F28335 ePWM inverted signals

Pieter Gervoyse

Hello,

I'm using an eZdsp F28335 + Simulink to generate PWM signals.

Whatever my settings of the c2000 ePWM-block in Simulink are, I constantly get the same signal on ePWM1A and ePWM1B. How can I generate a signal on ePWM1B that is the inverted signal of ePWM1A?

Thanks in advance,

Hi Pieter,

In short you want ePWM A&B to be complimentary of each other right? I don't know how to do it with help of Simulink but yes with help of CCS C code I can guide you.

Hi Gautam,

Thanks for the answer. Yes I want ePWMA and ePWMB to be complementary of each other. Unfortunately I am programming this in Simulink, so I think you can't help me.

Yup, I won't be able to help you out. Just be patient as simulink support on this forum is very limited and so it might take time.
