The foliowing program not able to produce PWM wave

//long pulse_variable1=0; pulse_variable2=0; pulse_variable3=0;
long EPWM6_TIMER_TBPRD=5000;


time_counter++;
if(time_counter>=200)
{time_counter=0;
}

angle_A=_IQ16(2*PI*pulse_counter/200);
// angle_B=_IQ16(2*PI*pulse_counter/200+_IQ16(2*PI/3));
// angle_C=_IQ16(2*PI*pulse_counter/200+_IQ16(4*PI/3));

phase_A=_IQ16mpy(_IQ16sin(angle_A),_IQ16(.8));
pulse_variable1 = _IQ16int(_IQ16mpy(phase_A,_IQ16(EPWM6_TIMER_TBPRD/2))) + EPWM6_TIMER_TBPRD/2 ;//3.016712
// temp_variable1 = _IQ16int(_IQ16mpy(sin_out,_IQ16(EPWM6_TIMER_TBPRD/2.353))) + EPWM6_TIMER_TBPRD/2 ;//3.016712
EPwm6Regs.CMPA.half.CMPA = pulse_variable1;
