Help for accessing some data

[boguslaw]

Hello,

I need your help. I'd like to see schematics of actual induction heaters or stoves used in kitchen. I know that it is restricted information available to service stuff, but what I need is to learn how it was constructed to convert AC 230V to high frequency currents.Is there is a common pattern with diode bridge charging capacitor bank and then HF driver and mosfets ?
If somebody could help me please drop me a private message.

Hello,

I need your help. I'd like to see schematics of actual induction heaters or stoves used in kitchen.

Induction hobs are sold by Maplins, John Lewis Aldio and Lidl. Many others. Service engineers need the schematics. You should just to ask.

I just asked. Any service engineers repairing such hobs here ?

The common circuitry? Mostly a motherboard with simular components that plug in.
If your application does not match equivalent parts then modification may be needed.
As you said the manufacturer will use their own house numbers.

In the event you decide to modify then a basic spice circuit will speed the design.
A careful comparison with other schematics may help in choosing which are right for your application.
Finally the parts data sheet can also give you the correct setup parameters.
Most important be very careful because the amperage, voltage and induction hazards, shock
or explosion of parts. The project is only for experienced heavy duty electrical technition.

Thank You.Looking at those schematic I'm now sure it can be easily converted to HF power source ;-) Nice. Just charge capacitor and provide separate power to ICs and microcontroller. Akula or Ruslan could post such video with self-powered induction cooker.

Check out the IRS2453(1)D datasheet.
It does not get much easier. (up to 100 KHz)
