In general if you see a feedback through an optocoupler and an TL431 with some resistors around and a cap... It is a voltage controlled (constant voltage output). Maybe it's the subject of the next video 😊
So, I'll be honest. I have not see the change of the DuCy on the high coltage side on the oscilloscope. The signal looked weird af too. A crazy oscillation instead of a square. This lesson was kinda confusing to me. Although in general I do believe to understand the concept. But what I don't understand, is how I would limit the current by that technique. Usually, I would read the voltage on the R between S and GND. Good. The voltage drop on that R is what opens the FET that shorts out the DuCy when the current through/voltage drop on that R gets too high. We would have to change the value of the R to make it open the FET (have enough V drop on it) when a certain current goes through it. But what about the losses then!? It would get mad hot, no? It did in this lesson! What's the problem and how do I do it "right"? Or will the higher voltage in reality (230Vac) on the high voltage side and therefore smaller current resolve the problem with the heat for me?
This is just a basic current controlled schematic, working, but, only for learning proposes, in real life no one it will use something like that, is 1000 time better in using a IC/Chip specialized for this. If you are replicating this, kudos to you, but the idea is only to understand how is working. Of course is getting hot, we didn't calculate the transformer, the pwm frequency and many other things, this is only for learning. Hopefully, after Lesson 40, we can run a live stream together and answer questions
I wish I had a teacher like you!
Thank you for making these videos, I found them very interesting and learnt a lot! Mulțumesc foarte mult!
Just finished the whole series up to last video. Love it. Can't wait for more. Awesome series Sorin. Thank you
Diana is learning quickly, more and more, I'm happy! thank you Sorin & Diana! 👋👋☺
Ce bine este explicat! Multumim si felicitari pentru material!
Really Enjoying this Series Hope You Guys Keep the Vids Coming and Hope Ya'll are Doing Great
This videos about smps are so useful. thank U👏🏻
Thank you.
Thank you very much. If I want more amps and the lamps were brighter, do I need a 3k ohm resistor?
Piękny układ na pająka 😊 Tak się w Polsce mówi. Na pająka 😅
Здравствуйте, хорошее видео)
FTJ-ul cu 10k si 3nF, are frecventa de trecere joasa, nu poate reactiona in limitele ciclurilor de comutare. Asa trebuie sa fie?
Ok the primary is controlling the current through the resistor 5homs, where is the feedback when u shorting the lumps?

Hi Thank you Can you make one or more videos how to find short in example in cuircute

f bine
Where is next video plzz upload video daily
why u are not uploading videos
why you stop uploading videos???
I suppose the channel is abandoned.
For some reason. Strange.
Next video
why no more videos
next videooooo???????????????/
I wish he spoke better English. His explanations are often somewhat confusing.
