sinusoidal PWM

[sangaboy]

Hi !


SPWM stands for Sinusoidal Pulse With Modulation.These signals will be used to control Three phase inverter.

thankx

I'm afraid the letter sequence SPWM actually was derived by Darrel for his contribution of Software Pulse Width Modulation.

That's what I thought but figured it couldn't be since we're talking about CCP-modules etc. Doesn't matter, now I know what the OP means although I've never heard the term before.

Hi
I download the pic16f777 datasheet from microchip website I go through it I found it does not much differ from that of pic16f7877 so it easy for me to shift from the PIC16877 to 16F777 which has three ccp modules for SPWM generation.

thanx

Sorry for delay in reply, now I 'm in seventh semister exam of my BSc in electrical eng.

hi to all
I try to simulator my code on IMPLAB simulator but I have not yet sussceed til now so I decide to simulator with pic 16F877 which is found in ISIS but when it comes to real environment(actual implementation) I 'm going to use pic16f777 , which I 'm waiting for it to come.

Then
can any one help me !
how to take my waveform from digital oscilloscope in ISIS cauz I want to uploaad in this forum ,I try to print but the file does not contain any waveform. I have some problem on my ouputs.
thankx.
