Sir, aap jo batate hai, bilkul barabar samaj me aa raha hai. Lekin samjane ke liye jo method batate hai uske piche ka logic kya hota hai wo bhi please bataiye.
Feedback aane se se pehle optocoupler ki pin 3 aur 4 ke beech resistance high hoti hai. Isliye LED dim jalti hai. Jaise hi feedback on hota hai, 3 aur 4 number pin ki resistance low ho jati hai aur isi liye LED full bright ho jati hai...bas yahi logic hai dost ❤️👍
Sir 5v supply output pr diya gya hai.
Led Optocoupler ke pin 2,4 pr connect hai jo transistor ke emmiter aur collector hai pin hai.
Sir Question yah hai ki transistors ke Base pr Beena trigger kiye bina (current) LED on kaise ho gya.
Kyoki emmiter aur collector ke beech me base hota hai.
Jab tk base pr koi current dege nhi to transistor switching ki tarah kaam kaise karega.
Please sir yah concept samjha dijiye.
Transistor ko trigger karany ka kam led kar rahi hai jo coupler ki 1 aur 2 pin py lagi hai anode to cethode
@@sanjayyadav2263 yahan sirf optocoupler hi nahi laga hai dost. Circuit me dusre components bhi Lage hue hain...unme se kisi component se kuch leakage current aa raha hai, jiski wajah se bina feedback bhi LED dim on ho raha hai ❤️👍
बहुत अच्छे से समझ गया, शानदार प्रदर्शन
शुक्रिया दोस्त ❤️👍
ईद मुबारक 🙏

❤️❤️❤️❤️❤️ Great, Wanderful sir!
Ho sake to Computer SMPS diagram details video kabhi jarur dijiyega.
Smps secondary section me ampere kaise badhte hain jaise ki 10amp, 20amp etc details video hota to achcha hota...🙏
Wo bhi banana hai dost, bas ek baar ye flyback aur HalfBridge SMPS khatam kar lu bas 🙏
Ok Boss! ❤️
Kuchh bhi akela samajh ke repair to Karti hun, per usmein bahut hi samay lag jata hai.Isiliye details mein Janna bahut jaruri hota hai (Alag alag section ka kam Kis liye, Kyon, Kaise hota hai). Aur iskeliye ho tum, mujhe to lagta hai Pura RUclips per! 🙏❤️👍
Great solution, Sir 🙏🙏🙏💐💐💐
Keep watching brother ❤️👍

Bahuth dhanyawad sir
Feedback chak karne bhut se tarike ho sakte ye apne mind par hai bas hame feed back mai lage componet ke jankri ho jaise ke led ke jagh maitimer laga kar 431 ke pin par voltege dekhker or ha ager suply mai koi bhe falt ho or ye lage ke hamari suply series mai bhe khrab ho sakti to bulb ko main filer ke bad lagana ak sahi seris aap sir ji apna gyan bat rhe hai to gyane badega he dhanywad❤
Bahut khoob dost ❤️👍
sir hum ne apki sari vedio check and watch kia hai bahot badia hai bahot ala hai magar sir please ap kuch aisa video be bana k upload karday jo k baday smps ka ho exmple 20 am 30 am 40 am ka ho aur kuch aisa video be bana dalay jo 250 watts se lekar 2000 watts tak ho jo battery charger ho and 12 volts to 220 volts inverter ho apki video se hamin bahot faida milta hai god bless you
Dost dheere dheere ab badi SMPS par hi videos banaunga...❤️👍
Supper Sir.....The mind becomes happy.🙏🙏🙏......
All the best brother ❤️👍
सर 110v के लिए भी क्या करना चाहिए इसका विडियो बनाये.... इस विडीयो के लिए Thank you sir ❤❤❤u
आपका कोई जवाब नही लाजवाब है आप। 5v या उस से ज्यादा का source क्या है video में नही दिख रहा है ❤
ये वोल्टेज मेरी वेरिएबल पावर सप्लाई से आ रहे हैं जो मैंने काफी पहले बनाई थी। नीचे दिए लिंक से आप उसका भी वीडियो देख सकते हैं दोस्त ❤️👍

सर information is good Lekin sir har samay yahi SMPS nahi aayega to dusare SMPS KO येही ट्रिक use करके देखता हू sirji nice sir
Jaroor dost ❤️👍
Very good information
My pleasure 🙏
THANKU SIR🙏
Very useful information ❤
Glad you think so brother ❤️👍
Good information sir.
Thanks and welcome brother ❤️👍
Thanks a lot 👍 sir....
Very smart....thanks....
Glad you liked it brother ❤️👍
Sir एक जरूरी सवाल है कि अगर mosfet एक से ज्यादा है तब क्या किया जाए circuit कैसा होता है कैसे Repair किया जाए जैसे 13009 के 2 या 12N80 के 2 या ऐसे ही electric vehicle के smps men 68 amps and 600 v के 4 mosfet होते है उनको कैसे समझा जाए और Repair किया जाय... 5L0380 जैसी HIGH AMPS में कौनसी और STR हैं... जैसा आपने एक MODULE बताया 5V से 24V का पर उसके अंदर तो 8 AMPS का ही MOSFET था और आपने उसे 20AMPS में लगाया तो FULL LOAD पर क्या होगा और ज्यादा AMPS के लिए क्या किया जाय जैसे 24V 10AMPS / 20AMPS... ईन सभी सवालों के जवाब जरूर से देना SIR आपकी VIDEOS से काफी अच्छी जानकारी मिली... THANKS
2 या 4 मॉस्फेट/ट्रांज़िस्टर वाले सर्किट पर आगे की वीडियो में बताऊंगा दोस्त। अभी ये सब बताने से किसी को कुछ समझ नही आएगा। इसलिए धीरे धीरे उस तरफ ही बढ़ रहे हैं हम। 5-24 मॉड्यूल में जो 8A का मॉस्फेट लगा था वो प्राइमरी साइड में स्विचिंग् करता है। और एक स्टेप डाउन ट्रांसफॉर्मर में सेकंडरी साइड का करंट हमेशा प्राइमरी से कई गुना अधिक होता है। इसलिए 8A मॉस्फेट से प्राइमरी में अधिकतम 8A करंट बहेगा, परंतु सेकंडरी में वो बढ़ कर 30A से अधिक हो जाएगा। यह सब एक वीडियो के माध्यम से समझाऊंगा आपको ❤️👍
You are great sir thank s
Welcome brother ❤️👍
Ye Jo PCB ke back side me aap circut ka symbol bana Kar samjhate h na wo bahut mast h
Again thanks.
Always welcome brother ❤️👍
धन्यवाद आपका।

Sir aap jis tarha batate ho bahot ache se samajhme aata hai.... Puri detail ke sath... Aapke sare video ache lagte hai... Sir mujhe 1 puchna tha. Mere pas HLG-320 h 24 volt 18 amp power supply hai... On karne par relay tak tak continues aavaj karta hai.. Kya problem ho sakta hai lplease bataye 🙏🏻
VCC voltage nahi ban rahe honge. Secondary rectifier diode short ho sakta hai. Ya phir feedback section ka fault hoga dost ❤️👍
@@vccground-hindi dhanyavad sir check karta hu
Masha Allah ❤️ Good sir G
Thank you brother ❤️👍
Good job bro ❤

Nice sir👌👍
Thanks.
Thanks sir
1 अगर o/p में 5v के बदले 12 या 15 होगा तब क्या और कहा चेंज आयेंगे या नही
2 और अगर O/p 5v के बदले कम देती है तब
3 और O/p 5v ke बदले 7v तक बढ़ाने है अथवा 5v के बदले 3.3 कैसे करेंगे
4 और dth वाला smps से शॉर्ट किलर बनाए तो ये smps डेमेज हो सकता है

अगर smps की O/P 12 या 24V की होतोभी एकर्तनल सप्लाई 5V ही देनी पड़ती है क्या प्लीज
नही दोस्त। ये वीडियो सिर्फ 5V smps के लिए है। 12V या 24V के लिए मैं जल्दी ही दूसरा वीडियो बनाऊंगा ❤️👍
@@vccground-hindi thanks sir
thanx janab

जानकारी अहम थी परन्तु लो वॉल्टेज पर Led का dim जलना क्या pwm साईड से कॅप्सटर आदि के सीरिज के कारण ऐसा होता है क्योंकि टॉजिस्टर तो off position में है
Sir tl431 ke kharb hone y'a anya secundry component fotty hone se ower voltage Caise find karenge short video me explain. Kar de. 😊👍🙏🙏
Liked full Wacted form 😊😊uttrakhand
हल्का सा ग्राउंड पोटेंशिअल pwm ic से मिल जाता है, इसलिए led हल्की सी जल जाती है ❤️👍
Sir
Nice tip for FB testing
Vandanabhinandan
🙏🙏🙏
very good sir.kya aap ek video electric vehicle ke charger par bhi bana sakte he plz.jese 48v,60v,72v etc.
Kuch samay me wo bhi banayenge dost ❤️👍
You are great
You are also great brother ❤️👍
Very good
Thanks brother 👍
❤ achhi jaankari hai super
Sir ek led lekar uska ek sira yadi main capasiter ke nagative par jode or dusra sira led ka ic ke gate PE jodke yadi chek kare to kya feedback section chek ho sakta hai ?
Nahi dost, aise check nahi hoga...
Sir dth ki SMPS mein itne sare taar kahan se nikalte hai or kya kaam aate hai please sir video banana aap bahut achchha samjhate ho
DTH board me 4-5 alag alag voltage use hote hain, unhi alag alag voltage ke liye alag alag taar lage hote hain dost ❤️👍
Nice informative video
Thanks brother ❤️👍
very nice sir 🌹♥️💯👍👍👍
Many many thanks brother ❤️👍

Good job super❤❤❤❤
Thank you brother 🙏
Salam, very interesting. How many volts is the LED taking when full bright ? 5v ? Thanks.
LED always takes 1.2v, rest voltage drops on series resistor brother ❤️👍
sir thank you
Most welcome brother ❤️👍
Very Very nice
Thanks a lot brother ❤️👍
Very nice information. But sir some power supply feedback control MCU.
Didn't exactly understand, what you want to ask ?
@@vccground-hindi actually I told that some power supply feedback control mcu like sumsung AC PCB.
@@susantaatha6468 That could be a different concept also. I'll cover that too when I make videos on AC PCB 👍
Nice video
Thanks brother 👍
Dear
Guruji
Very useful and informative vedeo
Kya 50 v ka smps agar 7 v dera hai
To kya isi tarah 5 v se test hoga feedback. Pls reply
Tks
50v me is tarah nahi hoga.
Dear Guruji
Tks for reply our comment.
Then how much output till voltage
Can chechk by this method.
Can check 12 v output smps also
Check like the metod.
With thanks
Good 😊
Thanks brother ❤️👍
V nice
Thank you brother ❤️👍
एक और सवाल sir की आज कल led bulbs और tubelight में load के अनुसार wattage के अनुसार Volts जो change होते है एक rang में या wattage भी change होती है वो कैसे होती है उनके circuits कैसे होते है और अभी के phones के super fast chargers me 5/9/12/15 volts कैसे adjust होते है अपनेआप...
sir g power supply agar 5 volt sy zeada ho to led k 1 leg k seares mai 1k ka resistense laga dena chahey warna led jal jaege . im i right.
Nice 👍
Thanks brother 🙏
सर जी 3525 ic मे फीडबैक सेक्शन कैसे काम करता है इसे कैसे चेक करते है e riksha axiom charger मे amp कम या ज्यादा कैसे करते है plz सर मुझे बताये सर जी क्योंकि आप की वीडियो से मै बहुत कुछ सीखा हु
Dost jab e riksha ki series shuru hogi, tab yeh sab jaankari usme dunga aapko. Abhi kisi ko kuch samajh nahi aayega 🙏
Sir,ev charger 70v,10amp par ek video banaye
👌👌👍👍
Sir 🙏
Aapne 5 volt me kar dikhaye agar a 24 volt me ho to kya led kharab nhi hogi /our aisa hi led glow karegi ,so I hope you solve my confusion. Lot of thanks sir
Usme safety ke liye ek 1k ki resistance LED ke series me laga lena dost..Ab itna to aap bhi jaante hi ho na 🙏
You are really great sir
Ise repair ka pura video banye voltage fluctuations
E Scooty k charger me feedback section kaise chek krna he sir please is pr video bnaiye sir
Thoda intezaar karo dost. Ye sab ebike series me discuss karenge. Abhi kisi ko samajh nahi aayega. Step by step chalenge to sabko fayda hoga ❤️🙏
Sir can u make video about maltiple output power supply like 3.3v 5v 12v
In one pcb . How to divede the voltage after chopper transformer or shotkey diode to get multiple voltage
3.3v is made using a linear regulator while 5v, 9v, 12v or higher are generated using different secondary windings.❤️👍
@@vccground-hindi sir pls make the video about this topic in up comming videos
Am waiting for this type videos😀
Sir ye tareeka 12 volt sply mein bhi istamal kar sakten hein
Bilkul dost, kar sakte hain. Safety ke liye ek 220 ohms ki resistance LED ke series me laga lena ❤️👍
Tested in 12 supply and found OK
I wants to see all episodes which u posted for smps, can u guide me?

New circuit design karne ke liye hume PWM ic kaise select karen, transformer ke bare main agar pata hai to kaise ic chose karen
Ek Naya circuit design karne ke liye aapko har component ki jaankari honi chahiye ki wo kaise kaam karta hai aur circuit ke hisab se uski value kaise calculate ki jaati hai. Ye ek bahut bada vishay hai, jisko Mai ek comment to kya ek ghante ki video me bhi poora nahi bata sakta. Ye Advance topic hai, isliye is par ek video series banayenge dost ❤️👍
Sir Tl431 ko use na korke direct voltage divider resistance se optocuplar ko sala pate hai?
Chala sakte hain dost par ek dum accurate feedback chahiye to TL431 se hi milega ❤️👍
Sir ek 24 v 2.5A ka smps hai usme output diode SR5100 yani 5A100v hai isme SR360 DALA TO on karte hi diode short ho gya ye diode ke Karan hua ya koi secondary section ka fault hai sir.margdarsan kare please.
Aisa hona toh nahi chahiye dost. Aap dubara SR360 laga kar SMPS Bina load ke chalao. Agar Naya diode bhi short ho jata hai, toh output section me shorting ho sakti hai, wo check karo. Agar wo kharab nahi hota, toh load lagao. Load lagane par agar kharab ho jata hai to phir SR5100 hi lagana padega aapko...❤️👍
Sir Maine same procedure followed kiya lekin mera jo power supply hai wo multy voltage hai 12vdc 36vdc 380vdc uski output power fluctuation ho rahi hai maine apki procedure followed ki phirbhi nahi chalu hua so please help me 🙏
Voltage agar jyada hai to aap optocoupler ki pin 3 aur 4 par LED ki jagah multimeter laga kar resistance check karo dost...❤️👍
👌❤️sirji ld lcd laptop pcb circut board how work ❤️👌
