Problem witth dead band in inverted ePWM - board TI C2000 F28377S

Hi,

I'm using a board texas instrument C2000 Lauchpad F28377S and I have to generate two complementary signals PWMs with a dead band. Using the Simulink, I have option of use, for the same ePWM, the channel A and B inverted. But when I put a dead band between the two signals it's not work, I can't see the dead band in the oscilloscope. I have made the goods configurations for the dead band.

Here, the configurations of the block ePWM:

Any help will be much appreciated! Thanks!

Hi,

Please uncheck the ePWM7B pane completely as we need not configure the ePWM7B because the source for RED and FED is ePWM7A.
