I am amazed by this video... it is really amazing you're still alive while working with high voltage electronics... just a quick recap: - Non-existent soldering skills - Wrong soldering tip - Your sponge is underwater - No thermal paste on your mosfets. - End the video by placing an electric kettle WITH water next to a live circuit. - Wraps stranded wire in plug instead of using a connector (notice those wires are supposed to be carrying 220V). It is a miracle that you're alive. Please, if you're watching this video to learn something, learn that this is not the way to work on electronics, specially if they involve high voltage. DO NOT DO THIS AT HOME!!

Да ! 4,5 киловата - это 500 ампер от 12 вольтового аккумулятора! Через проводки сечением 0,5 мм ? Это - ФАНТАСТИШН!

Я не сильно большой спец в электронике, но трансформатор такого размера имеет мощность максимум 300 Вт, ну и ток 200 А через такие проводки и крокодильчики это фантастика. Также отсутствие броска напряжения в момент отключения и подозрительно длинный провод от чайника заставляют сомневаться в правдивости этого видео.

Особенно понравилась регулировка напряжения и частоты ОДНИМ переменным резистором - по часовой ( V ), против ( Hz ) - главное , что подключено на мультиметре . Ну ,а получение из 300-500 Вт трансформатора 4500 Вт - тянет на Нобелевскую премию - как ни как , а ВЕЧНІЙ ДВИГАТЕЛЬ получили .

No voltage drop with electric kettle? without voltage feedback? something it's stink here...

Я очень сильно плакал , такой простой схема , 4.5кВт мечта , и как мало компонентов , а пайка какая божественная - 200 ампер без проблем выдерживает 😀

It's amazing the 2000w load didnt make the voltage change even a fraction, and you can carrry all those amps from the low side with those small wires, you managed to re-write physics! Nice job

Great! I never would have thought you could run 100+ Amp through those thin DC cables 😂

С учетом масштаба кабель от чайника до вилки больше метра длиной.Чудеса.С такого транса можно вырвать и 10кВт но на частоте не ниже 1,5 кГц.А то что вольтаж не дрогнул-тут уже Нобелевская премия маячит.В общем все херня,переделывай.

The IC is 4047 its a monostable/astable multivibrator which gives out a square wave so its a square wave output and not sine wave.

From where you get the sine wave? Oscolloscope broken?

What kind of battery are you using? The should be a voltage drop with the kettle

Хорошая шутка 👍. Такая энергия и тоненькими проводами. Я думал должна работать физика, а тут колдовство какое-то 😁😁😁.

Да ты не скромничай! Добавь ещё нолик,45кВТ это самое то!с таким трансформатором вполне реально!😆😂

Please repeat and list the name of materials you are using as built the invater

Esse projeto serviria pra um estabilizador? Se sim poderia mostrar como integrar ele a um? Obs estabilizado fabricado tbm não aquele que vem pronto

" Тут главное, как следует, запутать физику. И пока она во всей этой х..не не разобралась, все работает. " Д. Дью

Хотел написать про то, что напряжение при вкл/выкл чайника не изменяется, но зайдя в комментарии понял, что заметил не только я 😁

what's the resistance of the resistors you connected between mosfets?

Inverter yang sangat baik dan sederhana mudah untuk di praktekan ❤❤❤ good job

4500W : 12V = 375A Чайник, допустим, 1000W : 12V = 83A Даже для чайника нужен сварочный кабель сечением хотя бы 10кв.мм.

И главное, когда чайник отключился напруга на приборе даже не дрогнула.

Just out of curiosety can linear voltage regulators be any chance do some thing similar ore internals of a blinker relay???

Bonjour. Quel sont les tensions du transformer ???

Мне подстроичный резистор прикольнул 🤣 чистоту и вольтаж регулировает

Мощность указана в Китайских единицах измерения? Чайник питался явно не от этой схемы, иначе бы крокодил расплавился первым! А так ни просадки питания, ни дым от проводов

Have you use step down transformer and high current to give reverse i.e, 220v to 12 0 12 reverse 12 0 12 to 220 Their current is 20-40amp To give this value of wattage ?

In order for 1 Ampere to come out on the AC side, 10 Amps must be entered from the Dc side.

Когда он запитает сварочный аппарат на токе 250 ампер я может ещё и поверь.но то что он запитал всё это через крокодилы которые от 10 ампер начнут греться.это просто верх ГЕНИАЛЬНОСТИ.

А что так скромно 4.5 Квт? У тебя одним подстроичным резистором и вольтаж и частота меняется? А посадки напряжения нет? Вы фокусник 100лвл! 👏👏👏😆😆😆

Is the signal changing polarity? Because I don't understand how with same polarity on signal wires the system can work. I mean if one wire gives + and it's attached to one side of mosfets and the mosfets turn on while the other signal wire(-) doesn't turn on mosfets. The signal has to reverse it's polarity for the system to repeat on the other side of mosfet group.

Sería bueno ver la forma de onda en un osciloscopio. It would be nice to see the waveform on an oscilloscope.

Nice concept, but in reality there's NO way that output transformer is even CLOSE to a 4.5KW transformer, definitely not continuously over long periods of time. That is only about a 500-1000W transformer if used continuously, otherwise it would get too hot. I've seen the insides of quite a few pre-made and branded inverters of around the 5000W size over the decades, and their output transformers are always MUCH bigger than this one is, (at least at this relatively low frequency switching level), plus I actually have a few surplus transformers of almost that exact size physically, and NONE of them can put out anything over 1200 watts continuously without overheating, I've tried... Not to mention, your supply wires on the input of this are WAY too small to handle the current needed from the lower voltage input source in order to actually power a coffee maker or kettle or whatever that is there, because you can't get more power out of something like this than what you put into it, it's just pure basic physics that apply here, so if that water boiler/kettle or coffee pot or whatever is even a relatively small wattage one, it's still gotta be about 1500-1600 watts or so at least, (most likely even more like 1800-2000 watts), and therefore there is absolutely NO way that those tiny wires you're using on your input to this inverter circuit wouldn't just completely melt or even light on fire from the current going through them IF this inverter WAS actually powering that coffee pot/kettle/etc., so I call total B.S. here and say that this video is fake and simply rather misleading clickbait, because the title of it makes people think that this exact setup will be able to put out the amount of power that's claimed, but there's NO way it actually could in this configuration!... About the ONLY thing that this inverter actually could be powering here is that lightbulb, otherwise if any more than that then the tiny supply wires would just burn immediately, lol! Also, this is NOT a "sine wave" inverter, it's more like a square wave inverter, because of that IC that chops up the input voltage, but at least the output transformer gives SOME "smoothing" to the output waveform, simply because it's a purely "analog" device and doesn't respond immediately to the rise and fall of the square wave coming out of the mosfets... Let's maybe call this inverter a "modified sine wave" type... or more accurately a "modified square wave"... This IS a cool concept video though, of the very basic wiring of an inverter circuit, which is cool to see at least... but that is all this is really good for... to show a concept of how a basic principle (of an inverter circuit) works. Where did you get that pre-made circuit board with the IC on it? (I know the actual PCB is made from that website sponsoring this video, but I mean where was it's actual circuit design gotten from? Is it like an "inverter kit" that you can buy somewhere or something?)

Нет здесь никакой синусоиды, обычная push-pull схема бюджетных ИБП с аппроксимированной синусоидой, габаритная мощность трансформатора максимум 400 Вт.

Сколько чайников ремонтировал и не разу не видел такого с шнуром в полтора метра, один раз преобразователь чинил тоже что то около 4 квт , так там вводные провода как на сварке были, а тут китайские в три волосинки. Прям чудеса премию давать можно.

What is the input voltage

Почитал коменты .Улыбнуло;)))). Килловаты,амперы, и синус во внимание можно не брать, но вскипятить за 3секунды воду в чайнике это жесть.

2000 watt czajnik, zasilany przez przetwornicę na wejściu nawet gdy by było 24V to przy 2000wattach to ponad 83 ampery. Te "nici" co są podłączone na wejściu przetwornicy by nawet nie zdążyły "pierdnąć" i było by po nich.

Whats the maximum frequency that it can provide ?

Boa noite quais os resistores usado no projeto esses dos Mosfet resistores igual ou tem algum diferente

А где обещанный синус? То что частота 60 Гц не говорит о форме сигнала. Без обратной связи при подключении 2х киловатт ного чайника напряжение не шелохнулось, магия?🤔 Подключение вилки вообще шедеврально😁

Whith the used wires and transformer, it is not posible to pass more than 20 real continous amps. 12V x 20A = 240 Watts. Asuming a 80% efficiency (as a good favour) you get a maximum of 200W of real power at the output (and forget the senoidal feature, of course)

Oscilloscope and circuit diagram should be provided bro

Excelente! Tenés el análisis espectral?

С чайником насмешил просто . ! 1,8 кВт (как минимум) и по слаботочным проводам , и без просадки напряжения ?! Фантастика !

Чтоб выглядело правдоподобнее нужно чем-то просаживать напряжение и подбрасывать когда включается и выключается чайник.

Hola, el diagrama del circuito no lo puedo encontrar en el blog , gracias.

J'aurais une question un peu bête mais je pensais qu'un onduleur devait disposer une batterie pour stocker l'énergie. Du coup, comment fonctionne le circuit ?

Nice , good But it is not sinewave inverter Not 4500 watts Ur using 4047 ic , it is square wave osolator.

You use 8 IRFP260N transistors, they are 300W cad, in total it has 2400W, they are missing 2100W, and the 1mm 12V power cables would melt completely with a 2200W consumption that at 12V they are 183Amp, I am not saying that your inverter it does not work, only that it must be more realistic with the power, otherwise this makes it look ridiculous in front of people with some knowledge in electronics

What supplies are you using?

Very interesting video and so recommended to be shown are size of that very small heatsink and its temperature to be raised up, and also the sizes of core, coil and the diameter or wire, needed to get such big power as 4500w through more 400A from 12V source, and also needed more than 16 or 32 MOSFETs-260N(200V,50A) for switching here, thanks.

Красота!👏

What are the resistor value please I want to know

Can you tell me what gauge wire you were using

Трансформатор великоват, можно было поменьше поставить.

Where is your sine wave? Where is the 4Kw load? The transformer is small for 4Kw, I wonder if you can get more than 1Kw.

How do you keep the transistors cool without heatsink grease or did I miss that being applied?

I think that if the kettle is a resistance element it will work on DC as well as on AC.

When using mylar insulators thermal paste should be used. Or so i thought.

When soldering, heat the joint and then put the solder on the joint… not so much the iron. You’ll struggle less with making the joint this way, as you don’t rely on solder flowing from the iron… but instead it flows directly onto the workpiece instead. Yes you need to put some solder on the iron to create an efficient heat bridge, but once you get that going, it’s better to put the solder on the joint as opposed to primarily the iron.

hi, can I use there 12-0-12 volt 10 ah copper transformer for take 800 watt load?

Con esto te formaría una senoidal modificada, tipo cuadrada?

You could have used the scope on that meter so we could see the sine wave! Plus it would have showed both the voltage and HZ on that setting. P.S. like this video

Nice work, thanks to sharing it with us. Can you please use an oscilloscope to display the wave form?

And the micrometer on the 300VA transformer is to?

Hello, please reply, can you give the value of the resistors you used? Thank you very much

Never make a solder connection without making a good mechanical connection first. Those joints may look nice but are prone to failure.

This was very impressive sir. Some good projects on your channel too. Perhaps a few in video text prompts to guide those of us with poor eyesight regarding resistor values etc. But that takes nothing away from the content. There are some good applications for the builds you have shown us in your videos, they are practical and helpful. Thank you for your hard work sir. You have a new Subscriber. Liked as well.

Для 4500вт какой трансформатор нужен?Кг 30 хватит???и чем его запитать,чтоб снять 4500вт?

What value of the source voltage?

I think that the tranformer size is very very small(300VA?).The Inverter could not output 4.5kW.

Nice job. Just one suggestion. You should have put a bit of heat sink compound on both sides of the mica strips under the Mosfets.

You connected in battery or AC current

selam hicbir soruya cevap yazmamissiniz zaferbey nerdeyse tum videolarnizi izledim ve bir kac projenizi sayenizde yaptim ve caliyor lakin bu direnc olayina biraz yabanciyim taktiginiz direncler hepsi ayni degerdemi ve degerleri nedir onu aciklaya bilirseniz sevinirim

There is no way that wiring will handle 4k5w. At 12v that's 375amps.

When soldering the components, an order by height must be established. First, solder the components closest to the board first. solder 2 pins against each other and check that they are tight before soldering the rest of the pins. and lastly the highest components...

Does anyone know how many resistors are?

A nie prościej byłoby wrzuć link do całego zestawu wszystkich potrzebnych części aby zronić taki falownik?

надо отправить о ложности информации, чтобы ЮТУБ не мусорили

Components are handled with pincers which is very practical, since the components are temperature sensitive

when i goto your site to see inverter parts for this theres no way to download can u direct me to full diagram of parts thanks lee

What kind of waveform is the output?

Saludos, independientemente de la potencia que manejen los mosfets, el transformador no tiene capacidad para dar, no soportar 4500 watts.

Tengo una duda, como es posible controlar Voltaje de salida y frecuencia con un solo potenciometro???

12V to 72V 5000W Continuous Output. Can you share the boost circuit?

Hiç bir yerde bulamadığım bir soru sormak istesem modifiye sinüs invertor deki çıkış 220 değilde 190 gibi volt neden oluşur yük de veya yüksüz durumlarda neden kaynaklanır teşekkürler şimdiden.

Would be great on my boat, although I'd use a 555 timer and solder it onto a Veroboard. At a full load of 4500w each MOSFET would draw a whooping 375/8 ~46 A. A 1kw inverter would be ample for many applications.

5:53 - не понял что включилось... Я как бы все звуки электричества за 20 лет знаю. Трансформатор так не щёлкает и лампа тоже...

HOW IS THE CONSUM OF TRANS FORMER DIRECT LINE

Nice work. You must showing sinus wave form measuring with oscilloscope.

4500w de unde?Poate pentru 0,00001 secunde.

Taaak. Na pewno jest 4,5kW i sinus na wyjściu. Jest taki sinus jak kwadratowy jest łeb Spejsona. 😁

Posso farti una domanda .si possono usare i transistor tip 136c aspetto risposta.grazie.

Ależ to wszystko proste! ;-) Jaki jest największy problem przy tworzeniu perpetuum mobile? Ukrycie źródła zasilania! ;-)

Hola buen video podrias compartir tu diagrama osea de la plaquita para poder hacer yo uno tambien

О как ? Одним подстроичным резистором регулировать напряжение а потом и частоту?

modified or pure sine wave?

Where can i find the transformer? and can i use 10-0-10 transformer?
