Best tutor over youtube 👍 tough topic to itna easy way me smjhana koi aapse sikhe sir🙏
its your greatness mam, that you are thinking like this.. have a happy time.
@@Techpatakha m instructor in government ITI rajasthan..we have this topic theory plus practical...I saw this video and learnt then I taught students how to repair and all🙏
Its my pleasure sir... Have a good day..
@@Techpatakha ☺️
Sir, After the rectifier the voltage will be about 170volts across each big electrolytic capacitor. In the video, you say 12V. One has to be careful because you will get a shock.
Yes, correct
v good sir
Thanks and welcome
Nice
Good
good
Great explanation :)
Glad you liked it!
@@Techpatakha can you do a video about the atx smps standby section working with circuit diagram
If 2 nos diode are used for rectification,this is known as half wave rectification,if 1no. diode is used for rectification this is known as quarter wave of rectification, If 4 nos diode are used for rectification known as full wave of rectification More over Ripple charges are filtered through Inductor and capacitor,thanks for knowledgeable SMPS power circuit video,It will be prolonged,thanks.
If one diode is used it is called half wave rectifier. If two diodes are used it is full wave rectifier (in this case centre tap). If four diodes are used then it is called full wave bridge rectifier.
Sabse pehele pakra geya.... Fuse yea Sahi tha Bhai🤣🤣
Awesome explanation. Bhai 2ndary me jo bari coil lgi ha, meri power supply me wo burn ho k dark brown ho gai ha aur supply on nhi ho rhi...
Can you tell me how it can be repaired? or make a detailed video. thanks.
Also outer 2 schottky diod lg rhy lekin middle me transistor lga hua ha I think.... Thanks
Thanks for your input.
Learnt a lot as you tried to explain with schematic which generally youtubers don't do. Infact, some of my doubts got cleared.
But, please don't mind there is a catch! Like others tried to bring out some of the other issues they noted. Likewise what I noted is that, not only as you figured out the connection points of Transistors, you have marked collector, emitter wrongly in the schematic; atleast, denoted wrongly in my opinion which may bring serious hazards if someone follows blindly at 15:24. Emitter is always the one with arrow, may it be in any direction. Collector has no arrow in it.
Emitter which is heavily doped and which emits electron in the circuit. And this direction of emission of electrons are showing with arrow inside Transistor symbol. Collector, as the name suggest collects Electron and hence, has no arrow marking in it. And Base is like a Gatekeeper to me who checks the ticket (sees biased voltage across it) and allow commuters to enter into platform, or similar.
Hope you will take care these things in future videos, because these are fundamental errors which is not at all acceptable.
My writing to you is not to defame you but alarming newbies
Thank you good Luck!
thanks for assisting me bro.. next time i will not repeat and have a great time ahead.. 🌼🌼
Sabse acha video smps ke bare me Complete video with schematic.. 🙏
Sir mera power supply on hota sab voltages show bi karta hai par usme chuiii... Karke awaz ati hai aur motherboard load nahi kar sakta
Computer start nahi ho raha
Kya fault ho sakta hai..?
Thanks sir I am also feeling much more learned keep up sir❤
Make video on the stb voltage 5 volt ( charger type circuit )
sure sir i will make
You are so good but don't go fast. let the video may go long.
1bar voltage ac se nikal kar Dc ban jata hai to current Diode se reverse Plug me kabhi nahi ataa.. Diode work only in forward bias.
Capacitor discharge ke liye resistors isliye lagaya jataa hai ki shut down karne ke bad supply 5-6 seconds me bandh ho jaye
Capacitor charge rahenge toh voltages slowly slowly kam ho kar bandh hoga
thanks sir that's very true..
@@Techpatakha sir I am right?
Apka video bahut hi acha & it's 1st video on TH-cam jo schematic diagram ke sath simple understanding wala hai 🙏🙏
70% knowledge.Main part 5v standby trigger voltage to turn ic on,to trigger all main voltages 12v,5v,3.3v.
If there is no stand by 5v present in purple wire,,then on to green wire from ic there will be no any output voltages,even if green and black wire is shorted.
ya that is true brother, you are right.. thanks for this deep and useful knowledge.. have a great time..
That's a very vital part of construction of this SMPS. As the name TRIGGER itself explains its work/function. To trigger/set something ON or OFF. In this case ON.
Thanks for your input and highlight
Capacitor and rectifier diode ko check karne ko bataya hi nahi genius
Very Presicely and beautifully explained
Show how to identify bad components and repair it without hand gloves. You are showing theory.
apna collector aur emitter sahi karlo siirji
Sir, yeh NTC parallel nahin huta?

How much voltage must be in between the standby transformer primary side ?
hello sir ji
please reply. mere smps me dc side ka capisitor 200uf/10v fata hua hai
kiski jagah koi or capisitor laga sakte hai
Sir better hoga same rating ka lagaye ... ya thoda sa jyada rating ka laga sakte hai, better hai aap same hi lagaye.
Sar SMPS loud nahi leta SMPS ok hay par car amplifiers may volume Jada kartahi bandh ho jata hay
sir shortky diods kharab ho sakte hai
Sir, i am getting low voltage 8.8v in 12v yellow line. What will be it's fault and how can i repair it.
is it correct to say Emitter as Collector, Collector as Emitter?
Agar 12v ki jagah 24 volt ya 36 volt output lena ho to kya kya change karna hoga
isme nahi hoga sir. hame 24 volts ke liye step up karna hoga.
Ntc will not be connected with negative input?? Doubt...

sir there must be a reset button just reset your power supply then start it -again .. it must be ok
Sir, in my 450w SMPS, 2 resistors were fired, which were below to 5v mosphet 2N60. But I could not able to find the value (ohms). Can you please help me..?
Are you talking about bridge resistors..
After repair smps all voltage fluctuate ho raha hai. Where will be the fault?
Body ho raha hain. Kon sa galad ho sakta ?
Mai jab apna Pc SMPS se +12v aur -12v yani dono 24volt se apna dc fan chalaya to almost 5seconds ke bad smps kharab ho gai,
Usme kya kharab hone ke chances hai.
Please reply me.
sir wo to ho hi jayega aapko 12 positive or common negative use karna chahiye tha -12 volt is for some other commands.. check the fuse

Bhai mera desktop pc ka plug laganay kay thori deer baad on hota hay taqreeban 15 say 20 minute baad,
aur ab sardiyoon mai tu 1 ghata baad pc on hota hay, lekin jab on ho ker garam ho jayay tu phir tang nahi kerta,
mager jab lambay time yahi 3 say 4 ghantay kay liya pc ko bandh rakho tu phir yeh masla dobara aa jata hay.
may nay motherboard ki battery bhi change ki mager masla sahi nahi howa.....
Bhai Yeh kis chiz ka masla hay powersupply ka ya motherboard ka? mugh ko tu yeh koi capacitor weak lag raha hay,
mager powersupply ka capacitor hay ya motherboard ka .....yeh nahi pata ?
Lekin power supply ki green aur black wire ko milanay per power supply ka fan foran chal perta hay,
mager powersupply ko motherboard say attach kernay per power supply foran on nahi hoti, 20/25 minute baad on hoti hay.
pls check the capacitors.
Sir pc ki power supply 15 minute me off ho jati hai usko kaise thik kare

Bhaiya Mere Computer Ke SMPS Se CURRENT Aata Hai, Maine SMPS Nikal Kar CHECK Kiya, SMPS ON Kartein Hain Toh Bhi Aata Hai & Jab Band ( OFF ) SMPS Mein MAINS SUPPLY Dete Hain Tab Bhi Aata Hai. Agar SMPS Ka Koi RESISTOR, IC, CAPACITOR, TRANSFORMER, DIODE, FILTER Coil, TRANSISTOR, MOSFET Ya Koi Aur COMPONENT KHARAB Hai Jiski Wajah Se SMPS CURRENT Marta Hai Toh Kaise CHECK Karein & Theek Karein ?
Apke computer plug jaha lagate hai waha Earthing Proper nahi hoga ya sayad missing hoga tab aisa hota hai
Bro mere ghr light jane k baad se power supply ni chl rhi... Kya problem ho skta h..??
Sir agar power supply me led show ho rahi hai.. to power supply ke pichhe reset ka butten hoga just press that for 10 seconds and then s/w it on again..
are you talking about home power supply... then check your MCB.
Nhi sir mere pc me i ball ki 450v ki smps lgi h.... Ghr ki light jane k baad se pc ni on ho rha h .... Mene sort krke dekha to smps ka fan ni chla....
aapne reset kiya usko... supply ke pichchhe ak chhota sa button hoga reset ka. . agar kar liya to fuse check kar lijiye... ak bar..
@@Techpatakha thik h sir mai check krta hu... Thanks for your attention 🙂
Bhai sahab aap to khud hi confused ho
😊
Sir ap ne power transistors ko ghalat define kiya hai...ap nay video mein collector ko emitter aur emitter ko collector define kiya hai....arrow ander ki janib ho to PNP aur agar bahir ki taraf ho to wo NPN hota hai dono positions mein arrow emitter he hoti hai..... Ap se galti se galat define howa hai....
i m really sorry for that. and thanks a lot for commenting sir. due to nervousness words slips. yep its right that arrow always shows more electrons. have a good day.
T1 & T2 ka Emitter Ko Bolte Hai Collector aur Collector ko bolte hain, Emitter? Bullshit.....Ulta Palta Bakte Ho Aap. Video banana Chor do.
