Thanks! Was waiting for an SMPS job from you. What a great explanation! Can't believe how well you can elaborate on live circuits. I understand a lot more about the feedback circuit now. I remember asking you to help me understand that part in a comment on a previous video. Here you respond! Thank you friend. I'm grateful for the effort you're putting. May Allah bless you.
First thing, I appreciate your efforts & the way u explained the Circuit was Excellent. But one thing i felt that, if u could explained or calculated about the of resistor values used at each section, it would be more great helpful bro. Great job bro..
HELLO SIR, LIKE ALWAYS I NEVER MISS ANY OF UR VIDEOS...SIR KINDLY MAKE A VIDEO ON CR6848 VS SG6848 AS I WANT TO REPLACE SG6848 WITH CR6848...PLS PONDER UPON POINTS THAT ARE AN ABSOLUTE NECESSITY WHILE REPLACING IT...REALLY LOOKING FORWARD FOR SUCH INTERESTING AND MEANINGFUL VIDEO...HOPE U MAKE ONE .THANKS AND BEST REGARDS SIR....
Thanks for this video, you were a little fast, which I can't understand, at the optocoupler is what the direction of the current passes in both directions through the diode inside this optocoupler (normally the diode only conducts in one direction)
Hello, nice video ! can you explain where to put the multimeter probes to get the frequency ? can you please show how to measure the voltage at the exit of the SMPS transformer. Thanks
it can be done by disassembling transformer and finding turn/volt ratio, and reduce turns in secondary. and then re-arranging voltage divider network, in TL431 and to remove 39V zener from sense line for PC817 LED path
I have three phone batteries in series about 12 .5 v .the charger open circuit is about 13.2v .it charges normally the batteries but some time it doesnt do it .it charge it about 11.6 v .i have separayed the batteries and with a phone charger i charge it very hood can you explame it
i think the phone batteries have BMS (battery management system) a small PCB inside the battery. at full charge, may be it is stopping the charging or may be the thermal protection is activated in case of over temperature of the battery
You have drawn wrong position of 10k resistor connected across power ground and drive pin as per the pcb layout in your diagram. Actually it's a pulldown resistor and is connected just across the gate and source of the mosfet. Thanks sir.
A.. O. A sir mashallah good work sir apka what app no knsa hai sir main apka subscriber ho sir mjhy apsy ek kam. Sir main 12volt 15amp ki smps banana chahta ho. Jo 12 volt cooler ko chlany ki kam ay gi r usmain short circuit protection bhi bnana hai sir mjhy thank apki help ki zroorat hai. Thank you sir plz mere sath apna contact no share kren

Fabulous work. Great tutorial brother.
Maasha’allaah very nice 👍
Wooow perfect decleration and explanation. thank you so much.
You're most welcome
amazing video 😱I waiting for the next part
Circuit diagram harus teliti banget ini
Excellent explanation
always watch your tutorials always excellent thank you kindly for these videos sir you do a great job explaining keep up the good work

Greetings know everyone
Thanks! I look forward to the next part. Is your line voltage 250 VAC or 230 VAC? Or does it fluctuate?
Very good and useful information sir thanks for sharing this knowledge to us
Plese share Multymeter model no and up loade vedio for explain

السلام عليكم ورحمة الله وبركاته..plz the vcc courant of ic its 22.8 v that very high...can you explain it ...professor....شكرا
No. It is normal vcc. Some ic work upto 35 volt

Hello, nice video ! can you explain where to put the multimeter probes to get the frequency ? can you please show how to measure the voltage at the exit of the SMPS transformer. Thanks
Best regards, i uploaded a video, containing the answer of your question, video number 381, please

How to reduce the voltage - answers on a postcard please. I'm guessing that resistive ladder, and taking out the large zener .
it can be done by disassembling transformer and finding turn/volt ratio, and reduce turns in secondary.
and then re-arranging voltage divider network, in TL431
and to remove 39V zener from sense line for PC817 LED path
I have three phone batteries in series about 12 .5 v .the charger open circuit is about 13.2v .it charges normally the batteries but some time it doesnt do it .it charge it about 11.6 v .i have separayed the batteries and with a phone charger i charge it very hood can you explame it
Excuse me for some mistakes in writing
i think the phone batteries have BMS (battery management system) a small PCB inside the battery. at full charge, may be it is stopping the charging
or may be the thermal protection is activated in case of over temperature of the battery
I consider your explanation useful .
How can calculate the biasing resistor at tl431 and the capacitor value
