Aapki video ka har roj intzar rahta h
Aapne jo part change kiya h wahi problem mere suply me thi
Par output 12 volt fek aate h
Jaise hi lod dalo
voltage drop ho jate h
4 volt rah jate h
Aapse hat jodke binti h
Dumy voltage pe video banwaye
Please inzar rahega ❤❤❤❤❤
Ok brother, is vishay par bhi video aayega ❤️👍

Thanks a lot 👍
Sir Harveder
I have seen a lot of videos on CZcams regarding smps but your videos are nice please keep it up,by the way you were about to start ATX when are going to start them and thanks for valuable videos. I am from Hyderabad.
Thank you brother, I will start ATX tutorial videos most probably by next month ❤️👍

Very good job & nicely explained
Computer smps repairing kab shuru hoga ? Bahut din se pc smps repair video ke liye wait kar rahen hai, jaldi se shuru kijiye !
Half Bridge SMPS par thodi video aur banengi, uske baad Computer ATX SMPS ki hi baari hai dost ❤️👍
Always I am waiting for ur videos sirji. Very good explain
So nice of you brother ❤️👍
Beaut badia sir thnx
Shukriya Dost ❤️👍
Good work
Thanks brother 🙏
Excellent video
Thank you very much brother ❤️👍
@@vccground-hindi Sir aap desktop PC ke SMPS bhi repair karte hai kya?
Thank
Welcome brother ❤️👍
Wow amazing 😍😍🤩🤩🤩
Many many thanks brother ❤️👍
Sir ji pranam ❤ bahut bahut dhanyawad video ke liye maja aaya per aap video ke end me digram par explain kar ne Wale the na?
Isme diagram me explain karne wala kuch nahi tha dost. Jab hoga to jarur karunga 👍
@@vccground-hindi thik hai sir ji, pranam
Nice video best. Method. Fault finding
Sir I liked your all video thanks
Thanks and welcome brother ❤️👍

Very good
Thanks brother ❤️👍
PFC xerox colour copey SMPS=❤=expelanation🎉 please SIR😊
Input blinking.. Or output vi blinking.. Ek video banao sir
Ok brother ❤️🙏
sir ye jo transistor ka Resistance change kia hai 2.5 ohms ye transistor ki gat ko ja rah ta ya source par please to confirm me
sir apki video main jo hum ko pasand hota hai wo video cut cut na karke maza ata hai ap jitni be lambi video bana de hum ko acha lag ta hai
Gate MOSFET me hota hai dost, transistor me Base hota hai. Ye 2.5 ohms ki resistor transistor ke base par lagti hai.
Informative vedeo. Thank you so much God bless you.
Thank you so much brother ❤️👍
very good and thanks
So nice of you brother ❤️👍
@@vccground-hindi Thanks a lot sir G
Sir jee computer ka power supply ka video bhi banaie
12v 32amp wala
Agla series ussi ka hoga dost ❤️👍
I thanking to you for this good way of explanation .please tell me. Normally how much biasing transistor need in SMPS.weither the transistor used in cct MOSFET or normal transister.i need to know the biasing. Thanks for reply if you can...
What do you mean by biasing transistor ?
Sir mobile charger mein without tl431 ke feedback wale smps ko reparing ka video daliye
Usme ek zener diode laga kar hi feedback dete hain dost...video banane ka koshish karunga 👍
My question is not related with the faults in this power supply. But it is related with use of capacitor which has high voltage values and situated in between ground of input voltage and ground of output put voltage. I think in this board it is placed near input 110/220 voltage selector switch.please enlighten us why it is used and how do we calculate its value? Thanks
Best
Thanks 🙏
Nice video
Thanks brother 🙏
Sir good morning her bar ki tarh nice 👍 video sir ❤❤
Thank youu brother ❤️👍
Pl. Do another like inverter welding machine
We will do that too later...
गुरुजी e rickshaw charger 48 volt को भी with section के detail में समझाए 🙏🙏🙏
उसके लिए एक अलग सीरीज शुरू करेंगे तब बात करेंगे दोस्त ❤️🙏
गुरुजी ई चार्जर की सीरीज कबसे शुरू कर रहे हैं मैं बहुत आशान्वित हूँ आपका ऋणी लाहौरी
दोस्त, हाफ ब्रिज के बाद कंप्यूटर smps की सीरीज करनी है। उसके बाद फिर देखते हैं इसको भी...👍
Thanks
Welcome brother ❤️👍
Sir app pasand ke bat Kari ho itna to ham ko sharohkyan ke move pasand nahi gitni ap ke video
Sir haf brige SMPS me resistor gala huya tho kese velu nikale Esme tho alag alag velu rethe he video banaya
Kuch values experience se pata hoti hain, kuch circuit diagram me mil jaati hain aur kuch calculate ho jati hain. Bas isi tarah kaam hota hai dost ❤️👍
Sir plz kam output voltage k fault ko trace karnay ka tareeka fault primry side ka ha ya feedback ka kaisa dhondan
Uss par bhi video banayenge dost ❤️👍
nice Sir
PCB के गलत प्रिन्ट जान कर काफी निराशा हुई हमारे जैसे बन्दो के लिए ये एक बहुत बड़ा सबक है साथ ही आप कॉयल पर ड्राई सोल्डरिंग बता रहे थे वो सोल्डरिंग करने का व्यू वीडियो में नही आया या आपसे ही छुट गया अगर ऐसा हुआ तो उसका प्रभाव क्या होगा ? ये बताने की कृपया करना - धन्यवाद
वैसे तो गलत प्रिन्ट की समस्या काफी कम होती है, पर फिर भी कभी कभार हो ही जाती है। तो इस बारे में भी ध्यान तो देना ही पड़ेगा। कॉइल की ड्राई सोल्डरिंग मैंने फिक्स कर दी थी। ऐसा न करने पर लोड पर आउटपुट करंट में कमी आ सकती है।
@@vccground-hindi thanks 🙏
Sir please up computer ki smps repier ki video banaye a Mera request hai
Next month se computer ATX SMPS par series shuru karenge dost ❤️👍
@@vccground-hindi thankyou sir
Dear sir, is power supply me input aur output ki Isolation kese ki gai he please is ko explain karen.
Transformer se hi isolation hoti hai Sir...
Dear Sir, I have got the 12v SMPS for repairs, I am starting a all new on SMPS repairs. It would help if you can share the list of Resisters along with their power ratings for my stock.
I'm planning a video on, "What are the most used components in SMPS repairs". Kindly wait a few more days..❤️🙏
hello sir ,
1 sir aapki computer smps supply ke baare me koi video hai to please link send karna.
2. sir kya hum kisi tara se Smps ki ampere ko bada sakte hai..?
Computer ATX SMPS par video next month se aayenge dost. Current sense resistor ki value Kam karne se SMPS ke ampere bad jate hain par jyada current badane se circuit damage ho sakta hai dost...
hello sir,kya ap variable resistor ko permanent resistor k saat replace karney per tora baat kar saktey hai.i need it in local ups trickling kit.variable resistor boht jald kharab hojate hai,islye bar bar change karney se behtar hai,k permanent solution ho.
Kar dunga dost ❤️👍
@@vccground-hindi ok many many thanks to you.
Sir same SMPS hai , out put ki do transistor short hua thaa Maine badal diye .
Series lamp se testing kar rahe hai to bulb glow ho raha hai aur out ki do transistor over heat ho raha hai .
110 - 220V ki switch 220 v pe hi setting hai.
Keya problem ho sakta hai sir .
Out put ki do diode ok hai .
Transistor ke parallel me lage diode check karo dost ❤️👍
इस transfarmer से powerfull inverter बनाया जा सकता है क्या वह कामयाब होगा l
नही दोस्त ...
सर शंट रजिस्टेंस के बारे में डिटेल में समझाएं
ठीक है दोस्त ❤️👍
Sir, how to check the inductor value with meter plz
You need a LC meter to get the accurate value of an inductor. All other methods are just approximations only...
Sar ji 220 volt 110 volt switch ka kam kya hai iske bare mein bataen aur iska upyog kahan
Video number 73 me poora explain Kiya hua hai Dost. Aap V73 dekh lijiye 🙏
Mere pass12 volt 41 amp spms he usme smd ic and smd transistor Burn hua he, Sir bataiye please usme module use kese kare
Aapke SMPS ki dono taraf ki photo whatsapp Karo mujhe ❤️👍
Sir ap na galti sa resistance mode ma voltage check kiya par ap ka meter ko kuch nahi hua par mera pass aneng ka multimeter tha uski frequency range 2Khz thi or ma na halti sa us ko fly back smps ki frequency check ki to us ka baad vo jis mode pa set karun to vo set hi nahi hota kya uska koi hal hai
Meter repair karna padega dost ❤️👍

Please ignore about location of capacitor in my previous comment. I came to know that it is BRC thermistor. But original question is same
Sir mobile no dalo
Description me hai dost ❤️👍
Sir double transistors aur double MOSFET me led se kya drive volt check kar sakte hai aur kese
Same Jaise single me karte hain dost ❤️👍
Good
Thanks brother 🙏
Sir... mujhe ampere samjh me nahi ata .. jaisa...0.6amp. Jyada hota hai.ya 1amp jyada hota hai a confusion rahta hu hamesha
Are dost, aap ampere ko paise aur rupay ki tarah samajh lo. 0.6A ka matalab 60 paise, aur 1A ka matalab 1 rupay. Ab batao kon jyada hoga ?
@@vccground-hindi dhanyawad 🙏 Sir..
