Really nice series... I was learning elerctronics at high school but i have no clue how to repair a power supply. These videos helps a lot, cause they dont start at the nonsense p-n transition. Keep up the good work.
I wanted to keep the content as simple as possible. At some time I will have to talk about semiconductors, but I definitely will not cover solid state physics and such. Main thing is what a transistor or a diode does. How it does it is not so important as long as one is not trying to design new stuff.
Thanks for the positive feedback. Actually RUclips is thinking the same, since it has put DiodeGoneWild into related channels if you check my page. Thus, in some sense the algorithm is pretty darn smart.
Thanks for the comment. I am a bit tight on time since I need to pack up my stuff before I move next week, so lets hope that I will manage to finish the video.
Can you please share your component values so we can replicate the results and, therefore, learn hands-on? That would be very helpful. Great video, thank you.
Thanks for the positive comment. I hope you are "hooked" in the right way ;) Sadly I am so swamped by my job nowadays, that I rarely got time to sit down and produce new videos.
I hope that I will be able to keep up making decent educational content as long as my health/time allows. Although the channel views are growing slow, I still prefer this way. People who want to learn will watch my videos in spite that there is no techno music in the background and fancy editing effects.
Nice, clear explanation. One need to pay attention to the degree of compensation you get with one diode at the voltage of interest. If needed you might add a second compensation diode in order to improve the zener's tempco. Of course you will add twice the amount of regular diode voltage.
Ahmed Ali Hi, If you watch a video for only a few seconds, RUclips interprets the video as potential clickbait. I don’t know how that would work out in combination with a like. I just wanted to let you know this as you clearly want to support the Dr. (and so do I;).
Thanks for watching the videos. Last two weeks I was moving to a new apartment, so all my stuff and editing computer was in storage. Had no internet either. This Sunday there should be a new video finally out again!
I am not sure I will ever do actual design videos, since those are really heavy on math and control theory. However, I want to cover the basics of how SMPS (and first linear PSUs) work before we can go into advanced repair.
i have been following your videos sir. am always waiting for your new videos especially the smps series though am new in electronics. its not easy just hoping that one day i become somebody in electronics. thanks once small thank you, you are really doing a great job
@@patrickblessedtembo3664As a real life advice what I can give people who want to get into electronics is: Just do it! Of course, at the beginning start out with small low voltage low power projects, and your knowledge will rapidly grow, trust me!
Another great video, Mr. Donkey. I hope you will manage to keep this way in the next episodes, highly biased toward the practical aspects of the circuits (such as in this case the role of silicon diode in temperature compensation). Too many times I saw on youtube channels starting promissing and then somehow getting far too basic and explaining fundamentals and what a capacitor does as if there are not already thousands sources where you can find out what a capacitor is. Please rezist the urge to become too basic, newbies are already well served by thousands other channels.
Thanks for the comment. Regarding the issue of channels going far too basic the problem is, that many people are not patient enough to learn first the basics, and they ask super basic questions. Also, if one would like to grow a channel fast, the right way to go is to explain very basic stuff over and over again. I try to keep the channel going practical aspects and minimal theory what is really necessary to understand roughly how things work.
LOL, I was doing some research to operate a relay and keep finding silicon diode with zener diode in schematics. I also had no idea and there were no explanations!
For a relay it might be a bit overkill to use thermally compensated Zener, so I am also wondering why would they design a board like that. Anyway, when I was young I had no idea why there was a diode in series with a Zener either.
YouGenom In DC you put the silicon diode across the coil for a snubber, you can do the same thing taking a zener from the bottom of the coil to ground. You are snubbing the excess voltage caused by the magnetic field of the relay coil collapsing. A relay coil, like an inductor does not like to see a change in direction of the current flow. Without the snubber, you will usually destroy your switching device i.e. Transistor.
Hi Dr., Tx again for another dosis of SMPS medicine. It seems to work quit well! Do you have any idea how many dosis are yet needed before we all are completely cured of SMPS-obliviousitus? Tx again from your loyal patient.
I am afraid that it will be a long treatment. There are several topics where we have not even scratched the surface yet. After the error amplifier I have to start discussing transformers as coupled inductors in SMPS.
Yes, sometimes diodes are willing to tell you *the truth* only after you torture them for hours. No diode was harmed during the making of the video though...
What you are saying is very, very, VERY clear. I really enjoy your videos, keep it up and thank you for the content!
Thanks for the positive feedback! I am glad that the content is being educational.
Yes my brother,he says by heart.....you can never see ,what is not here in any ref book across the planet....
Thanks for coming back to finish smps videos.
In the last months I had issues in the family, so I simply had no will to sit down and put together content what is halfway good. Sorry for this...

Great educational channel. Reminds me of the DiodeGoneWild youtube channel. Keep up the good work. Thank you.

Thank you for yet another excellent video!
I am glad that you like the content!
Second
Thanks for the next video in your series. Looking forward to the next installment.
Thanks for the comment. I am a bit tight on time since I need to pack up my stuff before I move next week, so lets hope that I will manage to finish the video.
Thanks for your wonderful presentation.
Thank you for taking the time to create this video !
You are welcome. Also thank for your time for watching and commenting.
Great video, with a good explanation. Many thanks! Keep'em coming. Cheers
Thanks. Hopefully next week I can upload an other video.
Can you please share your component values so we can replicate the results and, therefore, learn hands-on? That would be very helpful. Great video, thank you.
Thank you for your time and efforts. You're a good teacher !
your videos are like GOT tv series ..i am hooked
Thanks for the positive comment. I hope you are "hooked" in the right way ;)
Sadly I am so swamped by my job nowadays, that I rarely got time to sit down and produce new videos.
Really glad your producing videos again. Well Done.
I hope that I will be able to keep up making decent educational content as long as my health/time allows. Although the channel views are growing slow, I still prefer this way. People who want to learn will watch my videos in spite that there is no techno music in the background and fancy editing effects.
Fantastic video series, one of the best on the subject on the Tube, thanks a lot for sharing your knowledge. :-)
Beautifully explained. Keep it up and thanks a lot for this series on SMPS.
Thanks for the comment. I will try to produce a video every week.
Nice, clear explanation.
One need to pay attention to the degree of compensation you get with one diode at the voltage of interest.
If needed you might add a second compensation diode in order to improve the zener's tempco. Of course you will add twice the amount of regular diode voltage.
Looking forward to the next discussion.
I will have to pack my stuff since I am moving to a new apartment next week, but lets hope that I will have time putting together a video before.
Very good explanation. Looking forward to the next episode. Great Job. Manx thx.
I am happy that you liked the video! If all goes terribly right, this Saturday there should be a new video up as usual.
Thanks. So Im waiting for next video.
I will try to make an other video next week. I will be moving to an other apartment in a couple days, so I should pack up my stuff.
i dont have enough time to watch it right away but i keep liking to convince you to make such good content in near future.
@@AhmedAli-sn3tyThanks for the like! When you got time, just watch the video, it should be educational.

Super teaching ....
Best series I found
at 8:37 isn't the zener facing the wrong way in the schematic? shouldn't they both be facing the same way for current flow?
hello, at 9:50 why is it not Vout = Vz - 0,75V? i do not get how the series silicon diode raises the voltage.
Ten videos up to now....looking forward for more.
Thanks for watching the videos. Last two weeks I was moving to a new apartment, so all my stuff and editing computer was in storage. Had no internet either. This Sunday there should be a new video finally out again!
good video...we will be experts by the time we reach the smps design. :))
I am not sure I will ever do actual design videos, since those are really heavy on math and control theory. However, I want to cover the basics of how SMPS (and first linear PSUs) work before we can go into advanced repair.
Different diodes are also used on some integrated circuits for biasing and switching levels.
Thanks for the latest episode. :)
You are welcome! Hopefully in the next week I will be able to upload the error amp and feedback loop.
the best teacher ever
Thanks for the positive comment. If you got time and like the content, go through the other videos in this series.

Anlamadım ama yine de sağol.
Tried to translate via Google. If I got it right, the video was not clear. Sorry for that.
Sehr gut
In power grid.
we have seen 3 phases.
How do 3 phases create Ground?

Donkey Learning IT
Ah, complications. I was -afraid of- looking forward to that. 😉
@@Conservator.Haha, that is actually funny!
2 batteries in sery .the meeting spot between +and - also create Ground.
Why?
Ground is just a point, and you measure voltage compared to that as a reference point. It is like sea level compared to which we measure altitude.
good good good
thanks thanks thanks ;)
Weee :D :D
Another episode :)
The saga continues ;)
Best ever and hopefully up to the end.
U da man :D
Dr Donkey is torturing a poor zener diode 😂
Yes, sometimes diodes are willing to tell you *the truth* only after you torture them for hours. No diode was harmed during the making of the video though...
