400 watt ZVS induction heater

In this video I 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.

What type of ferrite core? EI or O or I ?

[PeterH84]

@TeravoltOrg Its from a TV flyback transformer. The core is [] shaped, with a small air gap on the secondary side.

can u melt the steel to liquid ? with this device how much power is required to operate this

[PeterH84]

@Morderesh No, it's not possible to melt steel with this heater, it hasn't enough power to do that. The power required is around 420 watts.

do you use any closeloop control system in this setup?

[PeterH84]

It's just a toroidal transformer connected to a rectifier, after that a few caps parallel and than connected to the ZVS driver. The ZVS driver is connected to a coil wound around a ferrite core, 4 + 4 turns. The other side of the core contains 4 turns, connected to the work coil. The transformer itself is 900 watts, so I should be able to optimize it.

mmi still didnt succed my zvs yet;

i used n-ch mosfets FN1016

the capacitor is the best i have,it has 1.68µF; its big and healthy and so well working !

but my zvs doesnt even charge it, i measured the voltage on the capacitor, and still no current ! no voltage is witnessed !

and the controling coil that must be between 40 and 200µH heats up very quickly to even make smoke !

what do you think i should do;? nothing that even the transistors starts to heat; not as bad as the coil:yet they do

[Arjoonmoal]

@PeterH84  you can do it. justw insulate the steel with glass fiber

[xtalgrwr]

This there a schematic for this unit??

I'd like to study it, if I may.

Many thnx.

[05faber]

if in doubt, put a spoon in it lol

very nice work making this, would you be able to send me detailed instructions on how to make this please?

[zezimashock]

ok XD

[andrewzb]

ya kinda but i still wanted to know
