Hi,
I am trying to generate SPWM signal in DSPF28335 by the ePWM block. But the output signal always features a fixed pulse width which is equivalent to the "input port -> CMPA initial value".

I have never used the C280X ePWM block. Based on my experience, I recommend you change the value of Amplitude in SINE WAVE1 to an integer in [0 750]. And Bias is set at 750. Maybe it will work.
