SImulink of adc -pwm with tms320f28335

I am learning the TMS320f28335 experimenter kit with matlab. So i made a simulink with ADC, gain and epwm. I am varying the dc voltage from signal generator from 0 to 3 volts, but the width of the pulse is varying from 0 to 50% only. Help me sir.

Dear Mohith,

You need to send a sinusoidal signal to PWM block then by changing the amplitude of the sinusoidal signal the pulse width will change
