@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.
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.
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.
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.
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
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.
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.
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 😊
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.
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.
@@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 :)
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..... :-)
@@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....? :-)
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.
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.
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.
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.
I want to make a micro analog linear servo motor........but there is no link or code......plz make something like servo.....with photoreflector and motor driver.......... that can I control with transmitter Roll pitch or yaw....
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
Dear Sir, Can we convert LED Flood Street Light's non-dimmable driver to dimmable driver 60 voltage and 1 Amp DC to DC buck converter concept? When I'm trying, but the LED Flood Panel is flicking. Please give me any solution and thanks 😊
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.
when we pressed the button ,output is less then pot_value so pwm should be increased . but in the code it is decreasing. is it wrong or am i missing some thhing ?
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 👍

Why are you used a transistor ?
and Do we need used a transistor with a mosfet in boost converter ,if yes why ?

How would you go about getting more stable control? For example +/- .001V and .001A
Absolutely fantastic
can i use volt and current control (both codes) in same circuit ? like mppt?
when we pressed the button ,output is less then pot_value so pwm should be increased . but in the code it is decreasing. is it wrong or am i missing some thhing ?
How mutch can a arduino be power externaly in the Vin pin ??

With a 555 timer you have a voltage divider on the inputs feeding two comparators that are driving flip flop.

Thanks for posting these, very educational 👍
Thanks, I like it and I'm learning, my question is, how works a constant Voltage with Current limiter
Is there any risk of self-oscillation in the constant voltage circuit? At what load frequency would that be?
10:48 Is it correct ? Wouldn't it be if voltage > output
Pwn =pwn +1 ???
Ok is it different because of the second transistor?
You must use a 5V zener diode across the voltage divider output, to protect the Arduino input from getting damaged.

i want to 10 uA constant current circuit. Is it possible with this circuit . Thanks
Sir, would you please add short protection function into this power supply. Thank you.
Aren’t there custom ICs that can do the job of the arduino in this project? To my knowledge they’re considerably faster too. Good job though!
Yes, but in this case its just a part of unfinished project.
Add a rotary encoder to control the current and voltage.
hello good video, but why my mosfet it is not switching?
Great video as always. How's the nixie watch project going?
I've made the PCB but haven't received it yet...
Isn't the high side pmos backwards in your illustration?

i want to design constant AC voltage (12V or 24V) power supply from 220/240 V, please help me
you should give an explanation about the power rating of inductors and other components
Please add simple mosfet driver
We can use a 555 instead of Arduino Good stuff mate! 👍
No, you can't
No feedback
I think you could set up a resistor divider to influence the 555's resistors that controls it's waveform.
@@TheRainHarvester You are right Dude! we can add a transistor & few resistors on pin 5 of 555ic for feedback !
