- In this video we will explore the design and working of a closed-loop buck converter.
From its basic circuit to feedback driven circuit, we will explore it completely.
Correction: 6:05 - The duty cycle of PWM "increases".😅
Chapters:
00:00 - Introduction
00:17 - PWM
01:12 - Adding Inductor
02:30 - Frequency Increase
02:45 - Adding Capacitor
03:52 - Basic Buck Converter
04:13 - Closed Loop Buck Converter Circuit
04:20 - Operational Amplifier or Op-Amp
04:54 - Differential Op-Amp
05:30 - PWM Generator
06:08 - MOSFET
07:00 - Supply and Reference Voltages
07:25 - Normal Load (Output Voltage High)
07:37 - Double Load (Output Voltage High)
08:05 - Change Output Voltage
08:23 - Important Points
08:28 - 1) Voltage Divider
09:00 - 1.5) Load Change
09:21 - 2) PWM Generator (Reversed Comparator Inputs)
09:40 - Outro
The feedback does changes at 07:37 (Small change) but due to compression (Video + RUclips), The color doesn't change.😅

Good as this video is, it is yet another example of why it is important to have a human do the narration rather than a text-to-voice system. This video would likely have been better with a real voice.
Real facts there my man.
Good basic explanation.
An Analog voltage reduction uses resistance to drop the voltage,,which generates a lot of heat.
A Buck convertor storing the charge in magnetic Flux is far more efficient.
There is so much understandable information here that my brain can’t absorb it all in one view! Great explanation and video!! Must watch it multiple times.

Just replace the feedback circuit with Arduino,
i thought i'm the only one who keep repeating this.. but I agree this is great!!
Yo that's a solid ass video my man. Very very good. Step by step explanation. I never thought of inductors as becoming a battery due to their stored up energy in the magnetic field, and now that i think about it, it feels sooo obvious. Thank you very much
😮
This is the best channel on electronics for sure. So much detail and The explanation is perfect!
True bro!
Yep, I agree with you
Too bad it's a busted ass representation and explanation of what's going on.
Try "the engineering mindset channel " and then compare.
Triangle wave as a duty cycle template with the comparator is freaking genius.. never crossed my mind before.
Typically a sawtooth wave is used, but either way that's how it has been done for decades.
Linearity of the triangle or sawtooth is not critical since the feedback circuit cancels any effects of non-linearity. If you are making something like a signal generator then you do want very good linearity.
Excellent explanation and video, you explained things way better than my electronics engineering professors do, lol!
Unbelievably good video! Thanks for making it
seriously underrated video.
i will remember this video as one of the videos to watch learning electronics.
Explorer: is a best electronic channel ever as I found online till now. keep it up you are doing tremendous job.
Great Video with perfect Explanation and easy to catch the meaning
Nice to see that the circuit is properly grounded !! :)
By far the best explanation of Buck Converter!
ruclips.net/video/LiW5phNzwvc/видео.html 🙏👍👍
Amazing! Very instructive!
So much detailed video great explanation :)
Well explained. Excellent items also buck converters. Thanks for the great video. 👍👍
Wow just wow, no comparison of your video.
Great work man, just great.
Glad you enjoyed it!😄
@@ExplorerStuff could you please tell us which software do you use for making animation? if it's possible can you please make the tutorial on your animation?
beautiful, just a wonderful explanation!
Excellent explanation which I have never such explanation before
Thank you for this valuable information !
Great video ! With your permission, I have downloaded this beautiful video and I am looking forward to your next videos. Sincerely yours from Iran.
Dude you gotta come back, these videos are are the most amazing things i have ever seen
Just what I was looking for, and more! The animations really helped.
Very very good! Thanks a million 🤗
Love this channel keep going.
I wish I had this video in high school when I studied electronics
Which school teach this in high school 🤔🤔
@@omsingharjit in Skopje High School for electrotechnic and electronics Mihajlo Pupin
@@igorpetrusevski5399 nice education system
This stuff is not school level tech tbh, it is more like university level engineering;)
@@organicfarm5524 maybe in your country. In my country it's a high school material.
At university we learn to design the ICs
The explaination of Inductor and Capacitor in this video is sarcastically more understandable than those dedicated videos out there.
The videos help these concepts make a whole lot more sense
PWM is so useful in current regulation in everyday devices. Cheap, reliable components for speed control, etc are such a convenience
Wow, best explanation and video I have seen, very good.
Would you do one explaining a step up process ?
Thank you
Marvelous job!
It's a great knowledge
I'm also study electronics engineering and
This channel's video helpful
what stuff do you learn in electronic engineering?
i really do not think you study anything

Nice info, thanks for sharing :)
Bestest video on buck convert..thanku Sir
Excellent video 👍❤
Very very nice explanation👑with details👍
Wow that is amazing I will show it to my students. You could make a boost converter also, then an isolated topology would be nice :). Keep up the good work!
Thanks you so much. It would be an honor. 😃
Boost converter is next.
Isolated topology will be later, after inverter. 👍
@@ExplorerStuff Many thanks, I was looking for a buck converter and took advice from an Electrical Engineer that said he would never use a cheap converter because it can damage the much more expensive battery, BMS and load, but didn't explain why. So I went to Amazon and found lots of cheap $1 bucks that are tiny and one large for $20, I was confused by the large number of components on the more expensive one when compared to the cheap version as they both claim to do the same thing, now I understand why.
@@_John_P Glad it was helpful.😀
amazing tutorial, thanks.
thank you for you video,it's help me get the dc-dc convert point:the mosfet and the pwm.
Thanks for sharing this video Sir.
Amazing 👏🏾👏🏾👏🏾👏🏾
Thank you for making such a great video
Nice explanations ❤️wow!!
I am delighted with your video.
This quality of animation and simulation to ease the deep understanding could make your channel the best....ever ! :)
I am very...impressed !!! :)
The explanation is fantastic
Great explanation, I am glad I studied Mechanical engineering.

I am a mechanical engineer.. after watching this video, i understood life is difficult..
Very good👍
Thanks for your education
Very usefully and easy understand please more video
very useful science👍
Very nice Sir thanks 👍💐
Amazing..
I missed this. Thanks for everything.
Good work
Truly amazing!!
Wow nice video bro
very good
Because youtube is so awesome, they cannot show the dislike counter. For those wondering if this video is good information, this video is UNMATCHED. Everything in this video is true to an Engineering A+. The fact that PWM is discussed and how it is generated further shows a true engineer wrote this video. Excellent information. Thank you for your wisdom!
Superb
Good animation 👍
Great👍
Manh.. Really great content you provide 😍
Thank you so much 😀
@@ExplorerStuff most welcome sir.. Keep providing such amazing content.. Appreciate your hard work ❤️❤️🙏🙏
Very nice thank you
Very Easy Method For an explanation
Very very good
Brilliant
V nice 👍👍👍
So nice
Aku selalu belajar elektronik bersama teman ngamen... dan ini bagus...
Thanks dear brother
I recommend 0.75 x speed,
if you're using keyboard, click the video, hold shift and press < once
if you're using phone, press that three dots on the top right, and select playback speed, set to 0.75 x
I recommend 1.5x speed
