Without a doubt really really the best explanation ever heard. Such a pleasure to listen to someone with that much zeal and enthusiasm. You make learning electronics so easy and pleasurable. You are a blessing and many blessings on you sir!
best regards and special thanks for your valuable words
Please explain me why use of transformer in electronic is less in recently please
Best explanation. I love to see your vidios . 👍🏾
A note to all those reading this. Not so long ago TH-cam wasn't there. We had to rely mostly on our lecturer and ourselves. Even books were a luxury. So take advantage of this and make the most of it. A special thank to Mr Haseeb for sparing some of his time.
best regards and special thanks
you are right that this expansion of electronic media made easy to access knowledge, otherwise we were bound upto the lectures in class room and limited practical in lab, books and notes
Very nice information in this video. i liked it. everything specially circuit tracing is explained perfectly. special thanks to Haseeb Electronics Chowk Azam for adding such valuable video to TH-cam viewers. special thanks
Very nice information in this video, thanks u very much sir !
You are a real master of convincing the listener mind in A to Z level. Thank you sir👌👌
Wow, thanks for a beautiful comment
I am so proud of after watching your video that there are men like you. May Allah gives you the best of everything.
learned a lot from this i didnt know before . just upgraded my skillset with this tutorial.thanks a lot
Sir I am from india. First time i have found a best teacher. Thank you so much sir
all of his videos are good and complete explanation,very useful for every person who are willing to learn,if possible try not skip adds for the benefits of his willingness to help others,the truth is I'm so bless of his videos, so because of that I did not skip adds as a rewards for his goodness, kind and patience to teach others
So much engineering into it if you was in boxes and motherboard all over thank you so much for the sharing we are absolutely hoisting you’re from England
One of the more complete descriptions of power supply design fundamentals. Thank you
You are welcome!
best regards
Excellent explanation. Much clearer than others I have watched. I restore vintage computers, and have a handful of dead PSU's. This makes it much clearer what I'm looking for instead of randomly probing around the board. Incidentally, I have an old Olivetti PC6300 PSU that has a Gammatron T366 transformer(?) and an MPX-A-100 relay that perhaps serves in place of the optocoupler? It does seem to fit your model, because it and the Gammatron appear to isolate the input from the output. I'm just now making my way onto the output side where I suspect the issue lies. Again, excellent explanation friend. Thanks for TH-cam'ing!
So...I know it takes time to make these video's. And the individuals who take this time, which is a un-renewable portion of life, are either wanting to share their knowledge for the hope of bettering this society or are doing it for money...regardless if the information is correct or not.
Or maybe they just want to show off.
After years of looking at these circuit boards and trying to make sense of the process, this video breaks the SMPS down into sections and shows what is happening in each.
Another chunk of knowledge added to my library. Thank you sir.
I typically exit videos when the commentator has a heavy accent. It is difficult for me to follow.
Has something to do with the number of vowels and stress points and... I have researched it some and it gets complicated.
I here you relaying much information and in making it simpler for us commoners to follow you seem to speed up your explanation.
I may be wrong.
What I am saying/suggesting/asking is...to take more breaths so I, and possibly others, have that time, (precious resource) to comprehend more fully.
Doing my best to comment without insulting.
Much information out there...hard for me to understand and follow along.
Thanks again...sincerely!
"...has a heavy accent..." I related to it! Both, in my native tongue or in English BUT, I have to be wise enough that this world is bigger than I think it is, and language barriers are softened when ppl made their BEST to communicate as they can. For instances, in Spanish, I can say we all write the same, but, when PuertoRicans or Dominicans speak, I want to run away.
He has a wonderful voice and I always understand him perfectly. And it’s really soothing to listen to him.
He speaks perfectly
But I still appreciate whoever did the English subtitles because sometimes I also like to read along… Even when listening to American accents… It helps my brain if I can read it also. So big props and thank you to whoever did the subtitles and took the time.
best regards and special thanks
it is my pleasure
i will suggest to check video number 592 for detailed SMPS concept
please accept my best regards

Please you are the best teacher with all theory and practical skills may Allah bless you my best teacher thanks
Good job my friend
great content. very clear. other video are great too. it demystifies the SMPS
I was afraid by these power supply and now it seems so clear. I have few ones in the junk box it will be a good starting point for me (I will use then with an isolation transformer and make some experience has described here.) this is definitively the best SMPS training on TH-cam.
nice sharing dear bro keep it up 👍 👍
what a blessing to have such a real teacher. Bless u Sir.
Haseeb , you explain the procedure's very well. I am trying to fix my control board from a microwave with a stuck exhaust fan issue and hopefully by watching your videos I will succeed. Thank you kindly

this is a masterclass : ) thank you very much!
Thanks Soo much for this, is the best tutorial I have ever seen about power. And is very helpful
You're very welcome!
I ma from sri Lanka.I have less knowledge of English but I understood your explanation.I learned a lot.thank you.
You are welcome
May Almighty ALLAH reward alot for building our skills in electronics
it is my pleasure
Thank you for this wonderful walkthrough, very helpful.
Haseeb ! Thanks So much ! for all your great SMPS videos....I am currently attempting to repair two SMNPs and after watching your videos, I actually have a pretty good understanding of how to trouble shoot SMPS issues, rather than just changing out every electrolytic capacitor and HOPING that fixed the problem.... I was up half the night last night watching your videos, and will probably need to re-watch them a few times so I really grasp everything you show us..... Can't we just come up with a way to direct download the knowledge from your brain to ours ! :-) EXCELLENT STUFF ! Thanks Again ! Rick
wish you best of luck
please check video number 528. in that video i tried to cover all possible problems in any switc mode power supply

Well explanation on how to repair. I used to work also in electronic service center before. Tnx for sharing
Valuable Video to understand function and Practical
Very useful and practical video sir.
I will request to make a video series on design calculation for important components of SMPS with practical examples.
Factors that consider in selecting the right components.
I like the way you explain in this old video, old is gold! I learned alot from this.video. I hope you make the same explanation from a more complicated industrial smps like siemens SITOP, there is no component marking, no clear traces and have a big difference than these types, i hope if i can send you one but i cannot. Much appreciated
Thanks!
excellent class on basic SMPS work very good
Very thanks ur wonderful classes it's very useful to beginners in electronic.god bless you
Thank you. Your explanations and videos are the Best!
Great video watched completely, like very much explanation of function of optocoupler in feedback circuit and how it monitors processor voltage, but it will shut down whole output by shutting down vco/pwm circuitry, easy to understand and apply, thank you.
VERY NICE AND USEFUL VIDEO. THANKS FOR SHARING SUCH TECHNICAL VIDEO
