exactly what I was looking for, to teach as well as demonstrate. You earned a new sub sir!

[@TEKNOISTIX]

Thanks 😊

[@soumitraseth6921]

MANY MANY THANKS 👌

Fantastic !!
Nicely explained tutorial backed with knowledge and facts. Highly appreciated.
I just arrived and become huge fan of yours as your videos are completely filled with logical knowledge.

Bhai, aapne AC ko control karne ka banaya hai?

[@alexchandapillai9667]

Sir your video is superb ...can u add digital voltmeter ...so that we can see voltage and amps on voltmeter???

[@TEKNOISTIX]

Yes it can be added
I ll share the circuit in the description in few days

[@c.rajendranchinnasamy8929]

Very good video. All things well explained. Even an ordinary electronic enthusiast will understand the things nicely.
Well done again. Congratulations !

[@TEKNOISTIX]

Thanks 😊

[@engahmeds]

when the output current is 10A, each resistor has current of 5A, so the voltage drop on each one ohm resistor is 5V. in this case each resistor should dissipate 25W, while your resistors 5W only !

[@hp2073]

Yeah that's why the only people who compliment are beginners

[@wernerpeter9706]

Your calculation is only correct in the event of a short circuit. With normal use, a few volts should still be available for the connected load, i.e. the voltage drop across the resistors should not be 5 volts.
The weak points are rather the small capacitor after the rectifier and the undersized heat sink. Calculate the power dissipation of the transistors when a small voltage with a lot of amperes is set.

[@hp2073]

@@wernerpeter9706 no difference. Short circuit in a cc supply does not necessarily mean highest current. Power resistors are under rated

[@engahmeds]

@@wernerpeter9706 also in case of full load which is 10A , my calculation is correct

[@wernerpeter9706]

Sorry - that was actually a 1 ohm resistor on the emitter, so in the end I didn't look properly. Yes, you are right, this is a nice heater. 0.1 ohms would be enough to stabilize the load. But then there are still the problems I mentioned.

[@Victurf]

...If the voltage is close to zero volts and the current draw is 10 amps, each transistor will have to dissipate 150 Watts...

[@chandermohan453]

Gentleman, you have explained very clearly. You are a master of the subject.

[@TEKNOISTIX]

Thanks 😊

[@bachupattnaik5146]

The best video of this category. Very nicely and cleanly explained. ,👌👍

[@TEKNOISTIX]

Thanks 😊

[@JackSparrow-oq6iv]

You put 2 resistors 1Ohm 5W . If the output current is 10A it means that through 1 resistor flows 5A current. P= I*I*R in this case P=5A*5A*1Ohm=25W it means 5 times more power than it can reach ceause it's only 5W. Maximum output current you can withstand with these resistors is 4.5 A.

[@ravirao5798]

If it 4.5 Amps there will be a drop of 4.5 volts...

[@boonedockjourneyman7979]

This guy knows nothing. He copied this from a common exam question without figuring out the answer.
This is a sad statement of the clickbait coming from the Indian EE want-a-be community.

[@muhsen61]

If the transfomer is 30 volt out . This circuit is maximum 2 amps

[@nagarajn4972]

1405. Minutes. 0 is removed. Than the current is 2.5 amp

[@Paul.Smith1980]

This supply will not work the output voltage drop will be significant.Just put multimeter on this supply output.Then aimply attach a twisted pair wire on output without any load attached to wire u will see voltage drop.There is no load yet output voltage will drop.Transistor will conduct uncontrollable just with wire.

[@kkvishwanath8278]

I really like all ur projects as ur presentation has clarity with neat demo of both diagram n components.n very reliable.

thank you so much sirji aap bahot acche se padhate ho.
koi saval baki nahi rah jata. sab javab ek hi video me mil jata hay.

[@susantpal]

A pleasure to watch and learn from this video like your last one. You may please ignore my proposal I had stated in your last video comment because the same is very nicely answered here. Thank you once again.

[@TEKNOISTIX]

Thanks
I always try to go step by step in my videos
Firstly i covered the simple fixed power supply
After that in this video i moved to a variable one
And there is one more video in this series in that i have added a volt current display also and also assembled this circuit in a wooden box.

[@sanjaysonihisar6595]

Paaji tussi great ho... Aapne sab achhe se smjhaya

[@vigisbigtm]

Great explanation and demonstration. Keep up the good work! It would have been great if we could see how we can implement a voltmeter and ammeter to visualise the outputs.

[@planker]

Nice work using a audio power transistor for this. I am going to use this on a power supply that I built.

Thanks for the compliment
You can use the boost converter with 12 v output it will give you controlled output

Nice PCB TRACKS, good Video, Recti-Bridge needs Heat Sink for Max 10Amp Load.
For Current settings, we normally short output & adjust the Max Current limit, instead on load as is shown?

[@inderdasssetia5243]

Sir, your videos are very interesting. As regards variable power supply, is it possible to have provision for adjusting charging current in our Inverter when we replace the battery with a different AH value ?

You can Use this circuit as battery charger too
It can give you higher current
