Phase Shift Of 120 In Program Using Output Compare Instruction

India

Hardware: DsPIC33EP256MC202 Microcontroller Software: C Programming Using Xc16 Compiler And MPLAB X IDE Software

sir,
I am working on the above mention microcontroller to build a program for three phase three level inerter but I do not getting the idea for how I can get the pwm pulses for inverter using output compare with 120 phase shift

Program

#include "gioref.h"
#include <outcompare.h>
#include <xc.h>
#include <libpic30.h>
#include <math.h>
#include <stdio.h>
#include <ports.h>
void Delay_us();
int a,b,c ;
int main()
{
    PLLFBD=46; // M=48
    CLKDIVbits.PLLPOST=0; // N2=2

Are you able to generate single sine wave? I think you should first generate single sine wave output with desired frequency successfully. Have it checked by an oscilloscope. Then only move to generating 3 sine waves with phase shift.
