Hello TI community,
I would like to use the HRPWM module for my project. Using the available examples, I could implement this. Unfortunately, I have a small issue when I include deadtime. The dead time is not applied to the signal if I use complementary signal for ePWMB in HRPWM (SELOUTB.HRCNFG register = 1). Without HRPWM module, the dead time works well and also when I use normal output for ePWMB signal in HRPWM (SELOUTB.HRCNFG register = 0). Is it not possible to realize simultaneously deadtime and HRPWM in both ePWMA and ePWMB?

Yoga,
thanks for your question! F28069 operates the same as F28035 described in this post: https://e2e.ti.com/support/microcontrollers/c2000/f/171/p/712173/2624798#2624798
If you switch to a newer device like TMS320F280049C then you can apply High-resolution to both A and B channels. This device also allows you to implement a high-resolution dead band.
