Raihan, I do not Believe the above circuit could be effective at that, as an alternative you'll be able to try the following design and style, and simply enhance the facility driver transistor and the current limiting resistor as per 10 amp output specs.

For an in depth description of pinout, dimension features, and specs download the datasheet of LM317

considering the fact that yur utmost operating voltage is 130V so the two the transistors will perform and equally is going to be Safe and sound.

The voltage formulated throughout R4 resulting from overload are going to be divided by P1, and when this likely will become enough sufficient to induce T3 only then the current Handle will kick in. So put in place the T3 area to put into practice this optimally

I feel it is possible to charge a sixty amps battery thru this my transformer. I need your recommendation and suggestion about most convenient of adjustable volts and currents circuit. many thanks

6 + D4, it starts to rob current through the foundation of This autumn stabilizing the voltage. R6 can now be a far more significant worth and isn't crucial as 1k would do properly. R7 and R8 will likely give a far more easy adjustment.

and yes once the circuit is dealing 100A, then T2/T3 might also here need to be upgraded for better basic safety. You can utilize 2N2222 for T2/T3.

Please sir, can I make use of the 43.9v with the series link about the modified style by Nuno Figueiredo?

Hello Imsa, including 4nos of 2N3055 to the above circuit is probably not a good suggestion, as a substitute I'd personally advocate you seeking the following circuit:

the benefit of this circuit, we are able to make use of a very small recent to Zener diode and base of the transistor. As a result, it's got a way more stabilized output.

make sure you I need you that will help advise which of your element(s) I want to vary or how to troubleshoot the challenge.

Ok sir now I fully grasp. But sir make sure you, 0.6v is it a ranking with the T3 transistor as Component of its knowledge sheet facts or that of diode. I'm inquiring this in the event of applying a distinct transistor for the same intent. God bless you.

But It's not necessarily problem if I exploit common scheme with latest Management? I've all compoments. convey to me make sure you which wire widht I would like on PCB. exactly where is biggest latest im scheme. Im starter. Thanks!

It is the exceptional voltage expected throughout foundation/emitter of all silicon BJTs for switching ON totally. So other than Darlington transistors, all BJts will have the exact same prerequisite of 0.6 V threshold across their base/emitter for total activate.
