On TH-cam there are so many videos on smps and chargers but your way of teaching is so unique , best , easy to understand. Your knowledge sharing is like a gift of God to us which help us during interviews , exams etc.thanks a lot for sharing valuable knowledge.
A very good video with deeply explanation ❤
best regards
Paráda nemá chybu tvoje vysvětlení spínaného zdroje včetně schématu velmi dobrá práce. 👍
s pozdravem a zvláštním poděkováním
Thanks.much love from uganda
mot welcome
thanks sir ji....
وعليكم السلام ورحمة الله وبركاته
Thanks for the knowledge and the video and the fact you are speaking English so I could follow.
Very good and useful information sir thanks for sharing this knowledge to us and waiting for next part
best regards
sure its next part is coming very soon
Thanks for your easy to understand explanations and have a great day.
You are welcome!
Best and easy to understand explanation...thanks brother for sharing knowledge ❤
Thanks and welcome
Merci beaucoup. I subscribe🥰
cordialement.
احسنت ستاذ شكرا الك الي نشر العلم نود منك المزيد في الشرح والتوضيح
Fantastic!
Many thanks!
Its a good job. Good to have the diagram. Good day 👍😉
Thanks and wait for your next video😎
Belle vidéo! Bravo👍
Hello thanks for all those interesting lessons. I have two questions... FIRST, If we have current sensor on pin 4 why we need voltage divider for pin number 3? Second does chargers switching with out load? Thank you
Emeğinize sağlık efendim. Hayırlı ve sağlıklı günler dilerim.
Thanks a lot for sharing your precious knowledge and experience sir
Thanks and welcome
Very very informative vedeo . So many ics are in Chinese circuits which has no nos. Or datasheet, which is big problem to repair the circuit. This is very very helpful vedeo for this. Pls share the proper calculation of output capacitor mathod Or formula also. God bless you.
best regards and special thanks
sure i will arrange to share calculation process for output capacitor
Good information thanks sir ji🙏
Excellent thanks for sharing
Excellent sir
Plz make video on mobile fast charger
👌👌👌👍
Please make video on printer formatter board
You are genius
best regards
آلله يرحم الوالدين ❤❤❤
Please tell me when we change samsung led tv orignal tv backlight ,we use copyback lights not orignal then the picture of led tv good or not sry for my English 😀
for a long life solution
it is best. when LED backlight is off.
replace all LED strip at same time (even one strip is off, bit replace all of strips together)
even if you replace the locally available strips.
hi. I don't understand what is this winding in the left of paper and what it done ????
Nice 👍
Kya aap neckband circuit ki ok information de skte hai kya
Dear Sir I have watch your videos it was so good in SMPS repair
I have adapter in PWM IC in VCC voltage low power came instead of 18V or 21V 7V come in VCC pin can you guide
❤❤
Sir last me jo explanation ki hy, us me confusion hy, output wali secondary windings py load se voltage drop hon gy, is drop ki wja se primary side ki secondary winding me voltage me reverse emf ki wja se ezafa kese hoa hy?samaj me baat nhi i hy sir,
I have a question Hasseb, my phone charger has a charging capacity of 120 watts from the factory, and I tried another charger from a well-known company with a capacity of 120 watts, but the 120w fast charging did not appear on the screen of my phone. What is the reason? I gained a lot from you about analyzing the power supply circuits, but is there encryption to force us use the factory charger.
i hope someday you could explaining about fast charging output concept and example actually 😊😊
thank
Why the out put diodes are off different (ss54 and ss34)
Thanks sir❤
Most welcome
Sir, you mention that the class Y capacitor is connected between primary and secondary ground. (between the primary and secondary coils?)
It seems to me that this capacitor is between the auxillary winding ground and the primary side of the transformer (its ground) .... is that correct ?
Very interesting how the aux coil can be used for voltage sense. Thank you for sharing.
How can you add variable voltage output?
in input???
@@HaseebElectronics Sorry no. On the output.
in offline switching power supply, the output voltage are approximately live in regulated window.
as in offline switching regulator, it takes ratio-based voltage values from auxiliary winding
and uses leading edge blanking method by means of current sense resistor
so
in this it is difficult to take variable voltage from this type of converter
while in optocoupler based feedback circuits it is easy to take variable voltage
Could u please do make a circuit for variable battery charger.. 12v ,24v - 72v lithium batteries, which have different cut off voltages. . so need a potentiometer for cut off voltage set ., and circuit could support upto 20 ampere current. . current adjuster can adjust from boost convertor input supply .. I am finding everywhere but not getting anywhere. Plz do make it..
What is the name of the printed fuse? Allah bless you
DP1801B, MD1800/01. OB2535 is similar as well.
if we can not know the datasheet of modele this ic & ic is good & can know the pwm of ic can selsect another ic have same pwm thanhs friend
why are there usually 2 diodes in parallel at the output ?
For faster pass maybe
To share the current spikes.
Ap pakistan airforce sy retd hain na 😅
Why the out put diodes different numbers
buscando a ese ic lo mas parecido es el ic OB2513x la diferencia seria FB del pin 2 y en five-v es el pin 3
This is UC3842
Hi sir, why is the capacitor rating 10uF 400V, shouldn't it be 130uF?
Hey! Not to sound rude but on what basis are you saying that it should be 130u? I'm just starting out on electronics but I'm having problems figuring out values of the component specially charge of the capacitor. Kinda curious on why you said that value.
