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 RUclips 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. 🌻🌻🌻
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...
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 :)
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!
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
Thx for information but i have a question if my output is 300v how to i check then.you have output 3.3v but my power supply outputing 300 volt then how to i test feedback circute
@@HaseebElectronics Sir your explanations are easy to understand please start a series of basic concepts of electronics like lcr circuit, Juel thief with practical.
Behtareen aur zabardast presentation in a very detailed manner, like always. Your presentation is as such as if you are teaching to kids, just to understand them from the basics. Highly appreciated your good work and hard work. Keep it up, plz pin my comment. Thanks.
Thank you very much for kindly and humbly sharing your incredible knowledge. For almost a year following your videos and learning much about circuits. This TL431 optocoupler is fascinating how PWM controller gets it’s feedback. One question though, the power supply injection in this case of 3.3 volts - is this dc or ac? Thanks very much for a reply…. Namaskar…

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.
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.

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

YA U ARE RIGHT I LIKE HIM TOO MUCH
Excellent explanation of the feedback circuit using the TL431 and and a great testing technique.
Bahut achchi tarh se samjhaya
stay blessed always bhai
Very good explain
Beautiful video 👍 watch still watch
Ma sha Allah.
Excellent thanks for sharing this informative video keep sharing❤❤
Just great! Smps feedback circuit explained as simply as possible and testing also. Thanks a lot. 👍 and 🙏.
Assalamu allaikum Bhai jazakaAllah 👍 ap n to pora school khola h Masha Allah 👍 Jo log diploma kr rhy hn un k liay bhetareen h.
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.
Great description of the opto coupler! Thank you! Now I know how this works. I can see you're a big fan of the tl431 regulator.

Nice explanation. Il be nice to see video about smps that regulate voltage and current at same time like those used to charge lithium battery.
