- 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 + TH-cam), 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
😮
Explorer: is a best electronic channel ever as I found online till now. keep it up you are doing tremendous job.
seriously underrated video.
i will remember this video as one of the videos to watch learning electronics.
Just what I was looking for, and more! The animations really helped.
Unbelievably good video! Thanks for making it
Excellent explanation and video, you explained things way better than my electronics engineering professors do, lol!
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.
Nice to see that the circuit is properly grounded !! :)
Great Video with perfect Explanation and easy to catch the meaning
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.
By far the best explanation of Buck Converter!
th-cam.com/video/LiW5phNzwvc/w-d-xo.html 🙏👍👍
Excellent explanation which I have never such explanation before
Thank you for this valuable information !
Well explained. Excellent items also buck converters. Thanks for the great video. 👍👍
Amazing! Very instructive!
beautiful, just a wonderful explanation!
The videos help these concepts make a whole lot more sense
Great video ! With your permission, I have downloaded this beautiful video and I am looking forward to your next videos. Sincerely yours from Iran.
This quality of animation and simulation to ease the deep understanding could make your channel the best....ever ! :)
I am very...impressed !!! :)
So much detailed video great explanation :)
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
Very very good! Thanks a million 🤗
Thank you for making such a great video
Marvelous job!
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?
Love this channel keep going.
Bestest video on buck convert..thanku Sir
Dude you gotta come back, these videos are are the most amazing things i have ever seen
I am delighted with your video.

thank you for you video,it's help me get the dc-dc convert point:the mosfet and the pwm.
The explaination of Inductor and Capacitor in this video is sarcastically more understandable than those dedicated videos out there.
amazing tutorial, thanks.
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.😀
Very very nice explanation👑with details👍
The explanation is fantastic
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
Nice info, thanks for sharing :)
Very nice explanation and fantastic animation
Really great videos. Thanks
Amazing 👏🏾👏🏾👏🏾👏🏾
Thanks for valuable explanation..
Thanks for sharing this video Sir.
COOL, electronics is always fun to learn
Thank you for video. 👍👍
Great explanation, I am glad I studied Mechanical engineering.
🤣🤣😂😂
Very, very good. Congratulations.
Excellent video 👍❤
Very deep understanding
That's amazing
Brazil, Great explanation.
Nice explanations ❤️wow!!
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
I missed this. Thanks for everything.
Fantastic 👍
Great job
Beautiful video..!!!
thanks for great work
Sir you are doing a great work please make more videos on electronic circuit designing
Truly amazing!!
good explanation .Thanks
nice Briefing. Very Good.
Wonderful.
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
Awesome video
Very nicely explained video
Thank you very much for your animation
Thank you very helpful
Thanks for your education
Great explanation. Please do one for hybrid solar inverter/charger
It's so amazing
Thanks for uploading nice video
Thank you this lesson
Very usefully and easy understand please more video
Amazing Animations.
th-cam.com/video/LiW5phNzwvc/w-d-xo.html 👍👍🙏🙏
Your work is excellent. Please go on!
Good effort. At 5:30, please note a Ramp is used as input to the PWM opAmp. Not a triangular wave.
Very nice Sir thanks 👍💐
Amazing..
Brilliant
Great👍
Aku selalu belajar elektronik bersama teman ngamen... dan ini bagus...
Great video!!! What tool did you used for animations?
Very good👍
Thank you.
Very Easy Method For an explanation
Very nice thank you
Superb
This is the video I was needing
ഭയങ്കര സംഭവം തന്നെ ഈ ഇലക്ട്രോണിക്സ്
very useful science👍
Thank you
Very very good
Good work
I am a mechanical engineer.. after watching this video, i understood life is difficult..
Thanks dear brother
very good
So nice
