I wanna thank you speaking in English for this informative video which is hard to come by these days that alone sir has earned you a like and subscribe button.
best regards my video are also available in urdu language for my pakistani brother on my urdu channel at (haseeb electronics urdu) my all these videos are shared in urdu language for pakistani and indian viewers
Hi sir, you made my day. wonderful explanation and i repaired an SMPS, the switching IC number scraped by the SMPS producer, their intention was not to repair it., so that i could not find the IC number and there is no IC switching , and found that the IC fault not switching and found IC number by your diagrammatic explanation. thanks a lot. almighty may bless you.

Asslamualekum Haseeb, l did my electronics in mid 70,s when smp,s were just introduced, all the theory and no practice. I enjoy your programmes and have come back into electronics as a hobbyist and thoroughly enjoy your programmes, thank you for sharing, and please keep the good work up, this is truly sadqai jaareah.
Engr. Haseeb good afternoon from here am a subscriber of your channel, your videos on SMPS power supply had been of great information and I was able to fix my Laptop and phone chargers thanks amilliin.
Mr. Haseeb, all of your videos are excellent. I really like how you take the time to cover all bases of the component you're testing. I have learned so much from your teaching style and I would encourage you not to change anything the way you explain things. Is possible in the near future you can do a video on to read a circuit board, so I can better understand what and how to test components on a circuit board! Thanks Bennie G
Hi .Mr Haseeb can you do a video on repairing a 1.5kw servo drive,,,voltages test and also a stepper drive,,,pliz explain how to test their igbts it will be informative and educative no one in RUclips has done it well like you do ..we love your work
Buenas noches , que videos también Buenos y bien explicados , apesar de la barrera del idioma las explicaciones se entienden perfecta mente los felicito , sigan asi
Realy Haseeb bhai in this world where every person see thier interest Even in a small efforts he does, you are doing a great charity for those who are realy wants to learn things but unable to do any course. You are a gentelman

Hi friend thanks for another informative video, the more I watch this type of videos the more I learn thank you. What is the model number of your multimeter
Sir G aapke har eak videos perfect knowledgeable rahate hai , aisehi videos banate rahiye hamareliye 🙏 1 request hai aap se ki smps me hot section k parts nahi mil rahe to module lagake kaise Kam chala sakte hai ? Aur uskeliye primary k kun se parts aur kyu nikalna jaruri hai wo points samza dijiye please 🙏 primary section ke parts available nahi hote to external smps lagake kaise Kam chala sakte hai 🙏🙏🙏
most valuable information, Sir. Please, single phase preventer (auto switch) ka circuit detail me explain karenge to bahut meherbani hogi. Sir🙏🙏 with transformer and without transformer ka circuit ke sath hua to bahut khub rahega 🙏🙏
Thanks for beautiful description. One of my question is can we give 12 v DC from outside to ic vcc pin without connecting to ac 220 v for checking ic. If ic is working it will give reference voltage and out put of gate otherwise not.
Thank you, Professor Haseeb. Great video. I have a question. What is the reason or the defect in hearing the sound of tick tick tick in the transformer? Although all the parts in the high-voltage phase are intact. thank you
best regards and lovely thanks 1. if any winding have bad soldering joint with mounting pins of bobbin (remove the transformer and re-solder the winding ends with the bobbin pins) 2. if switching frequency jumps (check the frequency ) 3. sometime the ferrite core bonding becomes loos and produces the gap between outer leg.(in this case disassemble transformer and apply glue to the legs & sims if it is gaped core) 4. if winding becomes loos (pour varnish) 5. in some situations it may be unexpected sudden spikes from load (in case of capacitor internal sparking)
Thanks for the wonderful video, very exhaustive. I have a question: there is a rule, a formula, between main capacitor voltage and D-S modfet voltage? Thank you
best regards and special thanks yes there are may calculations for dc capacitor. witching at different duty cycles, and in result the voltage applied to primary and in off period the stress in this video i compared the voltage stress in dc voltage range we can check it with dc range much safely than the ac range
Very very interesting ! i'm à new subscriber from France. Can you tell me please...i don't understand, on Mosfet Q1, what is the role of C9+R9+D3 ???? Best regards.
Sir It's a great video When smps is working, Difference of voltage on main /bulk capacitor and in mosfet drain and source is it same? (approx 25volts in this video) for all smps circuits?
it depends on the rcd snubber's efficiency. this difference may be 5V to double value of the capacitor's voltage i mean if DC capacitor 300VDC, then the mosfet drain to source may be 305 to 600VDC

Sir It's a great video
When smps is working, Difference of voltage on main /bulk capacitor and in mosfet drain and source is it same? (approx 25volts in this video) for all smps circuits?
it depends on the rcd snubber's efficiency. this difference may be 5V to double value of the capacitor's voltage
i mean if DC capacitor 300VDC, then the mosfet drain to source may be 305 to 600VDC
