in this video i explained in urdu / hindi language how does computer atx 200 Watt PSU SMPS switch mode power supply works. i explained diagram step by step so it will very helpful in smps troubleshooting and easy repair.
because the repair man must know how does the circuit works.
computer ATX power supply have input EMI filter, MOVs, NTC, dual line inductor filter bridge rectifier and capacitor to charge at specific dc level,
after that there is standby power supply which generates , VCC for PWM controller. PG power Good signal is generated after voltage level verification by level comparator. PWM controller receives power ON command from CPU and starts switching, which drives the Inverter section BJTs, MOSFETs, IGBTs, and we receive +12 Volt, - 12 Volt, +5 Volt -ve 5 volt 3.3 volt which is further purified by stabilization circuit. feed back circuit is used to regulate the output voltage, if SMPS makes fluctuations, or any voltage is over voltage or SMPS short circuit the OVER voltage protection circuit controls the output control pin of PWM controller, so that the output will off

So nice of you
i am thankful for your valuable appreciation
Sir would you kind to send ATX power supply circuit diagram please.
yes i will share link in the description. go to video description and download it
dell ki SMPS ke circuit bataiye na sir app bahut achha samjhate hai sir
dell ki supply PFC k saath, us per videos jald share karoon ga
زبردست سر

nice video sharing ji
Slm sir kindly solar inverter ki working principle per koi video upload karain . thanks
walaaikumassalam
Sir transformer ke sabhi type pe video banao...step up step down isolation signal abhi pe ..kaise work krta air identify kaise Kate circuit me use pin se
Assalm alekum sir ye video AP ki bhot zabardas hai jawab nahi
Assalm alekum sir tl494 ki ic pe smps hai 12 volt 10 amp ki os Mai 1 problem a rahi hai k wo volt tu de rahi hai 12 lekin amp nahi de rahi 13007 k 2 TR lage Hain please help me sir
Sir one thing I want to know is why the emitters of the two transistors Q3 & Q4 feeding to the driver transformer are connected to GND through two series diodes? Why not directly connected to the GND? What's the point. Please explain.
Sir iska diagram mil jayega hume schematic
In other circuit we see that there are two transistor in stand by power supply. But in this circuit only one transistor in stand by power supply. I don't understand deeply. Could you explain it by making another video.
Sir ye circuit diagram kese hasil krskte hen
sir atx power supply load pe voltage and current drop ho rha 12v and 5v
nice vdeo
welcome and thanks for your valuable visit. stay connected
Sir ap mere help nhi ker rhe he me ap se ketne bar request karu ke mere flyback converter me mosfet Or ic bar bar blast ho rha he Or mene rcd snubber bi laga raka he
Wow Super Sharing
Sir how to check board by voltage
yes sir yhi video iiske bare me or jankari dijiye
👌👍👌👍👌👍👌
best regards and special thanks
Ac ki pcb ke bare me kuch bataye aap Kafi acche se samjha te hai thank you
always good teach

welcome and special thanks for your valuable visit and appreciating my work. stay connected
first time on u tube i watched a video which explains industrial design of a power supply. learnt a lot from you. thank you!
बहोत अच्छा बतया
Informative video shared 👌👌 you explained very clearly and indicates all the small point ,this video is very informative for electrician.
Waiting for english version if it is possible regards
بارك الله فيك
Good tiching karte hai 👌👍👌👌👌👍👌
thanks a lot
Wahh bhai
Good job sir ji
zabardast
Thnks to hindi good ap ko jada barkat de.
thanks a lot brother
Sir aapka fluke maltimeeter kitne rupees ka hai indian money k hisab se
it is around 300-350 dollars, it depends on the suppliers.
remember to purchase FLUKE USA, there is a chines copy, that looks the same and very cheap price. but most of time the suppliers supply low quality with high price
Mashaallah sir, bahot bariki se smajhaya apne.
best regards
