what mosfet to use for an induction heater
Last edited by a moderator:
I favor thermionic power tetrode or power pentode forced-air cooled vacuum tubes for high-frequency induction heaters. I did have some experience working with a low-frrequency, inducution-heated, pressure welder installed in a high-vacuum chamber at the General Electric Evendale Plant sometime in the previous century. At that time GE was interested in constructing integrated, monolythic, blade-to-shaft turbine assemblies, what they called a Blisk. Catchy name, huh?what mosfet to use for an induction heater
Is MOSFET a must? You have an option of IGBT's too.what mosfet to use for an induction heater
Do you have a link to valid information that supports your assertion?Get one that is not effected by field radiation. Some new transistors are designed to fire when a field is a certain strength.
What?! You want the poster to present with objective and verifiable FACTS with a link to VALID information? Or as Homer Simpson once said, "Facts, shmacks. You can prove ANYTHING with FACTS! Facts are meaningless. You could use facts to prove anything that's even remotely true.”Do you have a link to valid information that supports your assertion?
Wonderful! I don't know how you find the time to dig out this information, but it is much appreciated. Can you now attach a Zip-file to your next message that contains all the power IGBTs that might be useful? @ramussons suggested this in post #4 but nobody responded.Hello,
Have a look at the attached Zip-file with an overview of the IRF mosfets.

Thanks!Hello,
Here is an overview from Rohm on IGBT's .

Induction heating "cook tops" are very common in this country for more than a decade.I notice that induction heating cook tops are becoming popular. I would love to have one of those, but I have heard they work best with cast iron skillets. Or do induction heating stove tops require special pots and pans and skillets?
So, if one actually wants to build an induction heater what's the best to use? 2N7000 mosfets or 6L6GCs power tetrode vacuum tubes?Gee, whiz, folks. I completely forgot to check into which forum the OP asked their question! The Electronics Homework Forum, of course. We ARE NOT supposed to give definitive answers to questions asked there. Guidance and pointers to the right direction ONLY!
So, forget 2N7000 mosfets, 6L6GCs power tetrode vacuum tubes, or any of a plethora of high-power MOSFETs (or IGFETs) and IGBTs. Forget about parametric searches on DigiKey or other distributors. Just forget any suggestions made here with regard to specific devices, circuits, best wiring practices, selection of components, yada, yada, yada. You will only need those later if you actually decide to build an induction heater. What you need to do NOW is make Google your best friend to help you research "the how and the why" of induction heaters, "the when and the where" high-frequency, mid-frequency, and low-frequency induction heaters are best used.
The question is not which component is "best" for an induction heatre. Ther question should center around the requirements for the component in terms of e.g.;So, if one actually wants to build an induction heater what's the best to use? 2N7000 mosfets or 6L6GCs power tetrode vacuum tubes?
