Last time I fixed a power supply with an issue in feedback circuit it took me several hours, but using your method will make it so easy. Thank you so much.
@@HaseebElectronics sir you the best. Nowadays on UA-cam when am looking for electronics video's if i find your video it means have understand even before watching it. Easy explain but very informative. God bless you sir
Very informative and easy to understand explanation on how voltage is regulated in SMPS depending on the resistance of opto coupler transistor which is connected to the controller circuit.
yes dear, it is close loop feedback circuit, this regulation is done on CTR (current transfer ratio) method which is a ratio between the collector current and LED forward current
Do not find such tutorial in1982 when I was a student of electronics. any how great tutorial. I hope many many students will be the benefisher from such explained tutorial. 🌻🌻🌻
Really happy with subscribing to your channel. You are simply a real expert in both electronics and explanation. Grateful to all the information you provide :)
Salam M.Haseeb, my special and kind regards for this very clear video. I cannot wait to apply this to many silent PSU to see where is the problem. May God bless you for all that sharing. I can watch your videos for hours...
Thank you for your videos. They are extremely helpful!! I have an interesting circuit that I am trying to diagnose. The input side of the optical "resister" Is controlled by more than one component. One terminal has the resistor and the zenor diode, the other terminal has a transistor. Both of these are connected to the negative side of what I'll call the "emitter" side of the optical resistor. Would you mind explaining how this works? I can send you a copy of the schematic. This is in another switch mode power supply. Again, thanks so much for putting your time and effort into making these easy to understand videos! Much appreciated!
@@HaseebElectronics Sir your explanations are easy to understand please start a series of basic concepts of electronics like lcr circuit, Juel thief with practical.
HI, when regulating the output of a power inverter do i have to directly connect the optocoupler and the tl431 zener diode to the output voltage of 220vac through the limiting resistor and the resister network connected to the tl431?
yes you can use voltage divider resistor network to provide reference voltage to the pc817 and provide offest using some zener regulator in series. set the forward current very carefully to set proper feedback
No other You Tuber can explain so deep like you,today my concept regarding feed back is totally cleared. special thanks from the bottom of my heart.
@@HaseebElectronics U ARE DIFFERENT FROM OTHERS U ARE MY BEST
There cannot be easier explanation than this. It's great video on SMPS feedback function. Thanks a lot.

Thank you so much.

This video just helped me verify that the feedback circuit in my audio receiver SMPS works! Thank you! :)

Finally i found a great youtube channel for electronic 🙏🙏🙏
When ever I am trying to search my doubts in you tube, your chennal is in the top of the list. Proud to be a subscriber🎉🎉🎉
wow it is really a great pleasure for me
@@HaseebElectronics thank you sir.
The only youtube channel that I actually can learn something. Thank you.
it is my pleasure
Very interesting video tutorial🙏🙏
Excellent explanation of the feedback circuit using the TL431 and and a great testing technique.
Just great! Smps feedback circuit explained as simply as possible and testing also. Thanks a lot. 👍 and 🙏.
Masha Allah brother very informative about feedback circuit buhat khoub
Wow So Great Sharing
Amazing Tutorial as Always
