I spent hours trying to get my head around buck converters the other night and now you've explained it completely in five and a half minutes. Great job, thanks!

@greatscottlab 8 лет назад

+Carl Alm Thanks for the compliment ;-)

@miguelfierrospena6758 8 лет назад

+GreatScott! can you make a tutorial for DIY FLYBACK control by PWM? please

@virenlakum 8 лет назад

+Carl Alm Yeah same happened with me. I had my project ready but i accidently used adjustable version with no feedback so jumped back to 7805. Now i understood my mistake. Great work +GreatScott!

@kenmore01 3 года назад

@@miguelfierrospena6758 It's basically the same, but they are current controlled. That's good because they do limit current well.

@sheeplord4976 Год назад

the simple way to think about it is that, at high frequencies, the average voltage on one side of an inductor will equal the steady voltage on the other side.

@markjones3121 4 года назад

Fast, efficient commentary, nice use of oscilloscope to demonstrate effect of each component and components used named and specified. Beautifully done! Couldn't be better.

@rahulrbharadwaj123 8 лет назад

I got interested in electronics due to your videos!! Thank you so much! I'm now building an automated robotic arm! :)

@SimonStuff2000 3 года назад

You should build a electric car! :D

@AkhilRane15dec 5 лет назад

I love your ways and methods of teaching. Wish I had a professor like you during my Electronic Engineering days. Short Crisp and well edited videos. Full of information and practical know how... Thank for sharing your knowledge...

@abegafouda9136 3 года назад

Merci. Now you're even GreaterScott because of the French subtitles... Thanks to you and to whoever devoted to do it. It's just perfect.

@jakub6094 8 лет назад

I didn't know much about electronic, but now I have watch your videos in about 5 months and I learned something. Thank you Scott for making RU-vid a better place (:

@FronbondiSkegs 3 года назад

Definitely the best explanation of how the various parts contribute to the buck converter, that I've ever heard.

@HeiwaAsobi 8 лет назад

I love these theory videos that explain a concept. You're incredibly good at it. You're like the hobbyist version of the "The Great Explainer" Richard Feynman.

@chocoolatey 7 лет назад

I saw this video a couple weeks ago while learning more about electronics while knowing Basics. I understood parts of the video but a lot I didn't. After going through many more of your videos and other peoples videos I came back to this and understood it perfectly. So if you were like me and did not understand everything from this one video, don't worry and just go look through more of his videos and other video that explain other electronic component uses and some theory and come back after a while and you will understand a lot better. So thanks for the education GreatScott!

@rpgquestboard 8 лет назад

Great video! One of your best yet. haven't found many short and to-the-point DIY buck converter videos on RU-vid. They're usually split into 5 parts and never get around to building the circuit.

@bazrazin1 8 лет назад

didn't understand inductors fully in my education, but with the scope waveforms everything is crystal clear, now kinda like inductors amazing component, best explained ever.

@donaldfilbert4832 8 лет назад

Fantastic video - thanks a ton !! Love your quick paced; well thought-out content approach; and perfectly edited style !!

@MichelPASTOR 8 лет назад

Very nice buck SMPS tutorial. Short and clear. Right on point.

@dheujsnrhfydhehehshshhdggsd 8 лет назад

thanks for the oscilloscope portion , it was helpful to see why we need better regulation for sensitive projects

@vgamesx1 8 лет назад

Great explanation, I really like how you added one component at a time then explained why you added it and what it does to the circuit, most tutorials I've found don't really go into detail on why you need an inductor or a high switching frequency as an example, Thanks.

@Ragingwasabi9000 8 лет назад

+vgamesx1 yea defintiely very well structured videos!

@hurtadoa1 8 лет назад

I see you doing these things and it sparks my interest in studying this field. It seems to be great and fun to Learn how electricity works

@fidelgomez1842 4 года назад

May I say thank you for your wonderful video. I don't know much about oscilloscopes but may God keep giving you the tools you need to be able to teach us. Thank you very much

@tobimai4843 8 лет назад

Cool, this is the first time I really understood how switch mode PSUs work. Keep up the Great Work :)

@zerodegrekelvin2 5 лет назад

GS..I used to know IC chip names by Heart and By the Family...watching your channel has brought back the inner geek in me.

@rberg79 2 года назад

amazing and beyond my comprehension at around 4:25. Awesome video. I am just a beginner so it is good that I stayed with it for that long.

@Exo5432 Год назад

Ofcourse I go searching for a good video to diy and it's a great scott video as usual. Keep up the good work and helping the world with knowledge

@acestudioscouk-Ace-G0ACE 2 года назад

This was the tutorial I needed, thank-you!

@rajgupta9992 4 года назад

Beautifully explained.

@matgggg55 4 года назад

I have legit learned soo much from watching your videos over the years , I had no idea I was learning as much as I was , until I found my self predicting the next components you where gonna use ... I have no formal education on electronics , just RU-vid and tinkering my self

@tehgringe 4 года назад

Perfect. Exactly what I was after. I'm currently building my own LED strip light driver and controller. Got an esp32 for wifi and lots of pwm. Using some logic level mosfets in there for switching the 12v but I want to power the entire board from a single 12v DC jack. Need to add a buck converter onto the board.

@verargertesspielen4629 8 лет назад

@uberawlaa1056 8 лет назад

you are just awesome man! just perfect. I am a student of electrical engineering in Pakistan (Asia). But unfortunately, we aren't being taught these things here. Just bookish crap. I wish I could work with you. I make small projects in my house. I love it. but I will die to learn all the knowledge you have got.....! love you sir!

@richardsandwell2285 4 года назад

To novices who are scared of Switched-mode your explanation made things really clear and easy to understand.

@llewellynpatrick160 4 года назад

I really enjoyed the way you stepped us through the development of the circuit - very well done. Having checked out your other posts I can see I'll learn a lot here. Subs +1.

Just what I needed it! thanks a lot!

@xAbdulRhmanX 8 лет назад

Thank you very much just what I needed :) I used an arduino to open/close my car using my phone (new project in your channel??) but my problem was the power I did not want to use linear voltage regulator so I looked into the buck converter and they are awesome !! thank you for your video it makes my sunday better. I am AbdulRhman and I am from Saudi Arabia :)

@EngineeringNibbles 8 лет назад

Eddy Fuchs HE DID ? WHERE ARE THESE MAGICAL PLACES WHERE YOU GET FREE 5000€ SCOPES ??? I don't even own a fucking working dishwasher and i'm busy drooling over these expensive things :o

@eddyfuchs1 8 лет назад

BillTheBox Yep, Keysight got a generous giveaway month recently, one scope every day, one super scope every week and one super scope for many youtubers

@EngineeringNibbles 8 лет назад

Eddy Fuchs when and where did this happen ?

@eddyfuchs1 8 лет назад

BillTheBox In our known Universe in the Milkyway in our known sunsystem on earth (you're not dreaming) and I think it was this March
