- In this video I will show how to make a basic 50 Hz pure sin wave inverter using arduino. I have discussed the arduino code but, if you don;t want the to listen the about the whole code you can skip to [7:21]. This inverter was tested with maximum 180 W load. The waveform was sinusoidal but, the voltage dropped to 130 V. One reason for that I have used 12 V to 220 V transformer, a 9 V to 220 V transformer with sufficient current rating (~50 A) is necessary for such project. However, I am working on a project to make a 350 W inverter including automatic change over, charging, and other necessary protection features. Once it is completed, I will upload all the design files, circuit diagram, code. Thanks for watching. Please like this video if you like it and subscribe my Electro-Hijibiji. I will upload more such interesting videos.

can you suggest trasformerless circuit to convert DC 325 V from direct PV panel source to 230 V AC (assuming we loose 30% energy thus by cutting sinewave shape out from area)
That is an awesome project to make your own inverter, thank you for the video.
Thanks.
Great project love to make it 😊
Thanks for sharing the project and good description of it operation.
Thanks for your comment.
which mosfets should be given spwm, 50 Hz and which ones should be given inverted spwm and inverted 50 Hz square wave is uncleared in video and circuit diagram
Very nice video 🎉🎉😊
Can we use it as a replacement egs002 module to drive a 400 volt high voltage bridge
With a few modifications in the driver stage, I think you can.
I've tried the inverter but my output at transformer is 130v instead of 230v. I need help
Check the turn ratio of the transformer.
thank you a lot for the video man
Thanks for video. I want to ask something; I need to generate the signal (we call it the needle head signal) that appears at 4:86 at the top of the oscilloscope screen. Is it possible to generate this signal as pulse (positive and negative loop) at 20hz-600hz?
You can change the signal frequency by making changes in the lookup table and a few other things in the Arduino code.
@@Thiasotiks I wanted to ask something about the pwm seen between 1.07 and 1.26 minutes;
Can a pulse signal be obtained by bringing the negative cycle of this signal below the positive cycle? This type of pulse signal is called 180 degree pulse signal in nmr pages.
How to add 3 second soft start on the code ?
I have given a soft start of around 80 ms but you may extend it to any duration by slowing down the increament process of modulation index. However 3 s would be too long time for soft starting.
@@Thiasotiks Can you please exactly tell me which part of the code should i change to get 3 second soft start ?
Is it possible use ferrit core instead of big iron transformer?
I think you can use a suitable ferrite core transformer in place of iron core.
Link oscilloscope pc🤔
my pwms will not work because SD comes up . how do i solve it please?
SD pin is controlled by Arduino. Please check your code.
No feedback for output voltage regulation ☹️. Plz try to add that feature.
Please watch this video: th-cam.com/video/3K_q7bSnCEc/w-d-xo.html
In pdf file mosfet driver ic no is not correct it must be fan7392 not fan 9732
Thanks dear Smix for pointing it out. I'll correct it soon.
Does it work well with a load with bad power factor?
There isn't any power factor correcting feature added neither I tested with a very low power factor load. Maybe it will work nominally but you must keep the apparent load below its max tolerance.
Hi, can it handle 1500w?
No.
@@Thiasotiks What if I use 48v on this circuit
@@nhloniphoshembe4934 it works if MOSFET drain to source voltage is greater than 48v and transformer is 48 volts.
Is dead time insertion in the basic code?
Yes. There is dead time in the gate pulses.
Great
can you programm esp32 for spwm inverter with tri level technique?
Since ESP32 has two 64-bit general purpose timer counters and they support interrupts, you can surely generate SPWM but, I have never tried it by myself.
@@Thiasotiks i have already a programm for esp 32 spwm inverter ,it works now in my laboratory,and it is in test stage.. but it have a weird problem ...i would like to share with you in a video,what is going on with that,if you like too..
@@oropeiro Sure, I am also interested on it.
@@Thiasotiks Give me your E mail..to send you inbox..

Admin..Pls can you upload 60a mppt solar charger for 12V,24V and 48V using atmega328
Ajibola, I have plan to design MPPT charger but, right now I'm very busy with my PhD career. So, I'll definitely upload once I get some time.
You are so cool 😎
Can we use 06n02c MOSFET
Yes you can but, I wouldn't recommend. Because it has a low max drain-source voltage rating.
Thank you sir
খুব ভালো লাগলো । ধন্যবাদ 👍👍👍
Apnakeo onek dhonyobad.
Kindly send me this circuit diagram sir...
It's already there in the video description.
স্যার আপনার ঠিকানা কি বাংলাদেশে
Na. Ami bharotio bangali.
I want to do a business with you
What kind of business?
You are far knowledgeable in electronics and in inverter too. I love your work ❤ ❤
Upload the updated version
Yes. I'm waiting for the PCB. Once it will reach from the fabrication house, I'll make the updated version.
hello, i'm has read your code for this vidio, in your code the lookup table make with matlab, how to make the lookup tabel with matlab ? can you help me sir ? thanks
HELLO FRIEND, IT WOULD BE KIND TO MAKE THE SPWM AT 60HZ ALSO BECAUSE IN MY COUNTRY COLOMBIA 60HZ IS USED THEN I WANT TO PUT ON A DESIGN I WAIT FOR A RESPONSE THANKS.
FAN9732 (IC ) NOT Found in protus where can I find it
thanks
How can we change the spwm frequency from 7 kHz to 20 kHz which part of the code should we change
Can we Can we use it as a replacement egs002 module to drive a 400 volt high voltage bridge
Yes you can, but there would be some major changes in the code. For example, in the look up table, interrupt service routine etc.
r u from bangladesh. i can guess from ur English accent
No. I am from India. West Bengal.
شكرا
Good nice work
can we generate pure sine ac supply using arduino if so how plz explai?
That's what I explained in this video. 😀
you have 60hz
can you send me circuit diagram about H-Bridge for driving inductive load l
Is it tested?
Yes. Tested.
Nice ... sir how can I contact you .
Any time through my email: electrohijibiji@gmail.com
the code plz , as it isnt avilable in the link at describtion
and its Wonderful explanation
The code is included in the zip file the link of which is given in the description. Please find the file with .ino extension.
Thanks, hope to have the upgraded version
The upgraded version is under test. Expecting to upload within 10 days.
@@Thiasotiks Great work!!!!!Waiting on the follow up video...
This is a nice and simple project. Well done. I have been working on an similar inverter for my channel.
