Hi,
could anyone tell me how to introduce dead band time for 10us in TI DSP processor using simulink?
I tried with period of 1000 but it is not working.

Required dead band is calculated based on the system clock frequecy. Please reffer to the TI doc associated to the ePWM module.
For example for f28335(https://mil.ufl.edu/3744/docs/TI_DSP/TI-docs/sprug04a.pdf), I have claculated the dead band as shown below:
Required dead band = 50n sec
Sysrem clock =100M Hz
dead Band = 50n*100M = 5
FED = DBFED × TTBCLK
RED = DBRED × TTBCLK
Where TTBCLK is the period of TBCLK, the prescaled version of SYSCLKOUT
TBCLK = SYSCLKOUT

Hello venkata Kumar, Can you share your Epwm A and Epwm B screenshot. I thik you are obtained just inverted Signal fron EPWM A and EPWM B.
