As the load changes so does the resonant frequency. This requires a PLL to lock on to it and feed back the right frequency to the power section. Some old guy on YT who made a similar system. The output of the PLL goes to a VCO which drives the Power driver (PD). The PD in this case must be a Full Bridge to drive the resonant circuit of the output coil. The PLL output is a low frequency level which will also drive a motor shaft that moves the core of the resonant inductor coil in order to change the frequency. So if anybody there wants to make this self adjusting heater then just make a block diagram to follow what I wrote. I cannot put drawings in this post. Once you make the block diagram you can also design the schematic for it. If you cannot design the schematic then it is no good if he gives you a copy because the system is too complicated for someone who does not have the skill to design the circuit.
nice description but not exactly what i made 1-its half bridge inverter 2-this topology as it called series-parallel ,has two seperate resonant frequency ,main pll tracks the paralell resonant ,another locking system sees the inverter phase diffrence and tune it with motor to have a correct power factor another advantage of this tunning system besids tracking the parallel resonant,is it can deviates from paralell resonant to have a prpoper matching its very helpful when you wanna melt steel becuase it needs very wide range frequncy to deliver the maximum power and as you said it can't be undrestood only via schematic it needs block diagram
ebay 20 amp 12-32 volt board: i figure resonance is from the 2 toroid inductors and the 2 .3 uF capacitors. the coil(not supplied) is the series resistance. I had trouble with the coil connecter smoking. I resoldered and retightened. I soldered joints that had resistance. I used a D cell for the coil form. 9 turns. A bit better still. Then I soldered the coil to the board. I put a 3/8 bolt in the coil on cardboard. After about several minutes the bolt was orange hot. I shut off the silicon valley power supply. The 1000 watt board(24 volts) might start to have problems. 2 capacitors is less resistance . ok demonstrator board. recheck capacitor - under load more?
Impressive Tuning System, but showing results comparatively the same without the tuning, doesnt provide any good information. This presentation should include how the tuning circuit provides advanced performance above other induction systems.
clever tuning system!
Oh my yard, are you here!!
tnx
So you also where searching for the "powerfull" stuff, and how to make it?
I knew I’d find you on some induction heating coil video
Can you tell me what is the frequency of the induction coil???
One hell of a machine fella.
Awesome! Could you share the circuit schematic?
Amazing...
How does the tuning system work? Very clever. Please explain. Thanks

can you share the circuit schematic and circuit components
i shall be grateful
Hi.im newbie in electronics and i have a question. Can we use all heaters as a melting device?or a heater can only be used for forging?
That's really great - thank you! By the way, how does one develop a 30KW power supply? It's not exactly 'house current'!
thanx
yeah its not household mains
this place is my uncles factory
Depending on where you live, it could be considered “a house’s worth of current” ;)
Nice project. Want to build one. Can you help?
hello can you teach to build to this heater
Hello can you share the schematics and specifications
Please , can u upload the plans and details
ماشالله
Is this doing MPPT like a solar charge controller?
Many of us need a little help or a lot of studying to understand.
Yes something like that
hello do you have a plan of this oven? can I contact you? thank you
This is not up to 30kva, 3kw only

thanx
thats true
i will prepare a video with more details and modification soon
Sooo...Plans?? I'd pay 15$ US for a complete schematic and detailed construction and parts list!
lol
XD
tuning for stable UH setting...is right??
Tuning for a proper load reflection to the inverter

Dear brother, I need 2 nos. Induction heater 12 kw each for for resturant flat bottom tub water heating/teat, milk, etc pl reply
tell me more about your aplication via mojtabashomal@gmail.com
Hello sir which microcontroller u used to generate pwm
Its not microcontroller based pwm ,actulay it was done with a simple pwm chip
@@MOJTABASHOMAL which pwm chip sir
@@MOJTABASHOMAL
Sir please check your mail ID I have sent my project details.
Sg3525 and it doesn't actually matter
@@MOJTABASHOMAL sir I tried to add feedback to sg3525 to control power but didn't work well ,can u share any schematic sir .
سلام
بچه مازندرانی؟
امکانش هست راهنمایی بکنید تا بسازمش؟
ممنون
bhai phn num send kare
I learned nothing thanks.
