Una pregunta, si nos apuntamos al curso ahora podremos seguir con el segundo curso avanzado o ese curso ira aparte? A mi me interesa mas el avanzado, pero si va todo junto me apunto ya y asi ya lo tengo. Un saludo
@@09iban09 hola. Los cursos van relacionados pero serán dos cursos por separado. Quiero decir tendrías que pillar el segundo también. Si quieres espérate al más avanzado. Saludos :)))
@@ELECTRONOOBS vale perfecto gracias. Esperando al segundo curso con ansia =D
@HalfSpeedMastering hi bro. Im looking for some budget 300-350v (working voltage on the system 210-260v) mppt, but they all priced around 1000$. Where is something cheaper on the market? I love vectron, but does not have that much cash right now... I appesiate your advice.
As Albert Einstein once said, you made everything about buck converter as simple as possible but not simpler than what it should be. Great video man! It's really an interesting time to be live in because video tutorials of this quilty are freely available on TH-cam.
I ALWAYS WANTED A VIDEO BASED ON THAT!!! Good Job!
best arduino project th-cam.com/video/zxlb22cTwHo/w-d-xo.html and you can also get code from this video
Very well explained. A little more detail on the role of the inductor and diode: When the switch is closed, the supply is charging up the inductor, which stores its energy as current. When the switch opens, the inductor discharges its energy while pulling additional current through the diode. This is what allows the converter to output more current than the supply (unlike a linear regulator) and thus be more efficient.
I love how you explain stuff into details. Glad to learn from your channel as always. Great video
Great vid! Was working in a synchronous version lately, very timely :)
My three favourites are electronoobs,Techbuilder and great scott
@@ericdenny4515 same here
Fantastic overview. I’m looking forward to understanding the code that makes this work.
Great video man, awesome breakdown from the very beginning and showing the fundamentals behind the circuits! Too many channels skip over the educational information, 👍🏻. Definitely looking forward to the future MPPT controller. Well done, sir.
Nice video! Love them not just the way you present them but because they teach and clarify some vague concepts. Thank you!
Your videos helped me alot for my engineering project
Absolutely worth my watchtime.🙏 Thank you for sharing. Good luck 👍 for the next one
One of the best explanation i have seen for a long time. You need really know your craft to explain it in such simple terms. Its never easy explaining complex thing very simply. Well done look forward to watching more
I've watched your videos for serveral months. Great explaination in simple words, although I'm not a native, but still can understand easily. Thank you a lot.
This guy is one of the best of the electronic enthusiast TH-camrs. I have watched the channel grow quite successfully. Shame about the constant ads - I pay for TH-cam and expect an ad free experience.
Excellent absolutely excellent coverage of a buck inverter based on Arduino. Looking forward to the full MPPT project.
Thanks for this video. I have a closet full of low power gear, most 5, 12, maybe 18VDC - many of us do - and it’s long frustrated me that every single device needs its own 120VAC power input. It’s messy wiring, requires multiple 120V power strips, and I have to guess can’t be power efficient doing AC to DC for each thing. Your explanation helped me understand what it might take to fix my rat’s nest.
I've been wanting to do this for a while
Realy great job!!! You won a subscriber, thanks for your efforts
Two seriously COOL ways to use an Arduino! Thank you for explaining it all in such detail. Super!
ohhh your channel is definitely under-rated crystal clear explination.
Good. Thanks for fresh content Everytime
Excellent work! This will be taught in the school where I work (referring also to your video and video channel) adding PID control. Thank you!
"taught" not "teached", dreadful grammar for a Teacher.
@@stephaniesadie832 thank you. I teach electronics in Italy
Your channel has lot of good stuff, so i'll subscribed it..,, keep growing good content.
Thank you, great explanation!
Thank You So much for Great Tutorial 🔥🔥
Thanks for making MPPT CONTROLLER 😍
Happy holidays, this Buck's for you, buck converter!

great video, and clear explanation ! 💖💖💖💖💖
Very nice video!! Good job!
u always explan clearly
Thanks one more time again for the detailed but simple in explanation video for electronics . i have learned a lot and helped me build my own projects.
Thank you!
@@ELECTRONOOBS Hey, I also think this video explains very good how the converter and module are working, but you could please post the code for using buck converter and current limiter at the same time? I don't know how to program it... Thank you very much :)
Waw, really usefull and a great video. Very well explained !
Happy holidays and keep it safe !
Thank you very much! Happy holidays to you too!
Great video. Please make a video on how to add PID control to this converter.
damn waiting eagerly for the MPPT video, This channel keeps getting better every video.

Great vídeo man 👍👍👍
Always Great Tutorials 🔥🔥

i am waiting for next week updation of this project. keep doing
Suggested to add inline capacitor with gate and appropriate resistor to Source to limit pulse-length to the Gate. This is common practice to block DC. That way, it would not matter if your MCU or driver circuit failed to a DC state. The MOSFET Gate would only respond to pulses. the RC forms a high pass filter. The inline Capacitor to Gate introduces ~90 deg phase shift, but not a problem if you only have one channel or drive all Gates the same way.
Great.... mppt 3 stage charging...
Well explained 👌 Good 👍
Great tutorial. Excellent...
Great video
Thanks for sharing :-) 🎄
Absolutely fantastic
fantastic project
Very good video. Would be nice to understand how to calculate values for inductor and capacitor.
Wait for it bro. love you
Awesome content 👏
Great video!!
Could you please explain how to calculate the inductor value in the buck converter?
Great video bro.
There's a highly linear relationship between the pwm frequency and the voltage output, so you could probably calculate an accurate offset to add to or subtract from the pwm frequency in a single loop, instead of adding or subtracting by 1 with each loop 😊
No, depende de muchas cosas incluida la temperatura, no es una cuenta Lineal
great video!
great video. suscribed
Hey, great video! Could you give us a schematic and code for using the buck converter and current limiter simoutanlisuly?
Excellent content 👍
Good video!
Thanks alot, Will need to build a buck converter in my upcoming project. How do you calculate what exact inductance/capacitor values necessary?
thanks brother you are the best god protect you
Very nice project
I know
nice concept
very great, thanks
Nice work, great explanation, well presented. I also liked that you have melted your solderless board in spots. Shows you like to experiment (and maybe failed, ha). Thanks from Colorado.
Yes I fail a few times till I get it right :)
@@ELECTRONOOBS All the great engineers fear not their failures but embrace them.
You are excellent in explaining ❤️,
This is a great video for understanding the theory but a cc cv module from china would be pocket friendly.
Great Job!, Please Make a video for PID controller large heaters(like 1.5kW) using SSR, Thank you.
Keep going!
thanks for sharing
That's my stuff 🐱. Keep it up
Thanks, I like it and I'm learning, my question is, how works a constant Voltage with Current limiter
great video,please make a 48v arduino esc
Hi
Just a question. The p-channel FET at 6:01, does it turn right? You also have the parasitic diode in the FET that will conduct. As I see it, it will conduct when the FET is OFF. Also tuning the FET would leqd to a more defined ON/OFF voltage.
Hello. Can it be used for AC current too?
Hi. Great video for beginers. Please correct you video for errors in schematic. Your P-MOS transistor has swapped Source and Drain (in for example 5:52). Always connect Source of P-MOS to power supply and Dran to your load in this configuration. Otherwise you tranzistor will be still open thanks to body diode.
Thank you 🙏
For me this is one of best explanation on CV or CC source.
Sir, can you make a video on MOSFET gate drive circuit. Most of us confused when to use driver IC, when to use isolated transformer, also many schematics offers discrete bootstrap circuits, so can you explain which option is efficient for specific circuits.
Also can you recommend a good textbook to study electronics....
Thank you in advance..... :-)
FYI, greatscott made a video a week ago about driving mosfets. That video helped me understand it very well
@@eindeend Thank you, and I'm also his old subscriber, still we may get new suggestion or even detailed explanation or different opinions from Electronoobs, 2 is always greater than 1 right....? :-)
Great video as always. How's the nixie watch project going?
I've made the PCB but haven't received it yet...
Great explanation of how the feedback loop can maintain a constant voltage output. Awesome video sir!
Is there any risk of self-oscillation in the constant voltage circuit? At what load frequency would that be?
This is gold
Good job
Brilliant !!
awesome !!!
Great vid
Nice but ...
With a 555 timer you have a voltage divider on the inputs feeding two comparators that are driving flip flop.
Wouldn't it be simpler to substitute the arduino with a 555?
I haven't drawn it out but I'm guessing less cost and components without the risk of burning out your microcontroller.
Update.
I just watched your video on the Buck converter and read your post on using the 555.
Nice to know I was right about it being possible.
Thanks for posting these, very educational 👍
This was great! I just wish you could make a arduino buck boost converter with current limiting too. Pleeeeeease!!!
Is the diode placed at the best place? Because once the switch is off, the energy stored in the inductor would push towards the same direction as when the switch is on which results a voltage spike (inductor engergy + capacitor energy). That voltage spike would result a current firstly pass through the LED and then the diode. By the time the current reaches the diode (if it does), the LED is already burnt. This indeed saves the MOSFET but destroyed the load which I think is much more expensive than the MOSFET. I suggest to put that diode together with the inductor parallely just after the switch and befor the capacitor. In this way the the diode is freewheeling immediately after the switch is off.
Hello I need a constant voltage in a buck converter no matter the load but I use lm393 to regulate the current but i can’t get the voltage to stay at 24 voltage the voltage drop to 20 volt I use feedback to the comparator but I don’t know how to use op amp to get constant voltage or I have to use programming ic to do this because op amp cont do it
can i use volt and current control (both codes) in same circuit ? like mppt?
How would you go about getting more stable control? For example +/- .001V and .001A
you should give an explanation about the power rating of inductors and other components
If you open the switch, the coil will try to keep current flowing. This can be done through the diode in the capacitor. With the switch open, the coil becomes a battery for a short time.
The diode should be a fast Shottky diode, not a slow 1N400x. A quick UF4004 work.
Sir, would you please add short protection function into this power supply. Thank you.
i want to 10 uA constant current circuit. Is it possible with this circuit . Thanks
Very nice 👍 video.
You show high side switching in the schematic. What is the device used in the setup shown.
Mppt charge controller was my university project
Exelente diseño!!!, el circuito de control del mosffet variaría sin en ves de un canal N pongo un canal P??
Add a rotary encoder to control the current and voltage.
