You all have good questions, I'll try to answer them soon. Thank you so much! Join my Spanish Arduino Course: bit.ly/3ldW6kO

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

[@ELECTRONOOBS]

@@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 :)))

@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 KZbin.

[@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.

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

[@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. Your explanation helped me understand what it might take to fix my rat’s nest.

[@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 😊

[@usmanumer9871]

u always explan clearly

[@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.

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.

For me this is one of best explanation on CV or CC source. Sir, can you make a video on MOSFET gate drive circuit.

Also can you recommend a good textbook to study electronics.... Thank you in advance..... :-)

You must use a 5V zener diode across the voltage divider output, to protect the Arduino input from getting damaged.

[@neail5466]

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.

[@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.

[@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 👍

[@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.

[@DIYwithBatteries]

We can use a 555 instead of Arduino Good stuff mate! 👍

[@alejandroperez5368]

No, you can't

[@michaeld9682]

No feedback

[@TheRainHarvester]

I think you could set up a resistor divider to influence the 555's resistors that controls it's waveform.

[@DIYwithBatteries]

@@TheRainHarvester You are right Dude! we can add a transistor & few resistors on pin 5 of 555ic for feedback !

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.

[@mohamedsayed-id7wd]

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

[@TheRainHarvester]

It seems like the voltage could be too high for a few loops before the pwm is decremented to the correct value.

[@BFC24]

can i use volt and current control (both codes) in same circuit ? like mppt?

[@prathambumb5593]

Excellent content 👍

[@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 :))

[@danielakintola8000]

Hello. Can it be used for AC current too?

[@galanonim3122]

10:48 Is it correct ? Wouldn't it be if voltage > output Pwn =pwn +1 ???

Ok is it different because of the second transistor?
