Tool/software:
Hello, I have an power converter topology application taht need some ePWM configuration that I cannot figure out how to do with ePWM.
The application needs results that ePWM shall output a 15kHz pulse train 50% duty that will be enabled block multiple times during the 60Hz grid frequency.
The bult-in chopper mode for ePWM will not be adequate for some reasons that not worth to explain, assume it is not possible. Hence the actual chopping will be done with e.g. ePWM1 Time-Base set to desired switching freq and Counter Compare to result in the chopping output, fixed at 50% duty cycle. Let's call that pulse train.
Then I would need that pulse train to be activated / de-activated during specific moments. I was planning to have another ePWM e.g. ePWM11 output with a TB configure to the required frequency to eanble/block the ePWM1 chopper. OHwever it seems there is no method to connect two ePWM modules in series.
What could be done? Use CLA or DAM to implement something in that direction, understanding there might be timing issues?
