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!
