- Watch this Video in Urdu Hindi • #76 How to Test Feedb...
in this video i discussed whatvis 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
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
Excellent thanks for sharing this informative video keep sharing❤❤
Very interesting video tutorial🙏🙏
There cannot be easier explanation than this. It's great video on SMPS feedback function. Thanks a lot.
This video just helped me verify that the feedback circuit in my audio receiver SMPS works! Thank you! :)
best regards 💕
Bahut achchi tarh se samjhaya
stay blessed always bhai
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. 🌻🌻🌻
YA U ARE RIGHT I LIKE HIM TOO MUCH
Wow So Great Sharing
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.
best regards
it is my pleasure that my efforts are useful for my viewers
@@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
A great video. I enjoyed the simplicity of your discussion. Thank you for sharing....many blessings my friend!
best regards
Very good explain
Beautiful video 👍 watch still watch
Ma sha Allah.
تبارك الله يعطيك العافية 👍
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🎉🎉🎉

You are very welcome
Assalamu allaikum Bhai jazakaAllah 👍 ap n to pora school khola h Masha Allah 👍 Jo log diploma kr rhy hn un k liay bhetareen h.
Mashallaha very useful tutorial. Thank you for sharing. very nicely explained. 🌻🌻🌻
Great sharing well-done .
Always very good sharing 👍
Just great! Smps feedback circuit explained as simply as possible and testing also. Thanks a lot. 👍 and 🙏.
Wonderful work full watch
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.
best regards and special thanks
Very nice sharing, stay blessed.
amazing sharing with big lk
Thanks good explanation.younes from Morocco jazaka ellaho akhi Karim
very interesting haseeb thank you
You are most welcome
Awesome. Sending you love & support from Australia 🇦🇺❤️
excellent explanation, very good
it is my pleasure
Finally i found a great youtube channel for electronic 🙏🙏🙏
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 :)
Спасиб, за знания,Друг! Прекрасный урок, очень полезный!!
Masha Allah brother very informative about feedback circuit buhat khoub
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!
please send the diagram to my whatsapp 00962-79-1161084 or gmail id ashraf4ta4
Thank god, someone who speaks english. Good video, thank u
it is my pleasure. stay blessed
