Hello I have used 20N60 to generate spwm and it worked well 2 weeks ago
I've left the circuit and rework on it but now it doesn't allow the high frequency although it worked the last time but now the o/p is a square wave not spwm wave
In other words it doesn't allow high frequency to go
it's...
First thanks for reply
I use pic16f877a
when i generated single phase spwm there were 32 sample for sin table when i tried it for three phase each sin has 32 sample but the o/p showed that there were only 3 sample per sin
Is there any other method except editing the code ?
thanks in advance
Hello I have used Tahmid's code to generate single phase spwm without using eccp and it worked well
https://tahmidmc.blogspot.com.eg/2013/02/generation-of-sine-wave-without-eccp_16.html
how can i use this method to generate 3 phase spwm ? or how can i make phase shift 120degree
to generate 3...
Hello I need three phase inverter Microcontroller code using 180 degree conduction
Wanna generate 3 pulses periodic each is shifted 180 degree form th the other
I wanna generate sine wave and triangle wave with different frequencies and compare the magnitude of both signals
It's not important to see the signals themselves I wanna see the comparisons signals
And wanna control the frequency of both
My issue is varing the frequency of the sine wave and the triangle wave not of the same frequency and get comparison between them every time of dfferrent frequncy
How can i do this ?
I have tried to code arduino using m file but using simulink i don't know if it's available
I don't know if...
Hello
I wanna generate spwm signal using arduino but I can't set the frequncy of the carrier "triangle signale " and the sine wave which are compared to each other using Arduino mega
the image illustrates what i wanna do and code are attached thanks in advance
