in this video i discussed in urdu hindi what is feedback circuit in switch mode power supply smps. how to test feedback circuit in switching mode power supply.
the optocoupler is connected to positive source through a current limiting resistor and the cathode of optocoupler is connected to adjustable zener regulator which provides offset voltage to the optocoupler upon getting the reference level at its pin 1 through voltage divider resistor set.
so the Ripples in output high line are transferred to the pwm through optopcoupler by means of varying light in the optopcoupler due to the Ripples in Output. it causes the output transistor junction resistance to vary, this varying resistance is fed to feedback pin of pwm controller. which utilitizes it to adjust pulse width duty cycle - วิทยาศาสตร์และเทคโนโลยี

Salam Mr Haseeb...I am your regular viewer, not on SMPS, but all of H.E videos, Pl don't get shaky about length of videos, most of your viewers get what they want and I am one of them. Having over 30 yrs of experience in maintenance in PK & Ca, I still find yr vid extreme helpful to stay fit and to cover my job. I am inspired by yr videos and recovered two power tools battery chargers. Among many of useless u-tubers, H.E is blessing to the guys who spend their time on UTUBE in constructive task. Pl avoid any critism and keep yr awesome work....Regards
Arif Akhter..Canada.
i am thankful for your valuable feedback. stay blessed

Thanks a lot for such nice explanation sirji. Actually me kuchh din se aap ka channel both English and urdu dekh raha hoon...aaj maan kia ki kuchh baat aap se share karoon. Aap really ek nice teacher ho wo isliye ki aap is profession ko like karte ho aur aap achha knowledge rakhte ho iske bare me aur saab se baadi baat aap share karte ho jo ek sachha guru hi kar sakta hai. Me professionally MD Pediatrics hoon jo din bhar bachhon ki beech gujarta hoon...jab bhi time milta hai aap ka channel dekhta hoon..kaab khatam ho jata hai pata hi nahi chalta..apne MBBS ki class ka yaad dila deta hai. Mujhe saab technical chese me interest hai..automobiles, plumbing, electrical,electronics,gardening, cooking etc aur saab khud thik karta hoon. Class 8th me pehli baar soldering iron se pehchan hua tha in the yr 1987 tab radio aur tape recorder ka operation karta tha..kuchh thik hota tha kuchh nahi 😄 phir medica line me ghusne ke baad wo chhut gaya tha...par electronics me khas ruchi hone se online class join karke..led lcd circuit ke bare me malumat kia. Abhi solar inverter 3kv k uper kaam kar raha hoon....isi silsile me apka 3kw bala chhota solar inverter dekha par details samajh nahi paya.. Me 3kw mppt charge controller bala inverter pe kaam kar raha hoon 3525 ic ke paas ka a1020 aur c2655 baar bar short ho ja raha hai line dete hi abhi dead hai.. sab mosfet,igbt ok hai .Kuchh guide kijiye to bahut meherbani hogi. Bahut lamba comment likha hoon padhlijiye ga. Thanks a lot.
Assalam.o.alaikum sir .sir g ap ki video bhot kamal ki hoti ha .bhot asan tarika se ap sikhaty .Allah pak ap ko salamt rakhy .hamari duaa hamysha ap k sath ha.
Sir Jazak Allah you explain things at a fundamental level, i have learned electronics in modern Physics
Sir g no doubt ke vedio baaz aoqat lambi hu jati hy,liken jo sikhne ka shoqin hu wo phr bith ke dikhta hay,app bohat efforts karte hy sikhane ke lye.i must say your a good teacher ,jo apne students ke ungli pakar ke aik aik cheez samjhte hy kabi real objects se kabi proverbs se to kabi hansi mazaq mai.Allah app ko jazye khir de ke app itna qeemati waqat de ke apni experiance share karte hy.jaza ka Allah.khush rahe abad rahe.
best regards my dear. special thanks
