@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.

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.

Excellent absolutely excellent coverage of a buck inverter based on Arduino. Looking forward to the full MPPT project.

[@ecospider5]

Fantastic overview. I’m looking forward to understanding the code that makes this work.

[@mrfrozen97-despicable]

Good. Thanks for fresh content Everytime

[@superpuppy7854]

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 👍

it needs PID to be better :))

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....

[@marshdilruk]

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 KZbin.

[@srijantanwar3245]

i am first love you bro

[@ericcmcgraw]

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.

[@abdullahalrazi3491]

Thanks alot, Will need to build a buck converter in my upcoming project. How do you calculate what exact inductance/capacitor values necessary?

[@asitsantra3491]

Great.... mppt 3 stage charging...

[@azyfloof]

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 😊

[@michaelfeeley4351]

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!

[@pashko90]

Yes, but in this case its just a part of unfinished project.

[@RinksRides]

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.

[@electronic7979]

Helpful video. I liked it

[@iuhere]

Absolutely worth my watchtime.🙏 Thank you for sharing. Good luck 👍 for the next one

[@linuxromania]

Hi. While the project is good enough for usual loads, i wont recommend it for RF. Arduino aint real time so when extra load is present the code will delay pwm increase. That delay will make output voltage to drop untill pwm is increased and so on looping. That behaviour is seen in your video where output ripple increases, ripple which generate big RF noise.Great project anyway, congrats.

[@IncroyablesExperiences]

Hi! I made an equivalent project years ago in order to charge CC a SuperCapacitor (efficient charge) and get its energy back at CV. I didn't managed to implement a full PID regulation and I see you don't tried (I was expecting as you've done many PIDs before ^^). Your regulation is a kind of integral only (and not proportional to the error). Do you think it's possible to implement a full PID this way? It's easy when input/output are not quickly related (heat control, drone axis, etc.) but here a proportional or derivative reaction would instantly fail. Have you tried? Thanks to be the only guy on the net that could understand this issue 😌

[@piiumlkj6497]

I think he kept it simple so the majority of viewers can understand, maybe you can do pid on your channel , défi ?

[@IncroyablesExperiences]

@@piiumlkj6497 He often is exhaustive, I'm pretty sure he tried and conclude it's not possible, I think the loop frequency of the Arduino isn't fast enough to really be able to manage a functional proportional (and worst derivative) effect (it's an assumption).

[@IncroyablesExperiences]

@Electronoob?

[@raghavsrivastava2910]

Great video. Please make a video on how to add PID control to this converter.

[@hodissergiu8883]

A buck converter for an mppt system is a poor choice because of the way it works. You either connect the convertor to the panel or disconnect it (when the mosfet is open) resulting in power that was not transfered from the pv array. An boost, sepic or cuk would be better suited.

Great video as always. How's the nixie watch project going?

[@ELECTRONOOBS]

I've made the PCB but haven't received it yet...

[@raagamparmar179]

2nd view!

[@simengfu7352]

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.

[@ayman_khuzundar]

Good video, I just wondered why are you connecting the MOSFET like that? you must achieve a Vth between the Gate and Source which is about 10V, but when your output goes up to 15V -for example- the Vgs will be 5V -if yoy apply 20V at the input- because the source isn't connected to the GND but to the Inductor! you have to use a gate driver IC

[@ayman_khuzundar]

OMG ! it is a P-MOS but the schematic shows the source connected to the Inductor and the drain to the Input, you just have to flip them :))

[@jensschroder8214]

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.

[@thomassorensen7907]

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.

[@ritzayrton4649]

hello good video, but why my mosfet it is not switching?

[@rjhornsby]

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.

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.
