I'm absolutely impressed by the clarity of your explanation of sPWM wave generation. Kudos to you, mate! :)

Best sPWM tutorial I have seen so far! Very clear and informative. Thanks. Point to note, on Mega 2560 one needs to change DDR in the variable frequency sketch for PB5 and 6 - i.e. different to Uno. So its DDRB = 0b01100000. Cheers

Perfect presentation with deep real world focused. Many many thanks for up loading and for noble intention.

*Amazing tutorial. You know the subject matter the best.*

Thanks a lot!...I implemented the same logic of SPWM on pic16f72 and its working fine. The detailed tutorial was really helpful.

I've been searching for this stuff for a few weeks now.... the best explanation that ive come across so far ! Thanks...

It's best tutorial in whole UKposts

Very cool stuff! Thanks for the well presented explanation.

Guy! I love your work!

wowww ,,,, why I just find your vid, this is best presentation- Thank You !!

Very nice! I'm now a subscriber!

very great tutorial, i learn a lot from here

At least 1 year of Electrical Engineering and half a year of master's in electrical engineering condensed into a well composed and well explained 24 minute video. Someone give this man a stool, a camera , a whiteboard and a decent salary as a teacher...because the old farts couldn't explain how water boils to a fucking kettle...

Thanks for such a nice demonstration of SPWM signal generation, can you please tell me what is the value of capacitor used in RC filter

very instructive tutorial. Thanks,

this PWM tutorial is good t , it's the 1st step to make the inverter 6PWM IGBT to control a AC MOTOR "hi power" thanks , we follow you , ok!

Very good brother, greetings from Mexico ... just one question, pin number 13 that works in the physical application.?

this is the most informative video I have found. I am curious . do you or have you made a boost stage for a inverter? or the code for arduino to drive a DC boost. it needs to be self regulating. I found a spwm driver board. to run safety functions. and drive the H bridge. my concern is boosting 12-24v yo about 170+/-, at enough current for a 2500-5000 watt inverter. from your video I think you can solve this issue. if you can. it would be a great help. I know very little a out arduino. and coding thanks

Thank you for your code, I have gotten a nice sinusoidal waveform. I will use the wave to drive the speaker and I need a circuit with few transistors to amplify the signal. Could you give me information about the circuit?

very good effort for spwm generating idea. but you should build a multi channel spwm for full bridges.

Very nice tutorial sir... I've tried to use your code (SPWM with variable sinusoidal frequency) on my single phase inverter project. But I have one question... Can you explain me how to add a "delay" (about 500 uS) in the transition between OCR1A and OCR1B? Thank you sir...

Well done mate

If i have a sqaurewave inverter could I feed the Spwm through an Opamp and feed Fets to modify output signal?

if i want to make a little inverter (low power and for 10 DC Volts) with that code, i only put the outputs 13 and 10 to H bridge with mosfet or IGBTS?

Dear sir could you please me one thing instead of H-bridge if I use center tap transformer for out put and used two sets of mosfet for pin 9 and 10, so what will happen?. sine wave can generate or not? or generate some distort wave?

Thanks for this!. Also I saw your code on github and I've been trying to add a dead band/dead time to it. Do you have any tips for this? Thanks again.

Great video !

awesome ... thanks for great information, can you explain generic spwm code more clear

hello sir, what is the value RC filter? i tryn 100nf and 50kvr not respon thank u

Hi. Is there any plans to implement this on esp32? Would be much appreciated to see example of working code on esp32 to output spwm pulses.

Thank you for this video.this video very perfect 🖒🖒🖒🖒🖒🖒

Could you please let me one thing. In arduino IDE io.h library are available?. How can I write code in register level as well as arduino function.

Is it possible to add a 90 degree phase shift in the spwm?

Hi...please tell me that can i check results of these program in the serial plotter??? Please reply..

sir please let us know the values of capacitor & resistor you used here.

can you help me, I want the fundamental frequency to be 60 hz thanks

You rock my guy

please tell ,how to calculate the value for sine table....

nice video. i converted the ino file to hex and ran it on proteus .But the output signal seems to be less than 50 hz and the line period = microMHz*1e6/freq/SinDivisions does not seem to work but if i use period = microMHz*1e6/freq/SinDivisions /8 then i get 50 hz frequency can you tell me why?

How to generate the pwm of 10 kHz in ARDUINO DUE? What changes I will have to do in your code? and how will I get the header file of look up table for the sinusoidal ,triangular and pwm ? also u have used "#include #include " how will Iget the above two ?

sir i need about ibgt details using this project

thx alot dude

Hi sir how to change the mosfet switching frequency please

good job !

What oscilloscope is being used here?

Hello my friend. How are you doing? I want to know how much is the capacitance that you used for the low pass filter. THANK YOU SO MUCH. GREAT VIDEO!

which output is giving pwm to inverter which we are going to implement ? are u using 13 ?

Hello meanman, can u help me kindly with three phase spwm.. specially the confusing part is to generate 120 degree phase shift with high frequency (40-60khz) range.. I wonder how to manage that with 16bit timers including 8bit.. please guide...

I want to program variable frequency spwm in my arduino mega 2560, but the catch is that the magnitude of the sine wave is also dependent on the frequency by the equation magnitude= (frequency*4.4 +5.4)/225.4. Is it possible to do so? If yes would you please let me know the changes that must be made in your code for variable frequency spwm? Thank you!

hello good night, I'm experimenting with a 3-phase inverter design with arduino nano, put the program that is here on the internet, but the fault that I present is that it rotates like a stepper motor, please please me you can indicate that it may be happening thank you,

Thanks for useful stuff. I am wondering if the amplitude can change? I am using encoder for speed reading when the speed reduce i need to reduce the amplitude for the output pwm. Thanks!

Very good and informative video.It helped a lot. Thanks. Do you have one for three phase?

amazing.. learnt a lot form this video.. I really appreciate your work

can you please tell me how you have determined the contents of look up matrices

So if we need for a different switching frequency , we need to change the lookup table right ? Also how to write the lookup table?

HELLO FRIEND CAN YOU PLEASE TELL ME THAT WHAT ARE THE VALUES OF R & C YOU USED HERE. I WILL BE GLAD IF YOU REPLY. THANKS

I think that using analogWrite command is simplest to get the same result

Hi. Meanman from your code is possible to adjust the output voltage. I have transformer 10v 0 10v input 12 volt with no feed back my AC looks good on scope butt under load i get 207volts. can you help in anyway , thanks Yannis

How can I download your code, and what are the libraries needed Engr. Kurt?

Can you help me with my custom game pad? I have some pics of what I'm using if you would like to help. I'd really appreciate it. I don't know how I can wire the button board to my computer

can you make another video using pic18f4550 using MPlab compiler for the spwm?

Bro how to generate 3 phase pwm supply

Nice away some can you make video for three phase spwm 120 apart from each other

for 60Hz have any modification?

And sir should we make spwm for sinwave without intrupt

how can i increase two signal's gap and how can i add feedback loop Please help me sir!!!!

May I know how do you calculate the lookup table?

Sir i used analogread() command in isr(timero_vect) after that my circuit is short and output is out shape sir kindly how i can use adc in isr(timer0_vect)

Where can I learn how to do all this from scratch?

please can you say me the value capacitor, resistor and trimmer? thank you very much.i don´t speak english very well

Hi sr. Nice video,mmmmm.... please, can you tell me how make it for 60Hz?

hey can some body help me here. I'm new in arduino. So i want to ask that why the ground pins of arduino were not used ?

Me: Spending weeks figuring out the best way to make a perfect SPWM output. Other UKpostsrs: Writing this code " int mos_top = 3; int mos_bot = 5; double pot = 0; void setup() { //define the pins as outputs Serial.begin(9600); pinMode(mos_top,OUTPUT); pinMode(mos_bot,OUTPUT); pinMode(pot,INPUT); //Initial value is LOW digitalWrite(mos_top,LOW); digitalWrite(mos_bot,LOW); } void loop() { double pot_val = analogRead(pot)/10; //One is LOW and other is HIGH digitalWrite(mos_top,LOW); digitalWrite(mos_bot,HIGH); delay(pot_val); // 1/16ms = 62.5Hz //One is HIGH and other is LOW digitalWrite(mos_top,HIGH); digitalWrite(mos_bot,LOW); delay(pot_val); Serial.println(pot_val); } " and putting "PURE SINEWAVE INVERTER TUTORIAL " in the thumbnail.

hiiii.nice explaination.can i get ur email id please.as their is some important issues that i want to share with you related to my project.
