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!
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.
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. 🏆🏆
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
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?
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
In my case. Vcc winding is not generating any voltage. But in continuity mode, its beeping. What can i do. Other components are ok. But smps restarting as you said. Output voltage is fluctuating in 9-10v ( modified for 10v). What can i do now.
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)
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
Sir your video support me for repearing thanks for such simple language teaching sir please make video faulty electrolyte capacitor in SMPS what is the effect on SMPS cct
Assalamu'alaikum Sir.. what's different between power Schottky rectifier STPS20120CT with MOS Barrier Schottky rectifier V30120C? I hope you will answer, thx before, May Allah make it easy for you and always healthy 🤲🏻🙏🏻👍🏻
STPS20S120 is from ST microelectronics for 20 amp 120V with 0.7 volt fprward voltage drop V30120C is from vishay semiconductor having 30 Amp 120V with 0.68V forward voltage so V30120 is better than STPS20S120
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
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
yes we are on the same boat so far. still i am focusing to clear everything for my viewers abut smps. it is my opinion that if we understand SMPS, above 80% electronics faults are behind these section

yes output rectifier must be schottky, Fast rectifier, MBR type
with low forward drop voltage

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)

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
New come Idhar bhi nazar

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
Great effort sir
Nice explanation.
Could you please explain UC3854DW PFC controller and PWM.
Thanks for valuable information, Sir. Please, single phase preventer (auto switch) ka circuit detail me explain kijiy.
unluckily i don't have its circuit diagram or SPP with me
i will try to find some SPP and will explain it positively
i noted it
Thanks Sir
We are on the same boat for long.
Thanks
yes we are on the same boat so far. still i am focusing to clear everything for my viewers abut smps. it is my opinion that if we understand SMPS, above 80% electronics faults are behind these section
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
Bahut acche.sir Mera ek question hai feedback ke resistor calculation pai ek video banvo na
How does it control a specific maximum current or voltage?
