This is a crude circuit that has the external transistors incorrectly connected. It is nothing more than a simple emitter follower that is outside of the control loop so the voltage regulation will be poor. There is not current limiting that is in any way predictable. The proper configuration is easily found in data sheets or applications notes for the LM317.
edit: Forgot to mention - the proper circuit requires a PNP transistor
ok thank you
Instead of criticizing, go ahead and make yours that isn't crude..We would be happy to learn something from you...
Yo hice un circuito de esos pero la realidad no conectar aparatos de alto amperaje probé conectar un taladro de 12 voltios DC y se destruyeron los transistores y regulador 😢😢
Hola. Que circuito hiciste ? Uno como el que se muestra en el video ? Estoy buscando un circuito para reducir de 50v a 12v con 40 amper pero esos transistores del video claramente no soportan ese amperaje
I've seen several people do this basic circuit but NO one is showing an amp meter or using a thermometer to check the heatsink to see how heat is being transfered to that piece. It is really important to know this to see how effecient the regulator is actually. These are nothing really more than a linear regulator and therefore cannot be all the efficient as there has to be lost power in heat. A switching system would be much more useful, For sure if all you want is a linear system then these are fine and simple.
Your built is neat !
thank you...
O problema destes circuitos caseiros ,e disto ninguem fala va-se la saber porque,e a sua queda de tensao,quando se aplica uma carga...uma lampada ou motor na saida de ajuste,ou seja por exemplo uma lampada de 12 volts 21 watts quando ligada na saida de ajuste a 12 volts reais,nao tem o brilho que deveria ter ao ser ligada a 12 volts reais,e se na maioria dos videos de facto mostra a lampada la ligada com os 12 volts e o brilho normal,e porque a voltagem la injectada de momento nao sao os 12 volts reais mas sim uma voltagem superior talvez 15v 20 v ou mais para ela dar o brilho normal,e para provar isso e muito facil em antes de por a carga lampada e regular a saida ajustavel para os 12 volts sem carga e so depois ligar a lampada,entao ai pode-se verificar a queda de tensao de 12 volts reais para 7 volts 6 ou 5 volts,porque de facto nao pode ter uma quebra tao acentuada,no aceitavel talvez 0,5 volts,dai a grande lacunas destes circuitos caseiros,nao quero dizer mal destes projectos e bem haja quem os faz e ate sao interessantes,mas na realidade tem este senao.
good
Why in the second TIP3055 the Collector is not used? I think this was a parallel setup or am I wrong.
The collector is connected with the heat sink.
What’s the maximum input and output current. I need to make something for my battery bank that’s 16.8v so that I can charge my 12v battery bank 👍🏻 thank you
Primeramente mis felicitaciones por su prollecto muy entendido y facil de hacer exitos en sus demas proyecto que dios le siga dando mas sabiduria e inteleigencia. Bueno amigo mi pregunta es la sigue te ! Si toca las 2 puntas de la salida se quemaria el circuito o alguno de los transistores ? Ya que no le veo un sistema de protecion contra cortocircuito es lo unico que le aria falta a este proyecto espero su respuesta gracias buen dia exitos en sus proyectos...
Bienvenido. Esse no arde. Pero no lo dejes demasiado tiempo. Porque no hay dispositivos de seguridad.
Esqueceu de ligar o coletor do segundo transístor que deve ser ligado tbém junto com o primeiro transístor no pinto de entrada do regulador
Автомобільний компресор можна під'єднати, щоб працював від мережі 220 вольт? На вхід подати 24 вольт і 10 ампер а на виході, компресор.
try,. but input DC
Sir please explain it lm317 range only 35volt
How possible in60 volt
Yes sorry
Muy bueno 👍
thanks
Good project, but you miss to solder the second collector of the the second TIP3055, why?
Yes it should be related. But it is connected by the heat sink. From the body of the transistor.
very usful vedio ....nice job...🤗
Thank you..
Excellent ❤❤❤
welcome
Greeting!
That's a good video!
It would take about 7V and more ampers about 15...
Can such a device work on these parameters for a long time and not overheat?
Thank you
use large size heat sink and cooling system.
Collector of the second transistor is left unconnected (tip3055)?
It is already connected to the heat sink.
Useful video sir thanks ,How can I use this video to controls the speed of a DC Motor (4KW/48V/1500RPM) Also how can I protect the mosfets used Thank you sir
I don't know what to do. but try.
Can it handle 12volt or more voltage 9amper current for long time like around 4 to 5 hours or little less?and can it decrease little voltage then 12 volt?
Yes you can broo. But big heat sink use. 👍
Can i use it for continuously 6 hours.. 12 volt 2Amp motor 555.. (24 watt)
Temperature?? Heat ??
use cooling fan
Hi, if I install the LM317HVT on the same circuit diagram instead of the LM317, can I reach 57-60V without changing anything? Thank you.
yes. chek the data sheet
great work
thank you.
I agree with unlimited code,why collector are not connected anything? I think this 8s wrong circuit. You have to to connect them as parallel or Darlington?
collector conet heat sink
What is the function of 0.1uf capacitor in this circuit?
Fuse nad amoothing

hi,i didnt see current-sharing resistor in the collectors...
They are important. Without them, bipolar transistors will not share current equally and there is a tendency for thermal runaway. If one transistor starts carrying more current than the other it will run hotter. That results in a reduction of the base-emitter voltage, meaning it will take even more of the current and runner hotter still. The emitter "ballast" resistors do increase losses in the circuit, but they are essential.
Sir Can I charge 4.2V 130A Battery Pack?
My need 4.2V 50A Output circuit. Please ans
Thanks from Bangladesh.
50A no problem. try bro. use a large heat sink.
what is controlled by knob (pot), voltage or current...? I think video is somewhat incomplete...
pot is potentiometer. voltage controll.
@@homemade_101 ok... and what about current (amps) control...?
Love your work
welcome
Hi, ur circuit is maximum 100v,50Amps, can I use this in 48v,50Amps to drive the bike wheel for a long drive.
🙄
@@homemade_101 hi,sir u only show me ur face,no comments, please gave me a good solution for my bike.
The Lm317 get really hot too??? Or just the 3055?
yes, i think only 3055

Is there any circuit for the protection if the -ve ND +ve probe is connected
No bro
Lm 317 can handle maximum 1.5amp ,so the output current will be around 1amp only,need othe transistor to boost ampere's also.As per my opinion.
60 volt x 50 amper = 3000 Watt yapar, 3000 Watt trafo varmı bu devrede ???
no
Is it possible to connect three of these in series from three different power sources? (batteries)
Ok no problem.
Nice
Hi sir,,, can this be used to inject voltage on a shorted motherboard,,,
This circuit will not blow or shut down then come back on after I release it from the shoerted board.
To make my question short and clear,, I am asking if this circuit will withstand short circuit on the load.
This circuit not have short circuit protection bro.
how much is voltage amp supply given?
30v 5A

No se puede conectar un taladro de batería ya probé y se destruyeron los transistores 😢
sorry
How is that lm317 Max volt is 40 n in title u said 60v
🤔
Hi there, thanks for nice contents you make . I need to design a circuit to control about 200 A DC . Actually I have a mining PSU and I need to convert it to a variable power supply with CC and CV . Any suggestion you can make ?
I will try it
Hello. When charging, my battery shows 13-16-18 volts. Can I stabilize it with such a regulator so that the output from the battery is stable at 12.5 volts while it is charging and the voltage on it jumps from 13 to 18 volts?
Yes charge voltge 13/16v in.
Sir,amp control kyse hoga?
no bro this is voltage only
Can we use for 12 volt dc cooler fan?
yes
apa fungsi transistor ke 2 (sebelah kanan).? colector tidak terhubung ke mana mana
It is connected heat sink.
👍
Es extraño 60volts ???🤔🤔🤔
Si el LM 317 puede regular asta 37 Voltios Máximos.!!!!
yes it is a mistake
How much will it cost to make this? dc motor speed load will be run more or less 4, 5 ampere will hit how circuit can be made to control motor speed
I think 8$/10$ 🤔🤔. Yes you can use motor speed controller
Even for you, this is a low point. You never connected the collector of the second transistor.
Voltage is adjustable, but not current.
And why not use a bunch of car headlights in parallel as a load, rather than a puny little flashlight bulb? Give us all a thrill and let us see actual high power.
collector was connecting across the heat sink
@@homemade_101 Sigh. Maybe it does and maybe it doesn't. The hole on a TO247 case is insulated. There is nothing in your setup to guarantee that both tabs will punch through the oxide layer on the aluminum heat sink, or that a low-resistance connection will be formed if it does. You could get away with this if you used TO220 packages as you have in other videos, but this one is just bad.
Also, while I have your attention, the thumbnail says 50 amps, and that is just complete and utter hogwash. You don''t have the base drive to do it, and the heatsink is completely inadequate. Like I say, I dare you to show a video of this setup driving 500 watts of 12-volt car headlamps. I double dare you.
It is misleading to read what is written on the transistor and put it in the title thinking it will be in the whole circuit. Pass 12 volts, 10 amps through this circuit for 1 hour. The circuit will burn. It will burn like crazy. It only works in small jobs. Efficiency is fifty percent.
yes
Can input 12vdc out 36vdc for led smd 200watts or not
