Having witnessed several students wire up the bus and driver, only to forget the driver needed to eat as well, I can only say that this is the best explanation I've heard yet! Thank you so much!
I've been following your videos/tutorials for sometime now. I am very grateful for benifitting your videos. Your explainations are very clear and simple. Keep up the good work Sir!. Thank you so much.
It's a wonderful explanation on the biasing circuit of A SMPS with very keen pointing of the operation of driver , thanks Sir for Your great explanations
صباح النور اختي🏆 New guest 🏆 Peace be upon you, my dearest friend. I came to visit you in your beautiful home. I did the homework and hit the bell button, I love watching the whole video. Enjoy beautifully. Thanks my sisters. I will be glad if I see you in my house. Greetings to all dear followers. 🏆🏆
Assalam alaikum sir. Just wanna thank you for all the knowledge you've shared on your channel. I discovered your channel 3days ago, I've been binge watching all your videos and I have really learnt alot. Thank you so much. May Allah reward you abundantly.
salam, Mr.haseeb I watched several videos about the SMPS i found them beneficial. I want to ask about two recurrent matters in SMPS. 1. when the power supply starts with a buzzing sound (i think from coils) and after 5 to 10 seconds it turns off suddenly. 2.if all the multi voltage power supply is working normally but one voltage is missing (6v), when I applied 6v to the output dc capacitor ,it drew high current and I got a voltage drop. It would be great if you could benefit me , especially if you encountered such problem. Regards
New subscriber here. Sir I have an SMPS here with no output that I have been trying to repair for a week now. I replaced the components that i found faulty. I can now read DC voltages (around 290 to 300 VDC) at the input of the transformer but unfortunately it appears that the xformer does not magnetize. it shows zero volt at the secondary side and as well as at the aux winding. Kindly tell me of the possible points that i missed to check. thanks in advance
My Vcc at the the pin 13 of the IC ML4800 is 5V while it should be 14V. Also the voltage between FET D-S is only 308V instead of 420V. Voltage over the power caps are also less than it should be 312V instead of 386V. I ve replaced the IC, the power caps, the switching mosfet. Still the same problem. Can you please help?
Hi. Very pleasant and descriptive. I have a question. Could we have the same IC start without soft start ? Directly from a winding via a rectifier directly to pin 7 ? Did it ever happened to you ? Thank you
Hi. Is there something else that can be used instead of an incandescent lamp in the series circuit to test power supply? I can't find bulbs except led ones in my country. Thanks
hi sir can i replace a transformer with secondary coil of smps like the example with a simple transformer ? or will i have problem because i cannot control the current of output
Great brother very wel explained wel done thank you JazakAllah... Ye Mera bhi sawal tha jiski mujhe samajh nahi arhi thi jo ap behtareen tareeqay se samjha diya.. Bht shukriya Alla ap ko khush rakhay aur apko iska ajar de.. Aameen
I accidentally short circuit the direct secondary terminal of smps transformer and the smps stop working, (checked no fuse blown).. PLEASE LET ME KNOW HOW TO FIX IT....
Good evening sir I just received some igbt from China 40n60A4D but the data sheet showing the diagram that the igbt has no body diodes like mosfets I want to use the igbt in my smps but I need to know if I should use a Shockley diodes across the collector to emitter for safety or it’s ok no to use diodes thank you
Thumbs up done sir how can we determine the correct supply voltage of the vdd capacitor that connect to the auxilliary winding and to the vdd of the controller if its normal or not for different types of smps power supply sir or there is a voltage range value that we can measure sir tnx
How do you decide the value of soft start resistor? I have seen your previous video about making adjustable output voltage by smps. Is it possible to make adjustable voltage and current together? Can we turn smps into home made lab bench power supply with adjustable voltage and current ? If possible please make a video about it so it will be very helpful for beginners like us to learn about electronics. Thanks again for your hard working. Always love your videos and explanation. Keep it up
please check video number 386 yes we can limit the current and adjust the voltage but it need very precised calculations for banch power supply it is better to use a separate voltage and current regulator in output i will try my best to share a compact design for bench power supply
I mean like adjusting Voltage in smps like you did with a potentiometer, can we adjust current with potentiometer? Or by adding a transistor? (or Darlington transistor in the output)
Sir is that auxiliary winding is in the secondary side of the transformers? Sometimes that auxillary winding is in the primary side of the transformer it is correct sir? tnx
in any transformer there is only one winding used as primary other all winding are secondary winding it depends on the user how he uses any circuit if it is used in primary side or secondary side it will remain the same if auxiliary winding is used with primary side or secondary side, it will remain output winding

Very good explained. The rectifying diode of the auxiliary circuit should be schottky type?Thanks
best regards
yes output rectifier must be schottky, Fast rectifier, MBR type
with low forward drop voltage
عالی و بسیار متشکرم در پناه الله موفق باشید
خوش آمدید و تشکر ویژه

çok güzel bir paylaşım olmuşşşşş
Terima kasih telah berbagi skema dan cara memperbaikinya brother
adakah link terbaik untuk saya bisa menemukan tiap skema seperti ini?
thanks a lot dear brother
How does it control a specific maximum current or voltage?
Sir, VCC capacitor is fluctuating. I have changed the 50v 47uF capacitor. Still fluctuating .. where to check please..
Please chech secondary side short circuit components
Something is interrupting the feedback
Sir one more question.
How to check driver ic is working or not with normal multimeter.
please check video number 522
Very nice bhai
welcome dear
clear explanation. can you explain tank circuit in smps
thanks a lot
sure i will explain it soon
Nice video

Good evening sir I just received some igbt from China 40n60A4D but the data sheet showing the diagram that the igbt has no body diodes like mosfets I want to use the igbt in my smps but I need to know if I should use a Shockley diodes across the collector to emitter for safety or it’s ok no to use diodes thank you
datasheetspdf.com/datasheet/40N60A4D.html
in this datasheet it is showing datasheet
40n60A4 is without body diode
40n60A4D is with diode
@@HaseebElectronics no sir not that type hgtg40n60a4d sorry for not adding the laters
40N60A4D is generic number
prefix letters are never marked on the components
check in the datasheet in
ordering information section
the marking on body and real part number are mentioned in that section
Mashallah all teach best
thanks a lot
best wishes and special thanks
👍👍👍
Thumbs up done sir how can we determine the correct supply voltage of the vdd capacitor that connect to the auxilliary winding and to the vdd of the controller if its normal or not for different types of smps power supply sir or there is a voltage range value that we can measure sir tnx
وعليكم السلام ورحمة الله وبركاته
thanks a lot dear brother
Thanks.
How do you decide the value of soft start resistor?

Can we turn smps into home made lab bench power supply with adjustable voltage and current ? If possible please make a video about it so it will be very helpful for beginners like us to learn about electronics. Thanks again for your hard working. Always love your videos and explanation. Keep it up
Oh found your video ( video number 386) about calculation of startup resistor. Thanks again
please check video number 386
yes we can limit the current and adjust the voltage
but it need very precised calculations
for banch power supply it is better to use a separate voltage and current regulator in output
i will try my best to share a compact design for bench power supply
wow that is great. i also sent the same video number for you
I mean like adjusting Voltage in smps like you did with a potentiometer, can we adjust current with potentiometer? Or by adding a transistor? (or Darlington transistor in the output)
Sir is that auxiliary winding is in the secondary side of the transformers? Sometimes that auxillary winding is in the primary side of the transformer it is correct sir? tnx
in any transformer there is only one winding used as primary
other all winding are secondary winding
it depends on the user how he uses any circuit
if it is used in primary side or secondary side it will remain the same
if auxiliary winding is used with primary side or secondary side, it will remain output winding
Bahut acche.sir Mera ek question hai feedback ke resistor calculation pai ek video banvo na
وعلیکم السلام good information
thanks a lot
