Thank You for this simply thing.
I have a U and I regulated power supply with an outside mounted 2N3055 on a cool rips..with lowest Output Voltage (=max Voltage at the transitor) and max. Out current, after few minutes ..hot cool rips...and they are three times larger than this shown in this clip.
Hello Frank take Darlington MJ 11016 ISC, to find at Reichelt Germany, is 30A 120V heavy duty, but alucooler as big as possible 73s!
Trying to draw 15 amps will destroy the pot. Trying to produce any voltage much less than the supply voltage, at anything approaching 15 amps will destroy the transistor. It's been a long time since I saw someone misuse a transistor/heat sink like this one. For heaven's sake, mount the transistor the way it's intended.
I agree.....but, to be fair, i think he only did it this way so that viewers could see what he was connecting to what here.
@@englishrupe01 No, this guy constantly posts circuits like this. They are grossly overhyped, and are guaranteed to Let The Magic Smoke Out if used anywhere near the limits suggested in the title.
I agree, complete rubbish nonsense from YILDIZ as usual.
Zafer showed the potentiometer value as 220k. That's much too much - the pot should be less , maybe 10k or 2k. Also the center lead of the pot should be connected to the power transistor's base with a 470 ohm resistor. The tan wire will allow the high current to go through the pot when it is turned to the end, damaging the pot and burning out the base of the transistor. Thanks for the video.
RIGHT
Fanstastic work 👏👌 thanks my friend👍👍👍👍
Maximum 4A possible, MJ2955 is pnp and has low Beta, 2N3055 is npn and it’s Beta is better, but for 5A you take better darlington TIP120 npn or TIP 125 pnp with Beta abt 1000, for 10A take 2 in parallel with 2 emitter resistors 0R1, bases and collectors each wired together, collectors in, emitters wired out, bases control, poti only 50 mA max current
The best solution is the Darlington MJ 11016 ISC with 30A current max and 120V E/C (!) to be found at Reichelt Germany abt € 4.00
Лайк заслуженный за проделанную работу и подробный обзор.
The voltage okay but for the amps you never do the demonstration which goes up to 15 amps from the outputs
Excelente, profesor me gusta el proyecto.
Adding another 10ohm/5W resistor is great?
That upside down mounted 2N3055 will not make a good thermal contact with the Heatsink. So there is no way it is going to give you 15AMP.
It's hot glued to the heatsink.....
🤦.
It'll give you 15A, but maybe not indefinitely.
Just an experiment for viewing ...
If you want to try yourself at home at your own risk, use thermal grease instead ! use tight screwdrivers
Put a 15 Amp load and see how long....😅😅.....long enuf to see it quit.
@@jamess1787 absolutely true. You never as a rule mount a to3 package by its top cover. Thermally a 2mm plate has been given for heat dissipation. Novel idea but totally against physical principles
no
Hocam peki bu transistörün base akimi yüksek olduğundan bu pot bozulmasın araya bir transistör koyup aynı zamanda amper ayarı yapılabilir mi yoksa o zaman illa lm317de mi kullanmak gerekiyor.
Zafer esta muy bueno y practico el circuito, puedo probarlo con una carga de 55 vatios a la salida con 12 voltios.
Exelent zafer greetings from Venezuela 🇻🇪.
Zafer bey emeğinize sağlık
Bu tip devrelerin şemalarını ve devre tasarlarken yaptığınız hesaplamaları paylaşsanız daha iyi olur
hocam böyle devrelerin pek etkisi olmuyor aslında yai o yaptıgı devreyle 15 amper cektiremez çünki ne bobin var ne trafo var aslında trafolu bi güç kaynağı devresi yapsa keşke bilgilendirse bizi
Satnasovari bhanotri vaetch nice vedio sir
MUCHAS GRACIAS !!!
Muito top!
Muito útil com componentes fácil de encontrar!
Desculpa minha burrice, mas eu não tô entendendo nada o que ele tá fazendo você poderia me explicar? Se puder eu agradeço.
@@alisonavila7651 regulador de tensão de 1-60v dc 15a
Una cosa que se pueda regular el voltaje pero con carga como se comporta se mantiene el voltaje con carga
I would like to see the verification that if it delivers the current of 15 Amps. The measurement of the 15 Amp.
If you say from 0 to 15A, please how do you adjust the amps?
elinize sağlık hocam
para mi es medio peligroso utilizar la carcaza del transistor... pero si se banca 15 A.... adelante nomas. saludos desde arg
gracias por compartir , puedo usar el 2n3055 para esta fuente? gracias de antemano.
will this work when I set an 3.3V and I want to get 10A from that voltage control? there will be almost 56V drop on transistor under 10A current. not too comfortable workspace for a transistor
El transistor tiene que estar al revés, así no puede disipar la temperatura y se va a poner en corto .
Super!
bien bien hermano ,una pregunta cuanta corriente puede darnos ese transistor
عاشت ايدك استاذ عمل راقي
buenas mi hermano como estas,en ese circuito cuanto es él máximo de voltaje que se le puede aplicar
very good🤩🖐🤘👌👌
Zafer Bey, bu güç kaynağının nasıl örneğin 40V verdiğini bana gösterin ve lütfen 10A ile yükleyin. Bakalım transistöre ne olacak
The total power disipation can be calculated by substracting V input minus V output times the sinking amperes. It is hard to find a power transistor that withstands such parameters.
friend is this source that you are producing for DC or AC?
Não especificou o Power para alimentação, se é 12Vcc, 18Vcc ou 24Vcc?
The thermal efifiency can be improved by drilling a one inch hole in the heatsink, if there is a need to leave it like this.
hi zafer What is the voltage you put on it? and ampers
So nice
Hocam soğutucunun altından üste doğru bağlayaydınız işte birbirimizi germeye ne gerek var:)
👍👍👍👍👍
🤣
hello thank you very much . reza
Pnp tip istenilen transistor olurmu ?
Good 👍👍👍 friends 😊
Parabéns pelo projeto
👍👍👍 Muito bom !!! Posso fazer com INPUT de 12v ou 18v ou 24v DC ???
Yes
@@murat-tj5hl Obrigado 👍
Przy dużym (około 5A i więcej) prądzie obciążenia, jest niemal pewne, że potencjometr ulegnie zniszczeniu w jednej ze skrajnych pozycji, gdyż przepłynie przez niego zbyt duży prąd bazy tranzystora mocy. Potrzeba użyć potencjometru o mocy 0,5 W lub więcej, albo zastosować układ Darlingtona z pierwszym tranzystorem mniejszej mocy, a tym samym mniejszym prądem bazy.// With a high load current (about 5A and more), it is almost certain that the potentiometer will be destroyed in one of the extreme positions because too much base current of the power transistor will flow through it. It is necessary to use a potentiometer with a power of 0.5 W or more, or use a Darlington circuit with the first transistor of lower power, and therefore lower base current.
Hey guide !
I do not think that your circuit can generate out put 15A , I do not believe , voltage is ok , but for the current can not ,,,
That's what I thought!
كم فولتية وامبيرية مصدر التيار الداخل ... نرجوا التوضيح
Very best sir,
Thanks My Frend
làm mạch nguồn 12v được không
Hocam bir sorum var ben de +30 0 -30 bir transformatör var ben 5N4008 ile tam dalga doğrultuyorum 2200 nf 50 volt kondansatör ile çıkış alıyorum çıkışta +40 0 -40 ölçüyorum ve ben maks. +25 0 -25 volta ihtiyacım var ama en az 7 amper bana bi çözüm yolu göster
Iyi kardesim 👍👍👍👍👍👍👍👍👍👍
How many amper you have?
corriente alterna?
I think your transistor is case grounded, if so isn’t the heat sink carrying voltage? Unless you intentionally use hot glue as insulator. Just curious. ✌️
How much voltage input
I made this but not working
You are smart electronics, Mister. But don't show to young enthusiasts which watching you videos this things: it's bad idea to mount elements at radiator using hot glue. And silicon structure of transistor is mounted at thick part of chassis for better cooling so it's impossible to work your regulator with 15A current with transistor mounted "head" to heatsink...
Yes
How to test current?
Can it really take a load 15 amperes?
giriş voltajı kaç v onuda yazsaydınız hocam
Wie wird die Basis geschützt bei voll aufgedrehten Potentiometer, Basiswiderstand Null?????!!!
Nice
Zafer bey pcb si olan devrelerden satın almak isteriz
What's the input?
Valeu pelo didático, mas cola quente no dissipador não rola 😅
Hi,how to add voltmeter ammeter display in this project😁
Sir wuld that circuet work for controling alternator voltage regulator?
The thing is I like to use plasma ignition😅 on my ignition coil ordinary ceramic 3kw capacitors in series on + coil side and simply ground other side .
The effect on my delco 12si alternator is that the cutt in current or some peopel call it starting charge rpm get swaped around .
So my alternator is constantly back feading true the dash bulb on normal idel engine speed so I must increase the engine rpm to shut the bulb off at around 3000-4000rpm my alternator charges normali.
So any one has idea how I can counter that effect???
I suspect my alternator voltage regulator is also ground voltage controled .
So honestly I dono how to fix this problem some peopel sugested resistor/capacitor box some say cloosed loop voltage regulator some phase shifting Im realy confused what to do Im cinde of desperate 😅
On alimente a combien de volt
buenas noches buen proyecto me puededecir el voltaje de entrada por favor gracias
Por lo que muestra el video son 60v.
Why out the TO3 transistor in on the WRONG side of the Heatsink. The bloody thing is already drilled out!
Npn bir transtörün basitce nasıl çalıştığını uygulamalı gösteren temel bir devre
Sürekli olarak yükte kullanmak için devreye potans dan sonra bc ve bd tipi transtör regüle için zener diyot gibi elemanlara ihtiyaç var tabiki
Porque no lo colocas correctamente en el disipador de calor,,esto no es lo correcto en la instalación de un transistor
Top 😍👏👏
Thanks
@@ZAFERYILDIZ52 friend is this source that you are producing for DC or AC?
Bu devreyi 220 ile mi calişiyor
There is no way on God's great earth that transistor can deliver 15Amps.
I once used hot glue to fix my car's muffler and radiator, works like a charm.
Yes 15a is to much
15A is the spec of transistor if he keeps the case temperature @25 C. He does not consider the dissipation of the transistor, Pd=Vce x Ie
Di quanto deve essere la tensione di ingresso
Abi ayarli kör yük yaparmısın
all semiconductors are governed by their dissipation power the 2n3055 is 115 watts and not by their maximum voltage and current tolerances 60v x 15 amp is 900 watts 8 times more than the 2n3055 supports.
ลองต่อดูแล้ววัดไฟด้วยมิเตอร์ดิจิตอล มีไฟมา แต่ลองต่อโหลดหลอดไฟ ไม่มีไฟฟ้าออกมาเลย

The Load change Ouput Voltage..
1-60 V girişi C yerine E ye bağlayıp, çıkışı ise E yerine C'den alırsak durum nasıl olur acaba?
Olmaz npn transistorde kollektor den giriş olmaz sen de biliyorsun bunu pnp olur ancak devre yeni bir dizayn gerekir beyz eksiden sürmek gerekir .
Önceki cevabı yazdım amma burada bir kontrol giriş değişikliği uygulanmış saskinim
Yani dolayısıyla c yerine e ye baglarsan polariteyi değiştirmen gerekir
@@murat-tj5hl ben 4 meslek (makina motor / elektronik/ yazılım programla/havacılık simulasyon) sahibi biri olarak soru sordum 25 senedir de elektronikle ilgileniyorum PIC proglama işleri ile uğraşıyorum geçen de bu konuyu homemadecircuits adlı sitede ingilizce olarak sordum ve yazıştım ama mesleğim elektronik olmadığı için ukalalık yapmak istemedim her an yeni bir şey öğreniyorum öğrendiğim kadarı ile sorduğum sorunun pnp ya da npn olması ile bir ilgisi yoktur npn lerin tabanlarına + pnplerin de tabanlarına - voltaj uygulanır bu değişmez ancak bir transistör pnp ise o transistörün Esine ya da Csine + uygulanır npnde ise durum tersidir. Ancak genelde transistörlerin devre şemelarına bakarsan E'lerde ok işareti vardır ve genelde yük yani led C tarafına bağlanır. Ancak ses vb devrelerde bu bağlantı ters olabilir. Sonuç olarak bir transistörde bir led uygulaması yaparsan ledi C ya da Eye bağladında sonucun değişmediğini görürsün bu nedenle de hiç tanımadığın birine bunu sen de biliyorsun diyerek (benim ne bilip ne bilmediğimi sen nereden biliyorsun) vb ya da az bildiğin konularda ukalık yapma.
O öle değil biz meslektaş olarak bu islero biliyoruz aslinda tabi yanlis anlalqn normal çünkü biz sizle samimi bir arkadaş gibisinden yazdım bunu ukalalık olarak değerlendirmek doğru değil
