really i am sorry to listen that mein ne aap ki saag wali video per five gift kiey the, jo aaj wapis kr liey hein. zaroorat ho to phir btaa dena mein kabhi kisi se wapis nahi leta lekin aap se is liey wapis kiey, ta k aap ko yaqeen ho sakey
Dear brother 1.What if the tester glows at any point on the circuit board .What could be the reason ? 2.What is the best book for learning designing electronic circuits? Thanks
1. if the tester is glowing in all the circuit, that means that there is leakage in isolation or it may have floating ground 2. designing is deep sea, first it needs to do complete design engineering in the specific category
the ground is very annoying specially when it is touched slightly will give you big shocked so as always i always remove the safety capacitor from primary ground and secondary ground and viola no more annoying shock ground from live. done this in all my smps no effect whatsoever its just a useless filter haha why they put that annoying ground anyways, so useless no benefit at all, prove me wrong pls
you are right. this capacitor is most effective when this power supply is being operated in high electromagnetic radiation area and it is driving some sensitive load. in this situation it will pass the common mode noises to the load and the load may damage, especially in case of microcontrollers, it causes to create false actions by the MCU or sometime it damages the circuit as well. in routine, the common mode noises can e ignored, but it is better to remove common mode noises
Sir what is the use of class y capacitor between primary and secondary side of SMPS? As primary side and secondary side ground are already connected by metallic chasis!
I have a 12 volts 2 Ampere set top box adapter whose output jack when touched with line tester the tester lamp glowing although I don't get electric shock on touching with hand. Why so? How to resolve it?
I have two old 12 Volt 2 Ampere adapters & both outputs have line tester glowing but I purchased a new 12 Volt adapter & there too the line tester glowing when power on & touching with it. Why this is happening in new one also?
At 4:47, you said if the cap goes short, actually Y caps go open when they fail which is unlikely to happen, also when the ground is floating you can measure 120v AC difference between your body and any metal of the SMP, even the usb ports of the PC and is what is causing the shock without earthing, great video keep going :).
Salam M Haseeb, thanks for the video. I have the approx same 12v20A psu running with a 3842 and mosfet, 16v is present at VCC but no signal at the drive pin. The IC has been changed but still the same issue... any idea where to look at ? thanks.
Haseeb sir assalaam walekum I am requesting you that how can we repair the inverter pcb board which is coming in refrigerator washing machine, And tell us in detail about what is UVW in inverter technology
As Smps is a switching device it will always make noice. So earth is compulsory as per your description. I tested on mobile chargers as it has no earth input. It has no such issue. I checked so many smps like this most of them glows tester except mobile chargers. So is it ok. You teached purpose of xy capasitor and its usage thanks for a big experience.
Thanks, your explanation is excellent. Regarding the latest DC power supply, is it fair to say that this is a poor electronic design? See you next in the video
wow that is super contrast in engineering. I lived your attraction towards electronics. wish you best of luck dear respected Engineer I completed my Engineering in 1990 and now I am head of my department. and I established a small workbench in office to teach my young technicians and engineers meanwhile I am sharing on social media so it might be helpful for someone
Show fan heater fuse changing & trouble shooting more videos for females please. I have three fan heaters and all not switching on & central heating gone kaput. 🙄
Lk 6 Brother 👍👍👍
Way of explaining things are always so simple that every one can easily understand.
Good instructor
Sir, I am fall in love with your explanation.....
Now , I start to understand how to analyse circuit, and about testing....
Thank you so much sir
You are most welcome
best regards and special thanks
👌👌👌👍
Aslamoalikum bhai...you know .where is your gifts... you says i have given gifted.but nooooo...... remember☺️
Best wishes.stay bless
really i am sorry to listen that

What you provide us is always great and distinguished

Video recording sound not too clear.
Yes audio quality of only this video is distorted,hope next video will be ok
73 lk dear💕💕💕💕 beautiful share Bhai
if chassis connect to metal point of earth then it causes to shock the person who touch the smps.
Masha Allah Bhai Masha Allah Gorgeous Aarti Video Aarti
Bro plz explain about volt wat ampere
Mashallah stay connected
Jazaak Allah khair
aap ki latest video k comments off hein. please check it
Walikum Salaam Janab Bhai Saab
I like your video Thanks.
أحلا لايك و أحلا مشاهده

Very interested video
Like Video # 47
Nice info 👍👍
Good info bro
Very nice
Nice
Tq would like to learn more you,very good explanation
Thanks and welcome

Superb video 👍👍
Sir, Pls explain about resistor capacitor combination ceiling fan regulator... (noiseless ceiling fan regulator)
Very good

I am new to your youtube. Could you discuss the power supply of a LED TV. Thank you , I like your site, I learned a lot.

Thank you again for your help,? How do you test a optocoupler can I b the reason for no this play on a inverter A/C unit
Thanks, your explanation is excellent. Regarding the latest DC power supply, is it fair to say that this is a poor electronic design?
See you next in the video
Nice 👍
Haseeb Bhai hmaisha ki trha wonderful video or hmaisha ki trha sar sy fly kr gye 😜
Excellent thanks for sharing this video
Informative vedeo. Thank u so much
wow really informative video
Very informative!
it is my pleasure
Thank you my friend. What is your background?
welcome dear
i am just a tiny avionics engineer
@@HaseebElectronics I'm a mechanical engineer but micro electronic is my hobby
