How does a modern Power Supply work?! (230V AC to 5/12V DC) DIY Flyback Converter!

Würth Elektronik products, which were used in the video:

In this video we will be having a look at the kind of power supplies you use every day. I am talking about switched mode power supplies that convert our 230V AC mains voltage into for example 5V or 12V DC to power our electronics. I will not only tell you all about the heart of such a system, a flyback transformer, but I will also show you how it is used in a flyback circuit. At the end I will also show you a DIY attempt of such a mains power supply that you should (please) not replicate. Let's get started!

Wurth Elektronik: Do your best
Great Scott: *Cuts transformer in half*

"Do not build this circuit! With that being said, here's the schematic" -Great Scott XDD

Great video as always!!! Ignore the YT analytics, if they still show poor results. It's not you, it's them and please don't change your style to try and appease the algorithm. . We're all here for the quality of videos you have always done and this is a perfect example.

[melchiortod]

That's like marketing to the next level! Love that!

[romanmorales]

To be honest, i learned more than i could describe from his and other videos than all the semesters i went through in university. The videos are simple, not boring, analytical and very interesting❤.
Your videos helped me become a better electrical engineer❤.

Wow, I have watched dozens of videos about SMPS before, but this one really made the subject to click.

[thebamplayer]

Can you make a video about active power factor correction, because it's an important topic with switch mode power supplies. Due to it's big capacitors.

[samim]

I am helping with YouTube algorithm, I am watching again and again. LOVE YOUR CONTENT

[The-Master-of-None]

When Scott says "RIGHT?" The answer is "NO".

Great content as always! Thanks for sharing your knowledge.

[NilsRohwer]

Fascinating, I'm very happy to have this video from you. I have wondered about Switching mode power supplies for ages, and to have such detail is great - to be fair, I'm 1:03 in, but I know it'll be good.

Edit: I was not disappointed! Thanks.

[TotallyNotJason]

Thanks Würth elektronik for us to learn more about Switch mode power supplies!

[thatoneguy]

I really love Würth Elektronik's products, and I love them even more for sponsoring you!

[L.Lagrange]

8:56 what an absolute madlad lmao. Props man

[hobbyelectronics]

The best description of flyback transformers ever :)

[FINALASTXTN]

Finnally somebody goodly explained a flyback converter

[ucan-diy]

Great work! One of the best channels on YouTube!

[MrTacoSr]

sometimes I have to rewatch these videos because I get so caught up in him writing and labeling so perfectly with no mistakes

[MrJugsstein]

I'm coming to electronics later on in life. Your tutorial have to be the clearest and most well explained. Really enjoy and get so much from your videos.

Thanks for your time.

[edoardocastellaneta]

hi, great video as always. just keep in mind that in case of flyback topology, we aren't really talking about a transformer: since there is a high reluctance gap, a flyback trasformer is more like two mutual inducitors with a very high coupling coefficient.

I have been fixing these for years by changing some of the caps..I had a good idea how they worked and you defiantly boosted my understanding of them even further... lots went into the design technically.. thanks
