One of the best electronics videos ever. You are a brilliant engineer. Everything you figured out makes complete sense and is very understandable. I love your videos. I have increased my Patreon from $2 to $5. You present the technical details and your cat the practical interpretation. Keep up the great work!

The power button usually needs a long press, to make sure you dont activate it too easily when cleaning the glass.

Nice! Thank you. The capacitive buttons probably need the glass plate in between them and your finger to function properly.

You have a real gift for explanation. I hope you are using it in your working life

I always amazed with fine tuned resonance circuit. for me it's like a black magic, but again to put it simply it's like pushing a child in swing when the swing at its peak so the oscillation is not interrupted, BUT implementing this on an electronic device it's still amazing and bloody complex.

I like your bloody long video’s!😉

I have never seen such in deph circuit analysis on KZfaq. I absolutley LOVE your channel.

some pots have a iron core attached under them so they can work with any induction cooker

My friend, your videos are never too long! Thanks for your contribution. I look forward to the next video.

You have to be one of the best on KZfaq at explaining the schematics and how a circuit is doing whats its doing. i know im not the only one to think/(know) this!! BLOODY BRILLIANT VIDEO! : )

Excellent video! Your explanations are better than I've ever gotten from any book!

much awaited. niceee

Very interesting. I have the same cooker in my house and now I know how it works.

Totally mesmerizing even though I'm in here watching well above my head. I thought I'd look for a minute or two to at least know what it was and then decide and BOOM the video was over haha!

Thanks for fabulous tremendous work!

Fantastic video(s) DGW ,,Thanks for sharing. ,,Definitely worth Patreon support.

awesome complexity for a heater, thanks for the vidoe!

This content taught me more about inductive circuit and zvs in 20 minutes than any other.Thanks so much for your straight forward explanations.You are as effecient as this zvs circuit! Question... I would have thought the freq at the halfbridge would be 25 hertz or there abouts as 50 hertz is coming from the outlet?I suppose that is the freq from the transistor going into the coil but what happens to the mains outlets freq as you said they overlay each other. I would have thought it would get ugly on the scope when they clash. What is driving the gate ? Kind regards Andy

Very good video i have an induction board with problems this video came to help understand how it works.

Thanks for the interesting video, I learned something new ;)

This reminds me of Dual Resonant SSTCs, I wish you could build one someday

Very good explanation. Thanks

The 7KW is why us brits have a dedicated circuit for such cooking appliances, terminating in a hard-wired cooker connection point usually, no need for any two or three phase power... :)

The most powerful one goes to 11. The cooker downstairs can boil a pot of water upstairs.

Have you considered making a series of videos for beginners? I would totally love to see one. Like you show some electronic components and explain how they work.

I remember when I was confronted with this technology for the first time I tried so many different materials just out of curiosity. Those enameled pots work great on induction but I reckon a cast iron one would work even better, perhaps too well.

I love induction cooking, I would never go back to gas or those dreadful infrared things.

This channel is awesome

hey you need to put glass on control pcb to work properly some other induction cookers dont even turn on or show some error if no glass top are attached

Best on youtube.

straight chromium grades of stainless work (400 series) it is magnetic enough to run successfully. That's the only thing i hate about my induction hot plate. It really is fast and efficient even though i only have a baby one powered off 120v. Glad you finally did a video on induction cookers.

Nice Video. Thanks!

I really needed this Bl000dy h3ll!

Thanks for the insight. I had hoped to run a single ring in a camper/RV and wondered if I could use a square wave or modified Sine inverter for maximum conversion efficiency (and low cost) but it looks like shape of the the rectified Sine input voltage waveform is essential for the operation of the circuit.

Is it possible to use an induction heater as a basis for building SSTC?

Great video! Didn’t think of the power factor problem, i just thought they don’t filter the rectified AC because of cost.

I always wanted to see what was inside. I have single burner one for testing. It works great.

thanks for explaining how it works in great detail. Some isolating sleeve over the scope bnc next time?

Complicated circuits, but they have to be.. Very good analysis!

i agree with your cat :D you give perfect explanation as always

Nice video

Very informative video. I have a question, Why the coils have a gap at its half radius?

I am fascinated by the accent, I have no clue what is going on but I am listening to the accent

thadits nyyyyceee

I hate these capacitive touch buttons! I switches my old microwave with one that have these, it seems that they are designed in a way that short touches on the buttons won't activate them, probably for security reasons, with a strong filtering so that noise does not trigger them at random. The delay in them in horrible, almost half a second, if I want to put 20 minutes I could do 2 quick presses on +10 on my old one, in this new, which does not have this nor numbers, I have to hold the up arrow that starts with 10 seconds delta, then 30, then 1 minute as it gets faster and, obviously, I always end up setting up more time than I wanted, so I have to press the down arrow.... "progress"

Nyce video but if a flyback transformer is connected to it, will it be able to make high voltage?

Where do you put the probe ? Across the capacitor tank or where? To observe the sine resonant.?

3am in the morning...oh quick.. the diodes have gone wild LOL

What happens if you put a tesla coil-like secondary on top of one of those coils? Would it work, or would it refuse to 'cook'?

Well, I once worked with resonance circuits and induction heating. Now I'm working with control algorithms for electric drives and all this resonance stuff is so much easier compared to what I'm doing now. It might sound hard at beginning but once you understand techniques and topologies of induction heaters it'd become easy. When it comes to drives I have a feeling that I might be never able to fully understand all of them. Meh, maybe I should go back to good old resonant circuits?

Niiiiiiicee!

Perfect beauty!.

Ah the sound! That must be a siemens one

Can someone know how the control panel Touch buttons are working and which type of material is used?

Bloody hell, this time I agree with the cat!

Can you try to make a housing for it?

A propos your cat, I also prefer the simplicity of resistive elements. Is inductive more efficient due to lower thermal losses?

Is your cable spliced,or just the outer insulation is damaged and wrapped in tape?

17:24 pointing at screen with metal things makes me so uncomfortable

Your videos are nice. Which oscilloscope model? I am thinking about my birthday present, and wanna some portable one

How the pots are detected by these cooker and why aluminum pot not suitable?

How many millihenries is the coil?

Brilliant video , I’m repairing an induction cooker now so this couldn’t have been better timed . I am surprised to learn that you don’t understand how induction cooking works - your pots must be magnetic in order for the induction to heat the metal. More modern pans come fitted with an iron plate at the bottom to make them compatible even though the rest of the pot might be made from aluminium .

Is it possible to decrease the minimum temperature of any induction cooktop? Let's say, mine says 140°F but it boils water, I want it to be cooler.

Oh, Ohm on my Range... Where the waveforms don't seem all that strange... Never was heard, a discouraging word... _(everybody sing or hum along now @ 50/60 Hz....)_

I suggest Allegro ACS733 current-sensing chip.

Wow,this cooker sound like a Geiger-Muller counter.

I'm waiting when you conect this to flyback or tesla coil

Nice video , can this cocker wirelessly charge your phone or blow it , You can use one of the big winding to make a wireless charging table .

It look odd how the power is redirected at 9 level for single cooker, because that means you cannot run them both at full power. Induction cooker I have and others I seen all have boost mode, there essentially total power from both cookers are redirected to one.

The benefit of an induction cooker is that it heats the food, not the whole kitchen! I think when my gas cooker packs up, or if the price of gas becomes too the next one will be an induction one. It takes 4180J. of energy to make 1kg. (= 1 litre) of water get 1 degree hotter, which is just under 70 Watts-minutes. So at 3.5kW, in two minutes it could bring 1 litre of water from freezing to boiling. In practice, it probably will take a bit longer, because the pan is also absorbing some of the heat; but even so, the specific heat capacity of metals is lower than water. And this is still more efficient than using either resistive heating (which requires heating a larger mass) or fire (which loses some heat in the exhaust products carried on the updraught). The reason why water has such a high specific heat capacity is because of hydrogen bonds. When hydrogen and oxygen are in a covalent bond together, the oxygen atom tends to hog all the electrons to itself. This means there is a weak negative charge near the oxygen and a weak positive charge near the hydrogen, so each water molecule will attract its neighbours towards itself a little bit. This hydrogen bond is not as strong as a proper ionic bond, let alone a covalent bond, but it does still take some energy to separate it. Maybe you could make a home-made slow cooker by filling a big pot made of ceramic or some sort of plastic that will not get too soft when it gets hot with stew, and putting some tungsten lamps right inside it so the heat from the lamp will go exactly where it is needed? Another crazy idea: Use solar panels during the day while you are out at work to produce electricity, and use this to sepaate water into hydrogen and oxygen. Then at night, use a hydrogen-fuelled cooker to cook your supper!

Did you try to make a Tesla secondary coil for this :-)

Do cooking tutorial. How to cook parówki or something easy like it.

Please make an induction heater for melting small pieces of metal ;)

5:40 Oh my God! This is a lot worse than my habit of drinking coffee next to my laptop.

Link to the manual: media3.neff-international.com/Documents/9001590144_D.pdf

So, can you reassemble this under ceramic then? Black glass is so boring and ugly.

So is it really more efficient then resistance heater? Or microwave? Let's say we want to cook 1L of water? Also which will be the fastest?

Can this circuit power a Tesla coil?

9 power levels, or is it more like 20 with half-levels? I have used induction cookers with 10 power levels and they are miserable to use unless for simply boiling water. The one I am using now has about 100 power levels, but is no longer manufactured. Its replacement has I think 54 power levels and that is probably enough not to annoy a serious cook like me. I think that power levels are implemented using different duty cycles. I’m in the USA and so it was 120 volts and 15 amps to work with, so at most 1800 watts.

are you having a secret formula to convert watt to amp

turn on the subtitles please

i didnt know that there are actually 4 bridges ._. also, ir21531 sstc when?

Still waiting for the schematic of the 12V 50A 600W power supply 😂

soup tonight then

postawił bym wszystko pod wanną ;}

From cave men who could start a fire with a stick to electric fire that requres phd to start.

Calcurator: historie, tiles: czechoslovakia. Are you from czech republic?

YOU NEED AN ISOLATION TRANSFORMER BADLY. MAYBE MAKE ONE AND MAKE A VIDEO OF IT FOR US.. DO YOU HAVE A 2 CHANNEL SCOPE?? P.S. BEFORE I FORGET.. IS THE RINGS OF THE COOKER DETECTING A MAGNETIC CHANGE AND THAT'S WHY IT WOULD ONLY LET THE IRON POT WORK???

mod it to run at 12v :D

To measure with the 2 Channel scope, you can make a very dodgy thing, which is bypassing the ground pin of the socket. The downside is that all the exposed parts of the scope Will be live :)

Oh, I am sorry to hear your two channel oscilloscope has been misbehaving so badly you grounded it. When is it allowed out again?

A 2 burner resistive cooktop cost $32. A 2 burner induction cooktop cost $230. The induction cooker is efficient but full of circuits that can break. The resistive cooker has no components and will likely last 30years. These things are not energy saving or environmental when manufacture cost are counted.

*Consuming lots of Power, that's scary 🙄🙄*

Someone buy this guy a proper scope.

Quite dodgy Lol 2 funny

Another Robo voice canidate

I liked it until it did not work with most pots. For me that's just unacceptable for a cook top. Heating elements should just make heat regardless of what they're heating.

All that overcomplicated electronics, just to fry an egg. Ridiculous!

and where is my favorite Soviet oscilloscope...? 🙄
