyist in electronics, do i have a diagram and the specs of this gadget. It would be most welcome if i could have the whole thing. THank you very much

    […] iron incident. But if you are careful this could be an interesting project. We have featured a few DIY induction heaters here before and the results are incredible. Not exactly the safest project to create but there are […]

    Dude that’s really amazing. I totally agree with you on the “There is something about heating a big chunk of metal with no contact that is so appealing”. I am only 13 yeas old and have no access to these parts (yet)😄 and being 13 my parents don’t think I have the responsibility to handle that doohickey. And I’m I geek as I like poking around with wires resistors capacitors etc. I love taking things apart and removing the comments from the circuit board yet of all the parts I acquired none are the right kind oh we’ll il kept digging.

    I have a question. why we have to first decrease 220V urban power via a computer power supply transformer to namely 5V or 12V and then increase it to 600V? isn’t good that we multiply the 220V urban power to 600V? I think in this later way, less hardware must consume. please send me your idea, because i am attempt to study about induction heating.
    thank you.
