400 watt ZVS induction heater

[TeravoltOrg]

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.

[Arjoonmoal]

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

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?

[PeterH84]

The work coil consists of 10 turns of wire.

[MOJTABASHOMAL]

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.

so you really can,

wacht ik zag op je site dat je nederlands was,

dus je kan er dingen mee smelten?

[PeterH84]

Smelten gaat nog niet lukken helaas, daar heb ik met 400 watt niet genoeg vermogen aan. Echter kan het metaal wel zo heet maken dat het rood gaat gloeien.

[zezimashock]

dus inprencipe,

zou je het kunne buigen en bewerken?

[PeterH84]

Jup, klopt. Als het roodgloeiend is dan is het stukken makkelijker te buigen.

[zezimashock]

maar voor zvs kun je daar twee transistor gebruiken?

ofgebruik je mosfets?

[PeterH84]

Ik gebruik IRFP250N mosfets. Deze en de andere benodigde componenten heb ik bij Conrad besteld.

[zezimashock]

kan je nog wat andere aanbevelen,

gister twee bu204 transistors gevonde en die,

heb ik bij een hv expirement bijde opgeblazen.

[andrewzb]

what language were you speakin its looks cool is it german?

[zezimashock]

dutch XD

from the netherlands

[andrewzb]

nice just some random comment thx

[zezimashock]

where you bored?

[andrewzb]

ya kinda but i still wanted to know

[zezimashock]

ok XD
