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

I noticed the overvoltage, too, but didn't consider damaging humans ... Now I will add an artificial load if nothing or not enough is connected at the output. Thanks for pointing out the problem!

Do you have any plans on covering multiphase buck converters?

That's why all bug converters always have an LED at the output. To ensure a minimum load.

Very interesting tutorial. Do you use 2 MOSFETs because of power management?

Keep doing

A subject could only be explained so beautifully and fluently. Thank you.

@ElctrArc240 can you please make a full video on designing variable power supply which can control voltage and current upto 30 volts and 5 amps with feedback signal so that on applying load voltage doesn't drop

Voice🎉❤speak ❤🇧🇩

Very great job. The only problem is my head stopped working 👀

You need to be recommended by eevBlog 😉

How can you explain the circuit without schematic

I love you❤

I didn’t learn as much in engineering as I am learning from you…
Thank you for the contribution to the world of electronics.

Nice video. What power meters did you use?

There so much great information packed into this episode, I am going to have to watch it another time to make sure I understand everything. Thank you so much for the work you put into this.

Shouldn't the mosfets and diodes get their heatsinks installed?

Thanks a lot and we would like to see a video on the common compromise btn good cooling and good electrical layout

would you give us a detailed design and test for a Buck converter that takes 80v and step it down to 12V 30A
many thanks in advance

I'm not designing a DC-DC converter. But rather a switching mains current limiter. (Dropping the voltage to maintain the current below some threshold.)
Your video was very very interesting. It highlights a few things I should pay attention to.

Props 👏

Your videos are great

my bad english and terrible setup will never get any views

Your analysis and explanation here is very good. One note: I design integrated switch-mode power supplies, and we absolutely do use boost regulators in the discontinuous region (mostly for light-load switching efficiency). This is okay because in real-world applications, duty cycle is controlled in a closed loop to regulate to the desired output voltage.

The accent is not for me, but the video is😢

😊

Sir thanks a lot.I am producing 2 microampere and 15 voltage ( rectified) from piezo electric devices. I would like to amplify current like ( 15 microampere) and two 2 volt ( power conservation), how do to it? These buck dc dc converter works for this range current?

Awesome way to explain difficult things and demonstrating with real stuff.... Hat's off to you,.........

And pass an exam I will



...hopefully.

Hello, in what way is it possible to calculate the release of heat on the inductor in a pulsed scheme?

Thanks!

I'd like to learn how to make a breakout board to see all the signals you made, I don't ask for a schematic but a lesson on how to design your board, what to consider, and how to sample these signals to visualize on the oscilloscope. will be great to know. thanks.

So much info packed into this video, I love it
If I can give some feedback, when looking at the scope in the calculating inductance section, I started to get lost about what we were looking at until rewinding to remember what you said it was. Maybe if you could go back and edit in a couple text boxes for things like “boost converter inductor voltage” it would help keep it straight

Cool stuff bro! Are you going to release your converter design files somewhere ? It would be really helpful for those who are learning and get some hands-on testing experiences on the real cirucit.

Thank you very much for creating such interesting and easy to understand explanations for all the themes you cover! That's a treasure for every electrical engineering student.

That reduced capacitance when charged bit me once. I ended up doing an easy/expensive swap for tantalums. Grr.

you are god

Greatly explained!! I'm not surprised you got hired at redbull powertrains, hopefully in 2026 if NDA allows it i would love to hear your take about previous hybrid f1 engines and the clever ideas like the mercedes split turbo.
Anyway, informative video as always, keep it up! : )

Why aren't you at a 100k sub yet!? Love your videos. Keep it up

This video is amazing! It is more relevant for real world applications than my lecture about power electronics AND high quality.

When I try to simulate a boost converter in falstad (circuitjs), it somehow never works and I can get only around 500mW on the output. (5V->9V). I idealized the diode to a forward voltage drop of 0.1mV ... and varied clock frequencies, duty cycle, Inductor and Capacitor values - but at a load below 1kOhm, the voltage breaks down and even with my nifty PD controller, it never returns to 9V. (controller sets duty cycle (and a bit frequency) D from 0.25..0.75. Something is foul ... or fishy... or both...
If I replace my controller with a fixed pulse voltage source with 0.44 D, it looks the same - voltage drop on output etc.

Did any of you guys try to simulate a boost converter with falstad? What is your experience?

This is so insanely well made and easy to follow! Thank you for your work!

This channel is a true gem, truly awesome videos!

Excellent, it reminds me of old school British educational videos.

Why don't you derive the Vout/Vin equation from 1st principles ? Then we can understand the different operating regimes better !

Your channel is insane

You are excellent in going into detail for those "simple" circuits. This is perfect for beginners to grasp what is going on and even seniors enjoy your take on those topics.
