LM317 adjustable voltage regulator 0-30v 30A

lm317 adjustable voltage regulator 0-30v 30A

In this video I'm showing how to make simple and high power adjustable voltage regulator using lm317 with high output current.
As lm317 has max output 1.5A but here I used PNP power transistors to Bypass the current directly from input and voltage is managed by lm317.

You have a mistake there, parallel-paired transistors must have balance resistors, if they are not there, one of the transistors will be overloaded - they are not made with exactly the same values.

Nice day 🙂 Tom

Out put load is 30a, for that you have to solder atleast 4 sq mm wire, for loading 30a you have use common salt in plastic container, small motor consume less power.

1. What is the minimum input voltage?
2. Is it really possible to regulate from 0 V at the output?
3. What is the min/max efficiency?

Per funzionare funziona, ma mi sembra un circuito molto scarno privo di alcuni piccoli accorgimenti che reputo essenziali per una buona regolazione e stabilizzazione, tipo: diodo sul regolatore, un paio di grossi condensatori elettrolitici in entrata e uscita, resistenze di stabilizzazione, una su ogni emettitore dei TR di potenza.

I have a 40-volt source that I want to reduce. Is there any component in this tutorial that I should change to adapt the solution to a 40-volt source?

Nice video but where is the circuit diagram and you are only showing the voltage upto about 23 volts on no load and why can’t you show the amps upto 30 A to prove your circuit???

[Jonathan-blzv]

I know this is a old video, so hope I might get a answer. 
Where would you wire a amp meter into the circuit? 
Could you add another potentiometer somewhere to control the output amps?

En el video y titulo dices de un Integrado LM317, el diagrama a descargar es un IC 555. Donde esta el error?

[bvegass]

Good video

It would be good to put a meter not only voltage but amperes consumed.

[colinattwell]

Ok, good. But what about adding a current limiter, say to adjust max current from ~1A up to 30A.

[mharbuensuceso]

where did you get your input supply you dont show it why did you not show it ?

[somss]

Could you please make a video about 4v led dimmer circuit using potentiometet

[mrigankasinha]

Very nice 👍🌷
Q can I use the display took from an induction cook top (as salvaged item)
Q2what is the voltage you connect in I/p

[mlwasubramanian]

What about Current measurement?
How do you say 30 A.

[jordisau]

El circuito no coincide con la descripción.no consigo entender como el lm317 regula el voltaje solo te pido que revises el circuito que lleva 2. MJE 2955

[leopoldofernandezjr.]

Maybe the Amp is small bec of this ic Lm317.. this ic has very little amp.. just asking sir.

[benmahne]

Why you don't have the circuit diagram for the LM317

[michellevesquecouillard]

how do i get the pc board with all the component and how much does it cost me?

[Mproduction]

hi sir please make MOSFET using adjustable power supply and ampere or voltage adjustable shakeit make thank you and like
