2N3055 - this brings tears to my eyes as I first used them over 50 years ago and even made a class A power amp with them..

I made amlifire , inspired from your video and it's working very well thank you sir . You are a Good teacher.

Beautiful. Very clear and no confusion bcoz u understood ur project. This comes from one who knows little Hindi and knows some electronics. I'was a collegiate English lecturer.

Sir ji your explanations on every project is vey simple and lucid and practically genuine. Thank you.

Sir the way you explain the circuit is superb and clear every aspect. Thank you so much for making such a good video 🙏🙏🙏🙏👍👍👍. I use to see your video with patience till end and feel good. Complete practical and theoretical knowledge you have. No doubt. Thanks again.

Very nice! I do not belong to this field. But I fully fallowed this event. I picked the function of bridge rectifier along with the filtration function of a polar capiceter. I already know about the base, emeter and collecter. Use of connecters is a good idea. Interesting and informative. Thanks!

Before 2 month,I have made 24V 3A power supply with 2n3055 ,It works and I have also checked it on Oscilloscope to see noise It is absolutely noiseless and most of the current amost all passes through 2n3055. 0.5V drops across Transistor and get 23.5V . I m using this supply for my DIY cutting saw

Bhot simple or acha treeka sa samjata ho app 🤗

When making a regulated power supply, the regulated voltage should be slightly higher than the required voltage. Otherwise it won't get 12v. Also 0.7voltage drop in diode should be considered. good video Sir

Your video tutorials helped me a lot. Learned so many things also applied it in real and successfully finished my project. Thank you so much brother. Want more from you. Love from Bangladesh ❤️❤️

Very good sir , it's very helpful for iti,diploma and b.tech ece students .

पहले की तरह बताएं तो ज्यादा अच्छा है यह भी बहुत सुंदर था किंतु छोटे शहरों में यह कंपोनेंट्स आसानी से नहीं मिल पाते हैं धन्यवाद

Right sir ye 5 amp ki dek li tnx alot

Knowledge about power transistor is my gain today, thanks.

This is an excellent presentation. The simple flow of narration (with no-nonsense talks as in most Utube videos) is interesting to hear. Found the experiment very worthy and thought-provoking. In my opinion, you do not have to get back to the old version of showing circuit connection step by step. This is not necessary after the crystal clear diagrammatic illustration you have shown. Keep it up, my friend. We need authentic videos like this. 1. I have a proposal. Can we move beyond and complete this assembly of components by adding a knob or two so that voltage or current or both could be regulated with a volt amp meter display? 2. My suggestion: How about adding an LED on the PCB so that the input alert can be signaled and getting a shock could be avoided. Looking forward to your future videos.

सर मोबाइल चार्जर बनाये जो 5 एम्पीयर और 18 बाट का क्यों कि आपका जो समझाने का तरीका बहुत ही अच्छा है इसलिए आपको बार बार नमस्ते

Good circuit and good explanation. Thank you sir.

Koi bat nahi apka tarika. Accha hai

Thanks Sir.. You solved many of my Problems

Very well demonstrated - HOW TO MAKE 12v 10 Amp Power Supply

Very nice pra ji TKS you you made very nice power supply

The reason why your voltage is showing 11.45V is that you chose a 12VAC transformer, 12VAC is rms and converted to peak voltage is = 12*1.414=16.97V(at secondary side), now the peak voltage goes through the bridge rectifier and BR output is gonna be = (2x16.97)/pi =10.81V, 10.81V is the dc input voltage your regulator is gonna get and lm7812 minimum input voltage should be 14.5V and max 18V to work properly. your voltage will drop more as you attach high load on output and the circuit will work inefficiently.

Sir aap ki video bahut achhi original hoti he thanks

Excellent Sir. Sir I think it would be more beter if you plz show us the voltage drop at sources point (at main capacitor) & at output terminal, at base, collector and emitor of transistor including Amp meter. Thnx

Nice brother keep up ur good work 🌹🌹🙏

Sir many many thanks you.

Very well demonstrated. After applying full load, with another multimeter, the output voltage could have been shown. There by implying that output is constant.

Very good. But need SHORT CIRCUIT PROTECTION

Very good and informative video for power management systems, prajee badia👍❤

Very good video sir

Bahut achha explanation

Ye to achha video he but flyback smps transformer winding data calculation per video banaye

Very much useful tnks

Very very good presentation thanks

Informative Video Sir, I am searching this type of circuit, For Class D Amplifier, Bias voltage, 12v @ 3 Amps, It's useful for me Sir, Thank You 🙏🏻

Very effective presentation

Thanks sir Likeen Digram ke sath Regulater power supply ke bare Video banaye

ਸੱਤ ਸ਼੍ਰੀ ਆਕਾਲ ਜੀ ਤੁਸੀ ਬਹੁਤ ਵਦੀਆ ਪ੍ਰੋਜੈਕਟ ਬਣਾਉਦੇ ਹੋ ਜੀ ਧੰਨਵਾਦ ਜੀ ਕੋਈ ਸੋਲਰ ਪੈਨਲ ਜੌ 5 ਵੋਲਟ ਦਾ ਤੇ 500 ma ਦਾ ਹੇ ਉਸਦੇ amp ਵੀ ਵਦ ਕੇ 2 amp ਤਕ ਹੋ ਸਕਦੇ ਨੇ ਕੋਈ cuicuit ਬਣਾ ਸਕਦੇ ਹੋ ਜੀ ਮੋਬਾਈਲ ਚਾਰਜ ਕਰ ਸਕਦਾ ਹੋਵੇ

Super. Sir eak powerful amplifier ki video banado please 😭😭😭😭

Bahut Wadia dear

Wonderful 👍👍👍

Very nice and informative

I've liked it very much sir.

Nicely done

Sir, your way of explaining is excellent.

Well mounted and explained, but there is a better application, without any loss of regulation, using a 2N3055 PNP equivalent (MJ2955) and a emissor-base resistor as current sensor connected at 7812's Vin.

Very well explained tks a lot

Very good

Sir very very good presentation thanks.

Very good ....for beginners..... impressive....thanks lot....

Hats off to you..Simple circuit..well explained...pl clarify how to increase output voltage slightly..say 13 or to 14 volts in this circuit..and why the output was drawn through emitter instead of collector ?

Superb...... 😍😍😍😍😍

व्हिडीओ अच्छा लगा ,और आपका एव्सप्लेनेशन भी क्लीअर है/पार्टस सोल्डरिंग करके दिखानेकी जरुरत नही है/टेस्टींगवाला पार्ट जादा महत्वपुर्ण है/ गुड लक फॉर नेस्ट व्हिडीओज/

Thanks sir..🙏 ur theory explanation and practical is easy to understand...🙏

भाईसाहब....नमस्कार जी। आपका पावर सप्लाई के बारे मे विडियो बोहत अच्छा और ज्ञानवर्धक जानकारी वाला रहा है।....आपको बोहोत-बोहोत धन्यवाद करते हुए प्रणाम। 13volt और 20 amp या 40Amp फिक्स आउटपुट लेनेके के लिए क्या-क्या कंपोनेंट चेंज करने पड़ेंगे क्योंकि 12.6v की लीथियम आयन बैटरी चाजॅ करने लिए सोलर पेंनल पे लगाना है (जो सोलर पेंनल 18v से 22v निकालती है उस वोल्टेज को कंट्रोल किया जा सके...तो आप सोल्यूशन बताये )....Reply plz....Ⓜ

Sir Please Ek aisi video banaiye ki 25Volt ke Transformar se 25Volt AC,& 14Volt AC,kaise kare… Kyo ki 2.1 Amplifire circut me Bridge rectifier hai Dono hi Supply AC me Chahiye

Very good video. everything is fine, keep it up👍

Sir, aapke circuit ideas bahut practical hote hain. Sir jaisa ki market mein bldc ceiling fan ka chalan hai, but problem hai ki ye ek number pe bhi kaafi tez chalte hain, jis-se raat mein fan chala sona mushkil hota hai, orient company mein problem jyada hai, solution samjhaye. Please

Me like kar raha hu par like ho hi nahi raha he kya baat he sir

Bahut achha lga

What is your suggestion to use 78H12 rather than 7812, to obtain 5 Amp.@12 V regulated Output. Well, I must pay my gratitude for your really nicely explained videos. Super liked, Subscribed as well.

اسلام علیکم ورحمۃ اللہ وبرکاتہ ویڈیو بہت ہی اچھا ہے لیکن بھائی جان ایک ایک پرزے کو لگائے اور بالکل طریقے سے بتائیں زیادہ بہتر ہے اور ویڈیو اگر لمبی ہو جائے تو کیا فرق پڑتا ہے

Simple & min component used, nice videò.

Great project Sir.🙏

To test 12v/5A. The transformer must and should be15v/5A should be use The load must 2.4ohm 60 wat Rheostat. So Rheostat must me 5ohm 6 amp must use because after warming Rheostat small resistance value changes even heat sink must some more big size must used in order to get good life of the transistor with heat sink paste

Nice

Great information

Acha laga but out put experience kam aya ham isme kuch aur smps ya charger ka circuit le sakte he ' but hame watt bhi samajh ayega please ek video is par

Thanks sir ,very usefull

Too good, explanation is superb

very helpful video

Very good master

Nice. Now required one converter In put 24v Dc. out put 13.5v Dc 40A.

I want to see how you setup components fix ,it's very comfortable with me because I m fresh Lerner

Thank you very much sir ji.....

Thank you sir Very useful for me

Nice sir.thank you

Good:- basic-perfect & easy design but

thank you sar , ismai kam jyada karne ke liye system aur bataye .

excellet Sir

प्राजी चंगा जी 👌

great video sir as always

Good work

Great

Good video.... 👍👍👍👍👍

Very nice your projec sir, good job 👍👍👍

your project is very nice but it requires some components for better improvement. For instance , IC 7812 is grounded with forward biased rectifier dioide to aid 0.6 volt in the regulator output. So with 12.6 V output provided to the base of transistor will give you correctly 12 V output . Which is currently 11.4 volt . Secondly with high load current demand , obviously output voltage tends to drop from 12 V to 10 V because more base -emitter juntion is forward biased means more base- emitter voltage is required. Indeed this is accomplished by using the voltage feedback. Which is rather complicated circuit that gives stablized output voltage of 12 V .

I learnt a lot from ur videos sir thanks very much .l have question l am getting answer even from Google can u tell me what is the function of diode A64? .

Good job

Sir cap ke parallel mein resistence hota hai woh jab hum ac i/p karte hai tab cap aur resistence kaise kaam karte hai.is par vdo bana dijiye aur samjhaiye.

Thanks for very interesting explanation 🙂. Some time ago may be I used IC 7812 in To2 package which is similar to transistor 2n 3022

Sir great but volume use karty to or bhi ACHA hota Abdul haleem rind form Pakistan

Excellent

Fantastic

veryusefull vedio sir ji.where i can brought this ''ampere equipment''

Excellent. Son input voltage should be higher than output. 12v in 12v out is not correct. Also on output small value capacitor along with high value capacitor is also important and not optional.

Explanation is super..👍 after practical please explain with that circuit..🙏

Its fuantastic sir agar 3055 tr ho to 7812 ki kya jaruri hai

Its great 👍
