I'm a service repairman for GE Appliances in The United States. I replace these board from time to time. Most of the time the visible failures for these boards are the capacitors. Our induction coils has a glass wool sheet insulation covering them.

This is fantastic, i have been considering buying a broken induction cooker for a while, just to see how it works, so this video and the next one, couldn't be timed better :)

Thank you Diode! Another video, great production lately!

I've seen guts of / repaired several induction hobs from european brands; AEG, Electrolux, Bosch, Whirlpool .. and really, I could swear blind there is only one factory designing and producing these here in europe. This unit our artist has got hold of makes no exception :) And hey @DiodeGoneWild , thanks for the informative video - again. NOT dodgy stuff indeed ;)

Thank you Dan. A fantastic set of videos. Fixed my NEFF HobT36FB41X0G (virtually the same as your hob but with additional relay switching).Testing with two temperature sensors swapped seemed to generate a recalibration and removed the fault.

Excellent knowledge and patiently exploring the circuit.

I have not seen the data of this but normally they are around 7.5 KW with all the coils on at maximum, but I have also seen 9 KW! It should be added that it is difficult to use all four inductors at full power, because normally it goes to about half, apart from when you have to boil the water for pasta (here in Italy the main food in a meal) where you start full power to a boil and then drop to half to keep it boiling so a salesman told me, hope he wasn't lying in hopes of selling

You're correct, that extra relay around 14:00 temporarily provides a power boost to a coil for boiling water seriously quickly. It automatically cuts out after a few minutes. I have the exact same power boards in my Bosch; I had to replace them after a big voltage surge on the grid. The power company paid, but took the old boards as proof. I kept the massive heat sinks thoigh

Great explanation of the boards. In part 2, could you explain how it puts the correct amount of power into steel/iron pots of different types - otherwise you would never get consistent results from your pot collection :o) Also I believe these can detect pot/no pot so you don't destroy your wristwatch near it when there is no pot and a heater is on. Thanks DGW.

If you are not using those boards you can always salvage components from it. If I had even one of those boards I will not leave a single resistor on it :P

Although I like your videos good work

The microcontrollers are probably all types of protections (overvoltage, etc) and of course for controlling the diaplays on the other board.... and probably even for the temperature protection NTCs. imagine designers, how do they actually be able to design this stuff... they have probably a huge experience... which i hope to have because i love electronics!! P.S - broken induction cooker boards are very useful because you can desolder all this components that can be useful (Full bridge, relays, IGBTs, toroids, film capacitors and other stuff)...

Awesome! Now I know why I hear very loud 100 Hz humming whenever my phone buddy with wired handsfree approaches turned on induction stove. I almost thought 100 Hz is the operating frequency of the cooker but that sounded odd. Lack of smoothing is much more plausible explanation. I don't understand the purpose of bonding the half-bridges together. I would expect they would reconfigure to full bridge, but it is not the case. So basically it just connects the IGBTs in paralel. Is it only to lower that (already pretty low) impedance of turned-on IBGT?

I tried to fix one of those last year. And I came to the same conclusion that the cat did. It's way too complicated for the purpose. The bridge rectifier and IGBTs failed shorted on the big induction side. I had a hard time finding thin ceramic insulator sheet to replace the one I mistakenly thought was silicone compound. I broke the ceramic while removing the spring clamped heat sink. The output board works now but the control board has weird intermittant isssues.

No I think it is a temperature sensor. It is measuring the HF current to sense if a pot is present, so the coil itself is the sensor. These induction stoves often have a temperature controlled mode in addition to the constant power modes. Plus they can sense if the coil is overheating with it, which can happen if someone leaves an empty pan on it or similar. It will heat up to hundreds of degrees which eventually gets through the glass and insulation to the coil.

Induction cookers are much more pleasant to use if many power levels (probably determined by duty cycle) are possible. My one-burner cooker has nearly 100 power levels, and that’s unusual. Cheap ones can have as few as 8 levels and unless you’re just boiling water that is annoying. So some complexity could be providing more power levels to the user?
