DIY Inverter tutorial - Arduino or 555

Thanks to JLCPCB for supporting this video.

In this video I show you how a very basic inverter works, how to build one using arduino adn also using a 555 timer for the square signal. We obtain 220V AC from 12V DC voltage. The circuit is low power so don't use it with high tech adn power electronics. It is perfect for mobile and laptop chargers or low power light bulbs.

I hope that you enjoy this small tutorial. It is very basic.
Thank you very much!

The way that you explain it is simple and amazing. Found you in a GreatScott comment, instantly subscribed, and as we speak it is my duty to view every single video of yours. As an electronics hobbyist, you make my LED glow. Greetings from Romania!

Next time try full bridge inverter circuit.🙂

Hey, nice video as always! I like how you always add graphics to give the viewer a better understanding of your progress.
What I missed in the video is the lack of information and importance about the flyback diode.

Also, to simplify the arduino circuit, you could replace the IRFZ44N with IRLZ44N, they are logic level MOSFETs and can be controlled directly by the arduino itself. You wouldn't need the BJTs anymore.

Have a nice week!

Beautifully explained! Adding a Schmitt trigger at the output of BD139 would give a precise square inverted signal.

You're very brave touching the high voltage output.

really love the 555 inverter with the BJT.. seen this video a few times now but still love it..

[Ziplock]

7:50 Looking at the data sheet for the IRFZ44N, the Vgs(th) to turn on the MOSFET is only 2v so an Arduino should be more than enough for this without a transistor.. what am I missing?

[Elitesniper]

What could make it better is also output feedback for higher loads so it changes its input for that, great video like always

[keithking]

You can make the 555 provide a sine wave with some extra little circuitry. Or even a triangle wave!! Brilliant vision of an invertor and a class video... I will be making this now... thanks.

Very cool thx, clear explanations. I don't know if it's that specific design that I will build, I still need to study up some more about the subject of inverters, but I need an inverter and I sure ain't gonna pay for it 😂

I'd gladly share the video with my friends, unfortunately I fear that none of them would be interested 😅

9:17 Using the delay function for accurate timing is not recommended unless you turn off background interrupts and other background processes on the Arduino. You might get away with it, but for the sake of a few extra lines in Setup() it's better to do it that way :)

[vishvakumara]

You could add some delay between switching from one FET to the other - so that there is some time with no current delivered to the primary. This way you can get a modified sine wave.

What about IRF3205 (better than IRFZ44)? It will get less hot!
And for the pull up resistor, it's better to do the opposite with pull down resistors and PNP BJT, because if the oscillation circuitry fails then you completely kill the mosfets!
You also didn't talk about reverse diodes to get rid of the inductive spikes, but that is a very important point and you used them!
Finally, seeing the output waveform of the transformer on the oscilloscope seems quite impressive, given that those transformer use to work with sine wave! I would expect some distortion while using them with a square wave!
Otherwise i would say good job and i am going to build my own from a 200W transformer inspiring myself from your circuit!

Awesome dude ur explaination process is very friendly . I love Ur chanel . plZ make video on mini drone with Arduino and coreless motors.

[bxeagle]

When we have greascott and electronoobs

Its awesome

[scroft]

Awesome! Always learn something new and very informative video. Great job!

[DIYwithBatteries]

A Complete and perfect Explaination i never saw like this before. Really great Sir. 🤓👍 keep up the good content this is going to be great Sir.

[rajutharigoppula]

Great explanation each and every component in the circuit

[kedarprabhudessai]

Awesome video like as always 👍👌👌. Btw... JLC pcb is everywhere these days from great scott, electronoobs ... Everywhere 😃..
