I am happy to say this is a genuine regulator circuit - well done and nice demo

[@totalcircuit]

Thanks

Very well explain 🎉

One thing I need to know that can I use 50watt constant current led driver as an smps....??
Actually on 50watt led driver, it is mentioned that current is 1500ma max. and voltage is 28 to 42v dc...and I want 24v from this driver...

[@totalcircuit]

You cannot use LED driver as SMPS. LED driver has current limiting in its output, you cannot use it for 24 volts, it will be better if you install a separate SMPS for 24 volts

@@totalcircuit ok..
If I am using a buck converter and need 24v 1.2amp from this 50watt led driver...then anyhow is it possible..??
Plz reply me....??

I have been looking for such a simple and well-functioning circuit for a long time. I made it from an irfz46n and a bd142. The mosfet and the transistor are 55V, the lm358 is 32V, but because of the zener it gets a stable 5V. What is the maximum input voltage?

[@totalcircuit]

There is a circuit diagram in the video, you can make it by looking at it. This circuit has a maximum input voltage of 30v DC. A 5-volt zener diode has been used in the potentiometer for constant voltage. Pin 8 of LM 358 has been connected to the input voltage. You have installed your components correctly. There may be some mistake in the circuit. For more information, go to the channel and I have made another video of the same type, it works on 60 volt input. Thank you for watching the video. Have a nice day

@@totalcircuit I saw that video too, very good. I have an 18-0-18 transformer for this project, I would like to know if I can connect it to it, and if the buffer capacitor (4700uf/50v) will not cause problems? Anyway, I'm already at 35 volts, so far everything is fine. I think it should be able to handle 40 volts, since the mosf and the transistor can handle it, the LM358 doesn't get it because of the 5V zener. Once again, thank you very much, I'll keep experimenting with it if nothing else and see how it ends. If it works, I put 4 transistors (BD142 or BDY73 or TIP3055) on it with a resistor. I noticed that the mosfet doesn't even need cooling.

@@vatexvatex2667 You can put as many capacitors as you want, it will not have any effect on the circuit but according to the video in which you have commented, you cannot give it a maximum supply of more than 30 volts otherwise LM358 will get damaged and your variable supply will not work.
I have made a video of a circuit working on high voltage, I am writing the name of the video below.

Thank you

[@vatexvatex2667]

@@totalcircuit Then tell me what you measure at 04:40 in the video? Because I think that is the input voltage of the LM358. This is also confirmed by the fact that with a 30v input, the 5V zener fire is hot. So if you get a higher voltage, it will affect the zener, not the LM358. Since the LM358 receives a stable 5 volts from the zener.

[@vatexvatex2667]

I can't build the other one as I don't have such a high power PNP transistor.
