it's amazing how coordinated you Phil are with what I do LOL. The day I got my hands on the Zynq7000, a few hours later you uploaded your first video to it. Today I took the first measurements on my 3kW boost converter and there you are. Ah yes, the boost works but the inductor has 200W of core losses :P choose the ferrite well lads...
As always, an excellent presentation. Would love to see a vid on flyback converters. I made a flyback with UC3843 12v to 300v to run a DC capacitive discharge ignition system that I designed. It works OK but I'm not an expert by a long way and I'm sure that I'm missing something important. Particularly the snubbers are a little tricky for me. But anyway, keep up the great work. Most of your vids are way above my pay grade but super interesting none the less. Cheers Matt
This was well done, short and dense. I'm off to watch #106, got a couple questions. What's your experience matching simulation results (assuming the models are ok) to circuit measurements for boost converters? Also, say the boost converter doesn't quite work, how would you go about finding the error in component selection? Maybe these are topics for future videos. Personally, I'd like a boost converter from 18V to 400V@100mA for some vacuum tube guitar amplifier designs. These requirements are far outside all the common tools available like the Mouser/DK/TI search engines. Thanks for the video, it was exceptional.
Thank you very much, Craig! Those are great questions and definitely worthy of some videos. In particular for simulation, that's a great idea - I wanted to make some more on SPICE sims in any case. For boosting to a high voltage, if you can bring the current requirements down (e.g. for a guitar valve pre-amp), then I'd suggest a Dickson charge pump for simplicity. For a power amp with valves, I would go the AC, transformer, rectifier route.
Thank you for this video. I learned alot with this videos to design my own pcb with buck or boostconverters. But i got a question. Seems like the inductance is very related to the output voltage so how do i do it when im having an adjustable outvoltage?
Would be interested in techniques on how to power the controller properly in these designs. The concepts and sizing is great, but if you can't spin up the controller effectively then nothing else really matters. This is particularly important for MPPT etc. where you have a battery and solar and you're using an STM32 as an example and you need to power it from either the solar or the battery. My previous hack has been to use a buck regulator and then hack up some sort of gate that prefers battery if available and solar if not using a fet. Would love to see a better solution or at least one that is comprehensively designed. This also applies for push/pull issolated DC/DC converters at high power.
Hey Phil - Your Videos are certainly the best for PCB- and STM-Content on YT... ... but ... for the "Not-native-Speakers" ... I think it woud be a good Idea to - ... - lass es mal etwas langsamer angehen ;-) Ich gebe zu - ich verstehe nichts vom "YT-Erfolgsprinzip" (speziell: Länge der Einzel-Clips (ja, zu lang ist schlecht, usw. ...) - aber Du bist mittlerweile schon etwas "sehr flott" unterwegs. Sorry, wenn ich das mal so anmerken muss, aber etwas mehr Gelassenheit (less Words per Second) hat auch was für sich !? ...ansonsten: Mach weiter so (bis auf den SPEED ;-) - ich hoffe es geht Dir gut und Du kannst gut Leben von dem was Du hier für uns alle machst! Viele Grüße und Danke Much Greetings and a lot of Thank-Yous 😀
Moin, danke fürs Feedback! Das mit der Geschwindigkeit ist so 'ne Sache.. stimme Dir zu, dass langsamer natürlich besser wäre. Aber ist leider ein 'trade-off' mit Videolänge, und dass es eh eine 'arbitrary playback speed' Funktion gibt. Werde versuchen in zukünftigen Videos das etwas runterzuschrauben. Gerade mache ich auch die Edits, so dass Video so kurz wie möglich ist. 😊
Your English is extremely impressive, it must be your primary language yeah? I've never heard a German or any ESL nail English so well. If so, well done!
@PhilsLab Hello Phils I love your Tutoriols i need your suggestion on how you Get your first job as a Professional PCB or Hardware Designer and how we can get our first Job as a Hardware design Engineer can you Give us some tips thanks
Great Video as always Philips! Will any video about Bi-Dirictional DC-DC Converter be uploaded near future? Take a look at this Application Note from Ti "tidt046". Thanks, Philips for these great videos!

Glad to hear we seem to be working on similar stuff in parallel 😅 Hope all goes well with your boost converter!
LMAO nice space heater you got there
Thank you for this deep dive! I would love to see a video on creating a mains AC to DC converter video. Thanks again!
As always, an excellent presentation.

Excellent presentation, as all of your videos I've watched. Thank you for your efforts.
Thanks, Paul!
I would love to see followup videos on other SMPS topologies (Buck-Boost, Cuk, Flyback, SEPIC, etc.)

I hit the like button even before watching the video!!
Thank you!
That is not every risky. The content is always high quality. You know you are going to like it.
Phil, What should we do if there is no efficency-switching frequency definition or for desired switching frequency in the datasheet?

Dc bias on ceramic caps? Thats new to me... Cool video
Hello can you post a video about ultra low voltage boost converter design and sizing?

It would be interesting to complete the buck/boost trilogy with an inverting buck-boost topology video.
Your English is extremely impressive, it must be your primary language yeah? I've never heard a German or any ESL nail English so well. If so, well done!
What are the sources for those equasions? Are they from some books or rather from eg. basic inductor formula?
Hi Phil, I always watch your videos. Can you please upload a PCB design tutorial with ESP32?
@PhilsLab Hello Phils I love your Tutoriols i need your suggestion on how you Get your first job as a Professional PCB or Hardware Designer and how we can get our first Job as a Hardware design Engineer can you Give us some tips thanks
What software do you use for getting schematics into PowerPoint?
I use draw.io
Top video
Thanks!
👍🙏❤
You can resolve the problem not designing a boost converter 😅
Not helping at all for people out there who wants to build a simple boost converter 😂
Great Video as always Philips!
Will any video about Bi-Dirictional DC-DC Converter be uploaded near future?
Take a look at this Application Note from Ti "tidt046".
Thanks, Philips for these great videos!
Thank you! Oh cool, I just skimmed through the app note. Looks really interesting and something I definitely need to try out soon.
Sounds interesting especially within the battery backup perspective. Would 2nd a vid on this
