LAUNCHXL-F28377S: Phase delay in PWM

Ramon Urquijo

Part Number: LAUNCHXL-F28377S

I use f28377s for modulation in multilevel inverter and i need generated a phase offsetbetween two PWM. The block ePWM in simulink have a option Phase offset value (TBPHS), but i can´t configure it correctly. I would greatly appreciate your help.

best regards.

Hi,

It would be good to post this on MathWorks forum for better response.
Please see the post below for details.

As a general answer, TBPHS is the way to achieve desired offset across multiple PWM modules.

Hi Ramon,

Here is the doc page and section on TBPHS:

https://www.mathworks.com/help/supportpkg/texasinstrumentsc2000/ref/c280xc2802xc2803xc2805xc2806xc2833xc2834xf28m3xf2807xf2837xdf2837xsf28004xepwm.html

AFAIK this works correctly, but I've never personally used this setting.

If you are still having issues, please contact MathWorks Technical Support

Cheers,
