Induction - Věda a technologie
Amazing power of resonance: the same place of circuit turns red both thick copper wire requiring dozens of amperes to glow, both thin tungsten wire, requiring dozens of volts to glow.
this is the most simple ZVS oscilator i've ever seen, it works but it seems that the standby curent is high, perhaps you can create another version with lower standby current, it will be awesome
В конце видео один транзистор сгорел. Ток был 2.7 ампер, потом подскочил до 9 ампер. Полевые и IGBT транзисторы имеют ограничения по напряжению на затворах. Не более 20 вольт.
стабилитроны в затворы не ставил и транзюки на радиаторах
Причина горения в том, что провод катушки был намотан слишком тонко и нагрузка находилась на одной стороне.
@@MsAndru79 зачем так, контента не будет. Народу нравится мощщ..гром и молнии)
@@ZAFERYILDIZ52 нет, как раз причина в сгоревшем транзисторе. он сгорел в тот момент когда ток подскочил очень резко! смотри внимательнее
La tensión de puerta del IGBT, no debe superar los 12 Vcc, en el peor de los casos ...
Y encima, puso a trabajar los IGBT SIN RADIADOR, sin el soporte correcto, en alta frecuencia y potencia ...
No podía pasar otra cosa que TERMINAR ROTO ...
Un trabajo de mierda ... 🤦🤦🤦
Спасибо Вам за ваши видео! Очень интересно и приятно смотреть ваши разработки.
Благодарю вас от всего сердца за поддержку и искренний комментарий.
I like this very much. I was going to bu one, but i had the parts to build. Only experimented with it for 2 hours. I tried 0.40uf to 1uf but little change in performance. I parallel IGBT's for use of 4, again little difference. Next i will try different coils but circuit seems tuned well as is. Used 13 volt motorcycle Lithium battery.
Please be safe the current draw is alot. This circuit has no choke too so it will take as much as it can get from the power supply. I suggest you use an old laptop charger or make/ buy a dedicated power supply. The charger only get around 100 watts of power so for more use a big power supply or use a lead acid battery for a car. The power you saw in this video can be done with 100 watts. To melt the metal you will need more power. 1000 watts would be a good start. Just make anothe circuit. This is not reliable and safe!
J'ai essayé le montage, ça fonctionne bien, pas oublier des refroidisseurs sur les transistors, bravo !
Finally I got new knowledge from this video

You do some of the best builds of skeleton circuits on the planet, literally. Well done!! Truly interesting circuit with no diodes, resistors or inductors (other than all the copper). I look forward to your next video!! Thanks!
Many channels will use this design closely :) Thank you for your comments and support.

love to the philippines
I love watching your videos. I was particularly intrigued to see how you would create an induction heater without a coil... until 2:44 when you started to wind a coil!! 😂😂
the aforementioned babon indicator
He meant the choke i guess. Anyway there's a good reason why the intelligent inventor of this circuit uses zeners, resistors and choke.
but i guess safety and sense have also become obsolete in this new era of making video's on proven topics and trying to be a wise guy.
@@ZAFERYILDIZ52 What is a babon?
GREAT VIDEO!!!
On a standard induction heater, the peak output is about three times as much as the input, however, on the IGBT induction heater it is about three times LESS. Is this correct??
THANKS MUCH!!!

VEREY NICE.THANK YOU
bermanfaat banget boz..
Гениально👍☝️
The circuit looks like a transistor based multivibrator. The IGBT needs to be on heat sinks since circuit current is nearly 6.8 Amps. Heating a blade is only for demonstration. If one wants to heat bigger objects the circuit should be scaled up with a good power supply , cooling fan etc. Good work.
Any one no of a good temperature control for that circuit
Would this configuration work with an igbt like a Mitsubishi qm100dy-h igbt (or equivalent)module? 600v 100a would make for quite an inductive heater.
هل تعمل جيدا برأيك
Would this build work to heat a bolt (stuck) that fits inside the coil ? Ive been looking for one of the tools but the costs are too much for me (not a mechanic). I watched another video where they used an old twisty style light bulb and built one.
ماهي اقوى دائرة يمكننا صنعها لصهر المعادن
Nice Video and excellent wire forming skills!
Every time I see people useing "Lead-Free" solder, I feel sorry for them having to use it instead of 60/40 or 63/37 eutectic solders.
How do you know it is lead free?
Because I did not want to say that the solder connections are/look awful, I blamed that on lead free solder instead of soldering skill.
I have been Soldering for over 50 years, and I have used ROHS Solders before, and they are no where near is good as traditional solders still are. You should try it sometime! @@electrocat9
60/40 isn't eutectic. Stick with the 63/37
Eline saglik ustam bir de bunu kaynak makinasi ile yapabilir misin
All that stuff is basically a DC to AC converter that I assume has a pretty high frequency? That frequency would come from the value of the capacitor?

Wow, flux used on a video like this. Congratulations! Would love to know how hot the transistors are running. I know the coil is crazy hot as that is normal and limits the duty cycle of induction heaters if you don't use tubing with cooling liquid.
Merhaba Dhafer kardeşim. Bu yöntem IGBT'yi aşırı ısıtmıyor mu? Çabuk yanıyor mu, yanmıyor mu? Lütfen cevap verin. Teşekkür ederim.

Typically tank circuits will fry the transistors if you slowly bring the power up. [They won't start oscillating] They require instant voltage application to it ???
For a 72 watt heater use for few seconds at a time that will work like that
IGBT without heatsink, how long does it last?
With a heatsink, is this capable of running 24 hours?
PEKİ HOCAM bu ebatlarda isitici max kaç mm kaınlıkları ısıtabilir ? mesela bi 5 mm ısıtabilirmi bıcak yapımında kullanmak için işe yararmı

Title: no mosfet **mosfets**
WHAT THE?! NO NOTHING?!?!!
Daha güçlü indüksiyon için bir bilgi alabilirmiyiz.
Why did the coil start glowing as well?
Nice. Now see how far you get with it in your carry on bag.
Can you modify this circuit to use a flat coil please?
It's not a flat coil, bro, but you can wrap it on a core.
Как понять название , без транзисторов ?
Mosfetli versiyonlardaki gibi şok bobini taksak iki çıkışlı olarak çalışır mı?
Çalışır
Bikin yg bisa di jual di pasaran mas ?
It's possible for testing purposes, but definitely need a heatsink for IGBT .
In a good zvs driver the mosfets don't heat much. This circuit is not good. Since the zvs switches the mosfets at 0volts the mosfet never needs to block a huge voltage and current and will not heat. Also mosfets are better with higher frequencies. This is a nice experiment, but not usable imo.
Is it possible to make induction heater using bjt?
Not really. The zvs circuit counts on one mosfet turning on faster then the other. This is due to the fact they use capacitors on the gate that need to charge. When charged they open the drain. A BJT does not use capacitors so they will turn on simultaneously so there will be no switching and they will stay open and burn.
Nice
Единственное несовпадение, которое я не могу объяснить, это когда осциллоскоп показывает без нагрузки 100 кГц, а под нагрузкой 180 кГц. При этом синусоида расширяется. хотя частота увеличивается.
Частота была 181 без «нагрузки»(повышения индукции) и 160 с дополнительной индукцией
Bravo Hocam 👏
teşekkürler kardeşim
Cool! 😎 🔥
Ellerine sağlık ustam sayende çok şey öğreniyoruz. Bobin yok galiba yanlış bir ifade oldu ustam bir tek bobin var aslında devrede indüksiyon tarafındaki boobin.
başlıga sığmadışok bobini bahsi geçen
Sahi said bro
Saya ingin tau kumparan yang lebih banyak utk menyalakan lampu 220v atau pake kumparan sekunder yang dimasukan ke dalam kumparan primer induksi tanpa ferit
Tes tegangan pake dioda cepat diantara kumparan
👌
would this heat denser metals is the question
Так надо попробовать на МОП-транзисторах. Напряжения тут низкие!
А каково практическое применение?
Usta bunu biraz daha güçlü yapmak istersek voltajı arttirsak yeterli olur mu
daha güçlü IGBT kullanmak daha iyi olacaktır
I don’t understand the lightbulb.
You get current drawn when you have resistance. Like a light bulb for instance. Powering the light bulb would be more useful with the minleaf variable power supply.
Otherwise I was able to follow along to your build on a different take of induction coil heater. 😅
You dont looked how is warms on 14,18,20 V ... please look it
Great.
use 1/4'' copper tubing to make a coil so you can water cool.
Good
thx my friend
А можно рассчитать схему для мощных IGBT-сборок от драйвера сервопривода? С питанием 45-50 вольт? Как это сделать? Если можно подскажите пожалуйста. Я в экспериментах не силён. 😅
Частота 182 кГц не слишком высокая для индукционного нагревателя?
Чем выше частота, тем быстрее нагрев и меньше потребление соответственно из за поверхтностного эффекта. Но защиту управляющего электрода транзистора от перенапряжения я бы предусмотрел как это делают в типовых схемах.
@@zootehnik6662 спасибо за ответ.
Но получается, что деталь, особенно массивная, будет на очень высокой частоте прогреваться только в поверхностном слое?
А дальше ( в глубь) будет греться только за счёт теплопроводности?
@@user-sc5jy8ed6z
Это не такая большая частота, что бы токи были только на поверхности. Для цементации детали это хорошо чем выше частота, она не будет хрупкой. В любом случае это ускорит полное програевание детали так как теплопроводность металов высокая. К примеру то что не нагревается совсем на частоте 10мгц, не выдерживает температуры на 30 мгц при той же мощности из моего опыта
@@zootehnik6662 благодарю. Думал там частоты килогерц 20-30.
Не знал, что мегагерцы даже используют.
Считал, что на таких частотах на излучение будет тратиться энергия.
@@user-sc5jy8ed6z Извините если ввел вас в заблуждение. Я привел пример из области радиотехники для наглядности. Для индукционного нагрева обычно используют токи разных частот - промышленной (50 Гц), повышенной (150 и 250 Гц), средней (от 0,5 до 10 кГц), высокой (67 и 440 кГц), сверхвысокой (1,76 и 5,28 МГц). Ограничение по частотам из за дороговизны и отсутствия электронных силовых приборов на такие мощности. Потому так называемые сверхвысокие частоты используют для относительно небольших по обьему деталей. Более детальную информацию вы найдете погуглив. Успехов...
Сечения провода катушки? Заранее благодарен
На вскидку 2 квадрата где то, может полтора.
40N60UFD is an IGBT or a MOSFET? Looking over datasheet looks like a MOSFET and not an IGBT.

🎉 super
thx my friend
I like bravo
Can you increase the voltage to 36-48VDC to maximize the wattage?
No because you will destroy the gate of your igbt's wich will be rated for 10- 20volts. For that you need the zeners and resistors. Maybe there are igbt's with higher gate voltage but most will have that threshold. Just build a normal zvs driver. This circuit is not usable. A good zvs driver is more efficient than this piece of junk. This is just an experiment to show it is possible, but it's not a good idea imho.
@@davypeleman3672 OK, Thanks! Yeah, I think they're rated at about 20V.
Any idea of the oscillating frequency of a typical ZVS driver? High freq seems to be the key here.
Do you have any suggestions of things I should look for when searching for a good ZVS circuit?
Or am I better off just buying a prebuilt driver for +-1KW?
I want to build a something I can change coil sizes on and power with invertor or batteries.
Thanks
@@onestoptechnologies7305 Search for ZVS driver schematic also known as the flyback driver. Steve Ward or Telaundmehr have a nice webpage where you can find it too. This is the best circuit imho. It uses more components but is very reliable and the mosfets will not heat alot. ZeroVoltageCrossing means the mosfets turn off at 0volts. So they don't have to block the current. And so they don't heat alot. This is what makes this circuit efficient and is not hard on the mosfets. I have build many and some are old. They all still work never blown a mosfet with them. The frequency will depend on your heating coil and capacitor combo. They will form an RC circuit. But the frequency is not critical in this application so you can experiment with that. It should however not be too slow. Keep the capacitor below 1uf and you should be good. The longer the coil the slower the frequency. And use the right capacitor it needs to be a film capacitor. Don't use a polarized cap like an electrolityc that would not be good. It will blow up 😅😅. If you want 1kw you will need a good power supply. at 24v that would mean +- 40 amps. Or use 48 volts at 20 amps. That would be 960 watts to be precize.
مهو بيعوض دا في سحب امبير عالي
How long do you think those IGBTs are going to last with no heat sink?
In a good zvs driver there's not much heat produce on the mosfets since they swith at 0 volts. My zvs could run without, but it is always a good idea to use a heatsink in such power application. Anyway i use small heatsinks and they stay cool. Then you know it's working as it should. This circuit is just not usable, a good experiment to show it can be done, nothing more.
