Hi, I want to synchronize;

the EPWM1 (master) - EPWM2,

the EPWM3 (master) - EPWM4, and

the EPWM5 (master) - EPWM6 modules and apply a phase shift in the f28335 DSP. How can I achieve this?

I can synchronize

the EPWM1 (master) - EPWM2,

the EPWM4 (master) - EPWM5, but I need one more EPWM pair. f28335 don't have this feature?

Hi Cagdas,

This is the current synchronization scheme of F2833x. You can synchronize EPWM1 - EPWM2, EPWM2 - EPWM3, EPWM4- EPWM5

Would that work for your configuration?

To get synchronization you can follow the method in Example 3-10 Code Snippet under the title "Controlling Multiple Buck Converters with Same Frequencies"/

Best,

ohh I didn't think using the same module for both sync in and out. thanks, I will try it.

Best regards.
