Hi experts,

My customer is using TMS320F28377D.

They want to get the waveform as below using ePWM.

is it possible to get the below waveform using deadband

they are first to TI C2000. please explain detail.

Hello,

You can achieve desired PWM by using deadband submodule. Please refer to the ePMW ex8 in C2000Ware for software development: C:\ti\c2000\C2000Ware_5_04_00_00\driverlib\f2837xd\examples\cpu1\epwm\

Hi Stevan,

they reviewed with ePWM ex8 example, but they did not get the waveform they wanted.

what they want is a waveform that decreased byt the falling edge deadband.

please check again

thanks

Hello,

If they want falling edge delay, they can just set it up same way it is done for rising edge delay.
