Thanks and welcome
Haseeb Brother. I am your regular viewer because I observed that your videos are fully informative based on technological and logical information. I found your videos better than any others on other electronic channels. Most of the people in this field are utilizing "Jugars" but you go deep in understanding the essentials of something. Keep it up.
Welcome and special thanks for considering my efforts as useful material.
please accept my best regards
Assalam o alikum sir. I have smps power supply in which issue is that there is 7 volt vcc if I remove the pwm i.c 3842b so there is 15 volt & I replaced the ic 3842b so there is 7 Volt again please please gauid me to resolve the big problem for me. Waiting for your positive response as soon as possible please.

Very nice information bro
Dear Sir, your videos are really worth watching. Your detailed explanation of the subject matter is commendable. I congratulate you on your efforts to post such useful videos, keep up the good work.
I would be grateful if you could provide a solution to a problem which I am facing with a 12V to 35-0-35V boost converter used in tractor amplifiers. (100Watt output). When I switch on the power supply, the voltage rises to 70V DC (+35V-0-35V DC) but after reaching a maximum value, it starts to fall slowly and the final voltage is around 20V (+10V-0-10V DC) The controller IC is L494 which is driving MOSFETS P55NF06. The transformer is a ferrite core toroid, primary 6 turns and secondary 18 turns. Please suggest some solution so that I can start troubleshooting this circuit. Thanks.
nice tutorial
very good helpful

Sir g agr ct capster ki value change ho jye kia tb bhi out put voltage kam ho jaty hain ?sir g aik vfd m ye essue chal rha hy mery sath plz guid
Thanks sir....very valuable information
Most welcome
Thanks Sir for your experiment sharing..... Sir plz. explain how could we define which part (primary or secondary) of a SMPS is defective, when output is flickering
i discussed all parts and possible reasons in this video.
please also check video number 34 , 97 , 50 & 15
Sir give some idea about which type of smps is used for audio amplifier .
Whitch smps use for class AB amplifier and for class D amplifier.
i have no practical experience in audio systems and i never worked on these types of circuits
i will discussed with someone who is dealing with audio power electronics, and it will my pleasure to reply it
please accept my best regards
Sir Aslam alaikum sir mere pas batry charger he meter p 13 volt he magar load dene p voltage Kam hojate ge ab Kya kare mere rahnmae kare , pmw ic 3843 , MOSFET 13 n 60 he lagaya he mene brige short tha risister 2 kharab the , AK 10 oms 2 wat or dosra 10 oms water wat ka sir ab Kya karen
Thanks sir
welcome and special thanks
Brother vcc per 25v 100uf Ka capacitor agar jaldi kharab hota ho to kya keya jaya, 06 month ya 01year life ho to, qk hamaray pass 12v or 05 volt ke power supplies kafi tadad may use horahi hay sub supplies may ye common issue ata hay, kindly es Ka solutions BATA day , ta Kay ye capacitor kharab na ho
Sir I have 230 to 24v powers supply this power is supply medical film printer, but problem is that when I gave the laod it will shut down at that time i check output it shows 24v.. Can you please tell where's the problem.. I have replaced all capacitors.. Thanking you
Sir, I have str power supply board, there 1no pin positive supply, 2pin negative supply via registance. 3pin direct negative. 4pin sync volt. 5no pin feedback. Please describe this power supply.
One thing is not clear. We have a zener diode as reference. In your example you have mentioned that voltage vcc will fluctuate according to the load. In the presence of the zener, how voltage will fluctuate that much.
Please clarify. Thanks
zener is used to provide a reference for optocoupler
when there is no load at output, for example PWM controller is switching at 20% duty cycle.
when we put load at output, it will cause to drop voltage at output terminal, so the zener or adjustable reference TL431 will drop its fixed voltage and upper voltage will applied to the optocoupler.
the dropped voltage will reflect to the SMPS controller will increase its duty cycle, to fulfill the dropped voltage which were decreased due to load effect
i will try to explain it in detail.
Sir ,aap bolte ho Yeh capacitor,Yeh resistance ,Yeh diode ,Yeh pin ,Yeh circuit, hme pta nahi chalta consa kyunke ke aap ne apne laptop ka curser ik dot (.) Rakha hua he use errow kijiye , please
I really appreciate your work in a way of spreadind knowlodge
Sir, how to communicate with you, i want to send a video on whatsapp of 5,12 volt power supply
Us smps me alag se ek card use kiya gaya hai jo 2 wire se connect hai usme ek ic aur mosfet laga hua hai, us smps ko series se star krne pr smps ki light blink kr ri hai sath me series ki bulb bhi blink kr ri hai, usme ek c80m ic diode short tha to use change kr diya hai but ab fluctuation ki problem aa ri hai, i would be thankfull to you plz tell how to resolve thi issue
00962-79-1161084 whatsapp
Same problem ek 36 volt power supply me hai .. 36 v or 12 v chahye to voltage fluctuations ho rha hai or power supply ka light blinking kar rha hai .. sab kar k dekha hai .. ek smd zenor diode burn hua hai uski jga konsa zenor diode lagega bro ? Ap whatsapp no dijye video send karta hu bro
mera whatsapp 00962-79-1161-084
In a smps having 3 output 5v,+12v and -ve 12vdc fitter capacitors in+,-- 12v output circuit blast with out load kindly guide which component is bad or any other reason,78M12 and 24A12 regulators are used please
78M12 and 24A12 regulators are used
the rectifier diode is bad, it is applying ac voltage to the capacitor, so polarized capacitor blasts with ac voltage. or if the voltage rating is less then the supply voltage, or the capacitor is connected in reverse direction.
these are the reasons of the blasting of the capacitor
voltage regulators are rarely involved in this fault
Power supply main se ic se circuit kaise calculate kiya jata hai?
Alag alag topology ke sath kaise calculate kar sakte hai sir?
yes dear i will try to explain very soon
Sir
mere SMPS mein output high voltage a raha hai but feedback circuit ok Ya problem kahan se a Rahi hogi
kitney voltage aa rahey hein
feedback circuit me TL431 ki pin 1 ko check karein
us k voltage divider network ko check karein
00962-79-1161084 mera whatsapp he
Sir,main aur kya kahun aap ko,cricket main sachin ko bhagbaan bolte toh aap electro nics main bhagbaan hai.aap ye bataiye ki dc volt koi transformer kam nehin karta,toh phir relay kaise Kam kar ta hai
Sewing machine Hvp-90 dear sir review
Sir computer Orange light problem per video upload karein.. plz
i have no good experience in CPU faults.
Sirji 60 hz meaning 60000 time switching???? Or 60 time switching🤔🤔🤔🤔🤔
60 means only 60 times in one second
60KHz means 60,000 times in one second
Varana aaj ke is sansaar me koi kisi se bagair matlab ke salam bhi nahi karta

No power on ic replaced still no oscillation ic3845 vcc 8 volt is ok
24Volt se Jada 40Volt Arha hi
Sir fluctation ka bataya kyu hoti ha
please check video number 34, 244 or 259 for fluctuation
Isliye hi tum log piche ho kyonki tum theory par dhyan dete ho practical par dhyan nahi dete ho tumhari is theory se koi bhi suply thik nahi hogi practical par dhyan diya karo koi bhi component ka name nahi liya tumne
Sir Kishi bhi IC Ki equllent Kaise dekhe mujhe bataye 9756567453
very nice sharing
Thank you so much 🙂
Thanks sir
thanks a lot dear, best regards
