Absolutely fantastic Teacher! Back in 1978, we were taught the simple formula that Frequency (F) = 1/t. I have not forgotten this. I am just an amateur that enjoys trying hard to fix broken electronics - whatever they may be. So glad that I stumbled upon your series of Tutorials. Greetings from Australia, and (if you are from Germany - Danke!
You're very descriptive and give a very good understanding on how this all works. You're helping me learn how these power supplies work and I look forward to more.
This video series is simply awesome, dont stop making them until you covered all and please...please if you can make them more regularly it will be really awesome
quite informative videos. there can not be a simpler way than this. i have never seen a tutorial like this. please keep it up so that we could get to know and understand the whole concept. we are waiting for ur next video.
Thanks for the encouragement! Now my health is a tad better, so I can sit down and make new videos. Btw, I hope that I am not your best teacher, because I consider my videos to have a really bad quality, so if others did even worse than my content, that is...
Thanks Peter, however I still have a lot to learn. When I listen to the videos I was uploading so far, I can barely stand them, they are like a drag. I think that I need to speed up the explanation a bit.
Thanks for the positive feedback. Some people do not like it that I try first to explain the basics of how SMPS actually work, otherwise there is no way someone would be able to repair them. Video 8 is now finally up. It took a while to produce, but hey, I am still around and kicking...
@@DonkeyLearningIT Yes, even to me it seems sometimes bit enlarged. On the otherside i am an absolut beginner and need to be more patient, get learning and finally go to practice exercises to get 'enlighted'. Would be even more fantastic if you could explain all this with practical use of measurement instruments and how to...(i.e. oszilloscopes, freq.counter..). Always a bit worry for cracking them up by wrong steps. However: Thanks a lot for your good, solid work. All the best for you, Donkey!
I appreciate your work put into this series. I subscribed to show you that I'm really looking forward to new videos. Thank you for sharing your knowledge in an area in which there is not a lot of good materials to learn from. Thank you!
Many thanks for the positive comment. Last two weeks I was moving to an other apartment so all my stuff was in storage and had no way to produce a video. However, starting the coming week there should be new videos coming up again. Also wish you all the best, when it comes to health all of us could use some better health and better luck!
@@DonkeyLearningIT that's good to know. I'm new to this still learning, if possible can you make a video ( if have sorry can't find it) on how an op am clearly works and I'm still confuse what an inductor do in a circuit, sorry slow learner here. Thanks again
@@edasplaces6451Regarding the OpAmp, there are several videos out there with hundreds of thousands of views, so I considered that the topic is well covered by people who have larger audiences than my channel. When it comes to the inductor, it will come back as a topic in video number 14 of the SMPS repair series, so do not worry, that will be explained again.
@@DonkeyLearningIT yeah you are right but believe it or not I have try searching someone who explain it like you do and I haven't found one yet, ill keep looking thank you
@@edasplaces6451Well, when I make the videos, I sit down for a couple minutes in order to try to come up with an oversimplified analogy in order to explain things. This might explain why you like the videos. Still, if you check the video on OpAmps from EEVblog, I think it should be still very informative. It has now well over 1Million views, so it has to be good.
Thanks for the comment! I promised to my subscribers that I will upload more frequently, and now I am having a bad cold one after an other. I hope that next week my voice will be at least good enough that one can understand what I am mumbling on top of the slides...
Thanks for the comment. Many people do not realize how much time it takes to produce even these amateur videos, so I cannot imagine what it takes to make good quality tutorials and also make them entertaining and education at the same time.
Thanks for watching the vids! Some people want to jump right into repair, but I think that would be the wrong way. There are plenty on "quick & dirty" repair videos out there for people who are impatient. Thus, I will try to make a systematic series of videos instead, where things are covered step-by-step.
Yeah! Exactly! That's what we are talking! If i want "tips" to fix them... i have an "entire" UA-cam set of videos... but i'm looking for your step-by-step learning process to be able, "in the end of the day", to understand how they work, and so, perhaps to fix them, too! Your job is "10", how we say over here! Congratulations!
Yes, money is almost always *that* thing what enhances our imagination. In my view also in high-schools young people should be though more about finances, because it would help them more than high level algebra.
At 01:57 Thank You! Thank You! Thank You! for not going over and over things that you have already explained in previous videos :) That way it is not tiresome to go thru your videos, but interesting new content :)
Yeah, I know. Some people like things to be repeated, otherwise they will say in the comment section that video was unclear. Other 50% of people complain, that I should not repeat things. I guess I will have to go with the no-repeat flow, otherwise the videos will be way too long...
@@DonkeyLearningIT - Yes, and by repeating things over of earlier videos will result in each video thereafter getting longer than each previous video :) You have numbered your videos, so it is easy to find the previous videos :)
@@TutterzoidIf each video would be longer than the previous, that would be indeed a problem in the long run. This is why in the newer vids I just mention that if people want to know what is it all about, first they might have to watch the previous video in the series. It is not nice, but it is definitely more practical, especially for those viewers who watch one video after an other.
Thanks in advance! I shall now enjoy this video! have looked forward for more of your next videos for quite a wile ;) I just recently stumbeld upon your BGA videos and really appreciated your thoughts and insight. Fantastic videos!
Yeah, most people do not have the patience to sit through those long videos for the BGA repair "guide". However, I wish that someone would have told me those informations before I put more than 1000Euros into an IR reworking station. Buying a handheld hot air unit is a lot better investment. Though, now with all those Bitcoin miners out there, the BGA repair might become trendy again.
Many thanks, I appreciate that the understanding is important to efficiently diagnosing, and as a bonus provides an insight into electronics which is more practical than theoretical.
I am glad that slowly the videos will come together. Sadly have some issues with my health, so had no time/mood to produce new once. Now I will start and make new videos, and pronounce "circuit" as it should be done, i.e. phonetically. Naah, just joking.
This is my continuation of last 6 tutorial 7 th is as usual an excellent presentation.really you are trying your best to explain given subject.thanks for video.
I have been trying to teach myself audio electronics repair for years, I have about a 50/50 success rate with repairs at the component level. I stumbled across your video in the middle of the night, as i was starting to go to sleep, as your video played my mind kept referencing all the times I ve read what you were teaching except now it all started to come together . not realizing I was wide awake I watched every video non stop. I want to say Thank you.I will figure out how to send a gratuity through you tube ...Thanks again.
Hopefully this time one will not have to wait 5 month for the next video ;) To my surprise, the number of views and subscribers/comments was growing in spite of not publishing new videos, so I said to myself that I cannot just disrespect people and not do my part of the deal...
There is no deal here, but you are an exceptional organized person, with fantastic teaching skills. I'm an electrical engineer myself, watching your videos for the pleasure of finding out how clear and simple looks your explanations for everybody, not necessary a specialist. I think it is an art to know how to select as few basics as necessary and slowly blend them in, towards the goal of completely understanding functionality of switch power source, no matter how dummy one might be. Congrats. If you could continue this series to the end, it would be a great service for a lot of people.
Thanks for the positive comment, really appreciate it. The idea of the series is *exactly* to explain these things to people who either did not have the time or the money to go and attend an engineering school. I honestly think that the current education system is broken. My small channel will not change that, but at least I might be able to help out a couple people.
@@DonkeyLearningIT iam glad that i watched your videos. they are full of knowledge cant wait for more vids on power supply switch mode or tv repairing in general. continue your good work.you are really helping many of us
Thanks for the comment. There are more videos in the series, so if you got the time, go through them. Also, in the next year I will upload more content.
Thanks for watching the video. I hoped I will soon upload new vids, but about three weeks ago I got a bad cold, and since I am just useless. Still coughing, and taking darn antibiotics...
I first came across switched mode power supply when attempting to fix halogen downlights in our apartment. Expecting to find a simple transformer with diode and capacitor, I found it hard to understand the strange circuit. There was scant information online, until I saw this series. Your lessons have been most beneficial. I now have several failed units that I would really like to fix. Looking forward to the next lesson.
Thanks for the encouragement people. Have some health issues, but I will be producing new videos soon out of respect, since people keep on subscribing to the channel in spite of me not publishing anything almost 10 months ago by now.
What a pleasant voice. Yes you are pronouncing "Circuit" better, but I liked the way you did pronounce it - lol. A lot, lot of detail dude. We still haven't gotten to the repairs yet, but it is important to understand the theory for the youngsters.
Yeah, I was having issues with my health (I hate winter...) and being busy with my job as usual. Still, in the future I should take this channel seriously. If I would have put in a bit more effort, there would be a lot more contents uploaded.
I love the video but I simply cannot understand how a transistor can act as a resistor, especially since the resistance between the collector and emitter is very small whenever the transistor is on. Can you please explain this, Thank you.
Hello. I need your help. cisco me3800х does not see the console, does not load. Hot elements on the board are detected. (q27, q48 (7860 saf)) on the line 1.0 v) Help in troubleshooting. If possible. Thank you.
I need to finish those videos first. My video creation toolchain is very inefficient, so it takes me hours to produce a half-decent 20 minute video. I hope that this will improve when I publish vids more often.
Thanks for expressing your willingness of supporting the content financially. I really appreciate it! Never wanted to make money from the content, but so many people have asked me about this, that most likely next week I will put up a PayPal button for people who got money to spare. With a bit of money invested I could buy better equipment for the channel, or even teardown/repair items. For example, the camera I am using is an 8 year old Canon.
I also started watching your series because I wanted to repair my ATX 750W power supply. It was running fine then my computer just shut down and then would not turn on except the fans rotate just for a second and the lights blink when I press the power button. This will not happen again if I press a second time unless i switch off the main power and then replug again and try. Can you please help what could be possibly wrong with my Power Supply and how can I repair it. Thanks.
Thanks for watching! It took almost five months for publishing an other video, and that *is a shame* on me. In this year I will publish stuff more often, since people are actually watching the videos, which surprises me.
I was just wondering about you the other day. Wondering if you had given up on this, a danger I had mentioned to you. Thanks for continuing. Waiting to hear about Shottkey diodes and MOSFETS. Probably next year 😉
I do not give up easily. Got the patience of a donkey ;) That is why I got that as my username. Though, the pace got really-really slow, so now I need to shift gear and pick it up. As for Shottkeys and MOSFETs, we might do it this year if all goes "horribly right". Just joking, it should not take that long.
Teacher, in the datasheet of a led, there is duty cicle "x", is this PWM critical for the operation of the led (component)? Need to create his circuit, with the specific pwm, correct? Thank you.
Yes, the duty cycle is exactly in the upcoming video, which I will hopefully will be able to finish and upload. The idea behind using PWM for an LED is, that for a short period of time one can feed the LED higher current than if one would feed it with a constant current. However, this time period must be smaller than the duty cycle defined in the datasheet, otherwise the LED will burn out.
Well, I had/have some issues, so producing new content was on the backburner. Still, now I will produce new videos. If you check back to the channel, now video 8 is uploaded.
Donkey Learning IT great news , i really enjoy and more importantly understand the way you explain things , wish i had a teacher like you when i was in collage , i cant wait for your next videos , keep up the good work ...
Nah, I live on a different planet which has different number of days in a year. Just joking of course. In the heat of the explanation I made a dumb mistake and forgot to edit it out.
where is the 8th ? you are very good at explaining and teaching, without to mention your great spoken english. let me know, please, when you will launch the 8th video. i'm looking forward to it.
Absolutely fantastic Teacher! Back in 1978, we were taught the simple formula that Frequency (F) = 1/t. I have not forgotten this.

REPETITION is a very good way of learning/teaching! no one should tell you how to approach the Subject you are doing an excellent Job
Up to now, you're the best teacher I ever encountered. Keep up the goooood work. Thanks a lot.
This smps series has been awesome. I love it thank you
the SMPS series is very useful for me and you explain very clearly thanks for your effort i love it ;)
Very good video explaining the fundamentals of Pulse Width Modulation.
You're very descriptive and give a very good understanding on how this all works. You're helping me learn how these power supplies work and I look forward to more.
Nice explained. Thanks.

What we have, at the end of the day, you're a great teacher Donkey, I can tell you! Thanks!
Thanks Peter, however I still have a lot to learn. When I listen to the videos I was uploading so far, I can barely stand them, they are like a drag. I think that I need to speed up the explanation a bit.
Thanks to you again after two years , now it 2020 , didn't watch your videos until now ( because of life situation here ) . Keep it up bro
Unbelievable, taken me in new directions.... Great series, please keep going, can't wait for 8 and beyond!
Thanks for the positive feedback. Some people do not like it that I try first to explain the basics of how SMPS actually work, otherwise there is no way someone would be able to repair them.

Over 3 years later and this video was just found. Excellent! Thank you! I was shocked to hear you say "sir-kit" :-) "Sir-quit" was ok by me too.
This is the best series about SMPS on youtube, keep on the good work.
Thanks for the feedback. I will try to upload a new video every week, so hopefully there will be the follow-up coming this week.

Yes, money is almost always *that* thing what enhances our imagination. In my view also in high-schools young people should be though more about finances, because it would help them more than high level algebra.
These are good videos i pretty much knew most the important parts and I was looking for a shorter video just to see but here i am

You are a blessing. God bless you for giving help to us.
Many thanks for you positive vibe.
I could definitely use some good blessing, as most of us everyday people.
Wish you all the best as well!

When you will make video on power factor correction (PFC) .
I have already watched most of video .
Finally...part 7 arrived.
Yeah, I was having issues with my health (I hate winter...) and being busy with my job as usual. Still, in the future I should take this channel seriously.
If I would have put in a bit more effort, there would be a lot more contents uploaded.
Take your time. But please complete this series. This is the best series on SMPS on youtube.
u are so great sir.thanks for sharing.keep it up.
The contents could be better (especially the audio is clicking because of the cheap microphone I am using) but hopefully it is still good enough.

I do not give up easily. Got the patience of a donkey ;) That is why I got that as my username. Though, the pace got really-really slow, so now I need to shift gear and pick it up. As for Shottkeys and MOSFETs, we might do it this year if all goes "horribly right". Just joking, it should not take that long.
Whatever you do it is appreciated. Don't knock yourself out.
Teacher, in the datasheet of a led, there is duty cicle "x", is this PWM critical for the operation of the led (component)? Need to create his circuit, with the specific pwm, correct? Thank you.
Yes, the duty cycle is exactly in the upcoming video, which I will hopefully will be able to finish and upload. The idea behind using PWM for an LED is, that for a short period of time one can feed the LED higher current than if one would feed it with a constant current. However, this time period must be smaller than the duty cycle defined in the datasheet, otherwise the LED will burn out.
How is the health? Are you going to be able to finish the series?
Many thanks.. so when is the part 8?... cant wait...
Danke Danke Danke. Enfach toll !
Sehr gerne!
Good one. i have viewed all the 7 videos, but where is the continuation?
This course is excelent. I'm waiting for the Switch mode power supply repair #8.
Thank you very much sir, I'm wait for next tutorial video
Is there going to be a part 8?
Yep, there will be. I am not a young guy no more, so have to take care firs of getting back a bit into better health.
Where is the rest of the smps series ? Great videos very informative 👍🏻
Well, I had/have some issues, so producing new content was on the backburner.
Still, now I will produce new videos. If you check back to the channel, now video 8 is uploaded.
Donkey Learning IT great news , i really enjoy and more importantly understand the way you explain things , wish i had a teacher like you when i was in collage , i cant wait for your next videos , keep up the good work ...
Woohoo your back!!!!!!!!!
I am saying the same like Bender on the first episode of the last season of Futurama: Yeah, we are back!
When is part 8 going to be released
nooooo, I loved the way you pronounce circuit
Where is the part 8..?
11:18 I think you mean 365, or am I wrong?
Nah, I live on a different planet which has different number of days in a year. Just joking of course. In the heat of the explanation I made a dumb mistake and forgot to edit it out.
@@DonkeyLearningIT no worries man, the videos was so very "edu-taining" I'm sure very few people noticed.
where is the 8th ? you are very good at explaining and teaching, without to mention your great spoken english. let me know, please, when you will launch the 8th video. i'm looking forward to it.
