How to Design Buck, Boost & Buck-Boost DC-DC Converters

[@dystopian-me]

This channel breaks down boring power supply circuits taught in class using a hardware puzzle approach. Power electronics might feel dull in class, but this is a fresh, exciting way to learn!

[@electrarc240]

Exactly! It was mostly taught in a very boring/confusing way at uni and I couldn’t understand why they were teaching it that way, cause it’s really cool stuff!

[@JarheadCrayonEater]

This is beyond outstanding. I've been a programmer, Metrologist, Control System Engineer, and Turbofan Test Engineer working on troubleshooting, repairing, designing, and building circuits, but have never seen something this detailed and educational in all of my 46 years. There really needs to be an award for this kind of effort and educational information!

[@Conservator.]

I couldn’t agree more. 👌

[@solidiv]

I totally agree, fantastic video :)

[@electrarc240]

Wow thank you so much, I'm glad the effort shows as this one took a lot of time!

[@JarheadCrayonEater]

@@electrarc240 I'm sure it did! I couldn't imagine the effort required to make this video. Like I explained in my original comment, I've had a lifetime of exceptional experience, but you somehow brought all of it together and exposed it in a way that's just perfect! @Conservator and @solidiv also agree. You deserve some kind of award for having such an outstanding presentation! Tell your wife and kids that you are the man, because you are!

[@Tatersalad812]

Im not sure where to start, How ABSOLUTELY amazing everything is done! Graphing, Explanation's, and best of all you are using what most people have for a scope so we can follow along at home. I feel bad now asking when this would drop. Doing this on top of a full time job and LIFE is crazy! Thank you for all your hard work and let us know where to donate to your bad habits because after this you need some rest lol

[@electrarc240]

Life? What's that? Haha thank you very much for the kind words though and no worries for asking when it would be ready, I was hoping to have this out two weeks earlier but I massively underestimated the work this one would take. You can donate on PayPal if you really feel inclined, but honestly I'd rather you put the money towards a project! I will probably make a Patreon once I'm back at uni in about 6 months if you'd rather wait for that. As for the scope I'm glad you appreciate that because I have been offered better scopes but I am trying to keep everything I show as accessible as possible, same with the JLC sponsorship I've used them for years and am happy to recommend them, whereas I'd feel uncomfortable if I were sponsored by a company that offer products out of reach of the average viewer.

[@Tatersalad812]

@@electrarc240 Sounds good to me, If I saved my money for a project id just end up with yet another project. I wear many many hats, none fit all that great but its a hat! Im recovering from 2 back surgeries back to back no pun intended. I now have Titanium and rubber in my low back and my steps per day are very limited even 1.5 years later, also still not back to work (industrial maintenance) probably never will in that field of work again. So now im 34 and trying to find a new career that keeps my brain busy and my butt planted and its very hard. I downloaded kicad and started watching your videos on design. Im doing lots of diy smart home stuff and making my own breakout boards for esp32 is on my list of things to try. I wish I had half your brain when it comes to this stuff. Ill wait on the patreon since ive never gone that route before, and it give me time to save up a little. So much detail and explanation deserves something time isnt free!

[@stephengfazio]

I just finished a course in power electronics at Georgia Tech and it was purely theoretical and lecture based. Watching through your videos helped fill in some of the hand on lab experience. Thank you for sharing and keep up the great work 👍

[@wirelessnet2747]

What class code?

[@stephengfazio]

@ ECE 4330. I loved the class, like it put together so many fundamental principles directly applicable to my work. We didn’t build anything, but did have a project with sourcing components and simulation Videos like these bridge that gap into application. I bet Electrarc was a TA at some point the way he explains things by systematically breaking down and simplifying them

[@electrarc240]

@@stephengfazioah I wish! Haven’t even graduated yet, but going to try to be a teacher as soon as I can

[@stellamcwick8455]

ElektroBoom is entertaining, this channel is educational.

[@BillDemos]

Like all your content. Like the extent you went into to couple the math with intuition. So high quality content, a rare gem for youtube.

[@fares3651]

Bro keep cooking

[@dystopian-me]

In today's era of ready-to-use modules, studying circuits component by component has become a rare practice for most people.

[@justanormal16yearoldkid51]

Which channel is so underrated, this man can explain anything in terms of simple language love your video sir ❤

[@BogdanSerban]

That's probably the most interactive course on how all of this works.

[@CppExpedition]

Not missing a single video of yours🎉

[@MarcIzq2]

Amazing video! The explanations were clear, and I love that you showed voltage and current waveforms for each part of the circuit, as it makes it very clear what's going on and makes the whole explanation very intuitive. Love your content, keep it up!! I hope some day you make a similar video on flyback DC-DC converters, I've been trying to design an adjustable 0-24V @ 1A flyback transformer as a pre-regulator for a linear power supply and never figured out how to properly design them to work on a wide range of voltages (as opposed to a fixed output voltage)

[@electrarc240]

Thanks! I will certainly try to cover flyback converter's at some point, though there are a few pre-requisites I want to make videos on first

[@samgbtembo]

This right here is pure Gold.

[@Rafael-p5s4s]

a gem of a channel, please keep this going, really learning a lot from you

[@lad4694]

Yay. Tis the season to be jolly

[@electrarc240]

Ho ho ho

[@HerbaMachina]

Bro is really out here producing the best and most comprehensive, yet engaging and well thought out electrical engineering videos on KZbin. We all thank you for your service good sir 🙏🙏🙏

[@siener]

Here's a video idea for you: Go through the process of designing a power supply for DIY Eurorack modular synth projects. The standard calls for -12V/0V/+12V outputs, so it's one of the few places where you want the negative voltage that a buck-boost converter can give you.

[@bennetting1609]

Just in time for Christmas 🎁. Thanks for another brilliant video!

[@darkshadowsx5949]

i need to watch this when im not tired. brains not co-operating.

[@lad4694]

That output voltage "hump" between 0.2 - 0.8 duty cycle at low load blew my mind... I'll try simulating in LtSpice to see if i can gain more insight before i start pestering the internet with questions 😂😂

[@electrarc240]

Yeah I'm so glad it came out so nicely in the graph! Feel free to pop any questions here or on my discord server btw

[@rydjaradat]

OK very nicely explained, here is a challenge add a microcontroller to control both Vout and current limit (I load), I trust you can do it (dont drive the mosfets from MCU, but from a didicated switching IC).

[@electrarc240]

It already runs from a microcontroller, the same one that communicates with the power monitors and the PC. So adding closed loop shouldn’t be too difficult. I’ll definitely do a video on control one day!

[@SnakebitSTI]

43:26 This video has been very helpful! I'll stick with linear regulators! Mostly because I tend to mess with very low power circuits.

[@electrarc240]

Yeah they’re definitely better unless you need significant power

[@phonix6494]

Very nice video thank you for sharing

[@_FJB_]

Love these! Very informative.

[@MyProjectBoxChannel]

Grate content😉👍 It's refreshing to see a youtube video 44min long, and that you are not tempted to squeeze it down, by skipping over things. I suspect most people will watch all of it. Maybe I might consider not manically trying to edit 3 hours of video down to 15min. I always felt I'm leaving important stuff out😢. I hope you will carry on the good work. Thank you for all your hard work. How do you find the spare time for such ambitious projects 🤔?

[@electrarc240]

Thank you! I agree I never see much advantage to skipping important things just to shrink a video down for more clicks, I'd much rather make a single conclusive video on a topic and people are free to skip parts if they want. I think in terms of finding time to make the projects it's a combination of doing very little else in my free time like socialising or sleeping, and also I think I've become quite quick at designing boards and circuits for these demonstrations. Probably helps that I spend more time than I should thinking about videos at work too haha.

[@shravanbg4270]

Keep going Bro 💪

[@jameshancock]

Love your videos. Would love to see how to build and fire out a bidirectional half bridge. This videos finally showed me how it might work but I’m still struggling understanding the bidirectional flow and how you’d manage it so that the flow goes where you want. (Ie 40v to 4v and visa versa for battery charging and discharging with say a solar panel and a load on the 40v side.

[@electrarc240]

Yeah that is confusing to wrap your head around. I guess if you had ideal 4 and 40V sources and an ideal converter then 10% duty would get no current flow and you’d make it flow either way by slightly reducing or increasing it. Of course nothings ideal so we’d have to sense the current and vary the duty cycle based on that. I’ll try and cover it at some point

[@blays.7178]

Thank you for this.

Good stuff. But I couldn't keep up lol.

[@electrarc240]

Ah sorry I’ve heard that a few times recently, I’ll try and pace things a bit better in the next videos. This was a lot to fit into one

[@Friendroid]

@@electrarc240 it's fine, we can pause and rewind, the content is great!

[@SnakebitSTI]

With some of this stuff, I think it helps to fiddle with a breadboard, let the magic smoke out of some parts, then go back to review what you misunderstood.

[@JKTCGMV13]

hell yeah

[@fluteplayerify]

Which thermal camera did you get? It looks like it has a good frame rate.

[@electrarc240]

It’s a FLIR One Pro, mostly got it for the high resolution and accuracy. It’s a little over 8FPS but probably looks better here cause it’s mostly sped up footage. Still just about fast enough for non-engineering activities if one were so inclined.

[@raulopatriot9034]

Hey, where can I buy those boards you use in your videos?

[@electrarc240]

I’m afraid they’re not available, but you can design them yourself! Only took me a day or two to do them all

[@raulopatriot9034]

Ok thank you

Bro, if you want me to show your vids, stop using auto synch and translate

[@electrarc240]

Not sure what you mean?

[@viktorkunz189]

@electrarc240 Thanks for responding! In the settings of the YT Studio there's a setting for to auto synchronization of supported languages activated. So the vid is showing titles and speaking in german, which is my native language. Pls deactivate it, so the information doesn't loose its sense. Thank you!
