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 . 👍🏾
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 !
This is the best explanation I've found after looking at many. Thank you! Excellent video explanation.
I agree!
I also agree
Nice and clear explanation sir.....
best regards
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
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
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
Good job my friend

زبردست معلومات ہیں شکریہ
thanks a lot
Thank you Mr. Haseeb Jan, You are a real master of convincing the listener mind in A to Z level. Thank you sir👌👌
You are most welcome
Thank you, very clear and helpful explanation. Greatly appreciated!
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!
Really love watching lessons provided by you . Regards
thanks a lot
Sir your videos are so interesting and satisfying. Thank u alot for the knowledge you are providing through your channel. Thank uu .god bless u ❤❤..

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!
Million thanks to you Sir
It's clearly explained plz. Share more videos mostly in all about smd.
@@HaseebElectronics your most welcome Sir. That's why I never escape the adds,🤩
Best video on smps I've come across so far. Very clear and understandable
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!
Very clearly explained sir.... Thank you sir
You are welcome
When some body it self know what he sey and what he teach every body can learn.exellent my brother
Yes i hav
I wil send you
و من الله توفیق

You are welcome
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
Thank you for your explanation, it is really helpful.

hello my friend the video is very useful, new knowledge enhanced are very useful my friend, greetings from indonesia 🇮🇩🇮🇩greetings always successful 🤝🤝🤝🤝🤝🙏🙏🙏
Very clear explanations
Thanks,God bless you.
You are welcome
When he says at the beginning…. That all of those circuit boards are the same only arranged differently but with all the same parts.
Kind of makes me think of Legos. There are only so many different types of Lego pieces…. but there are thousands of different ways to put them together
best regards
all switch mode power supplies are almost similar
their design topologies and designs are different, due to the power requirements and design geomateries
otherwise the working concept remains approximately the same
Simply woow you are a good tutor sir may God bless you 🙏 for your generosity ❤️❤️❤️❤️ your teachings are very clear and precise with examples to understand each point individually and even shows the different scenarios of components in use makes everything so clear. Just wanna say thank you and may God bless you for your good work........ I admire your videos and just wanna say hi from Sri Lanka......
