TMS320F28379D: Delfino PWM sync

john backman

Hi, All

I recall seeing one TI paper (might have just been an overview) discussing PWM synchronization, for instance when one has a Converter-Inverter system.

Does anyone know what that paper was, or have a copy of it?

Thanks

John

Hi,

Are you looking for C2000 MCU related synchronization?

I did a general search and found this - note that this application note is not directly related to C2000 MCUs.

If you are facing any specific issue or have a question related to C2000 - please post here as well.
Thank you.

No, the article was part of an overview discussing how to slave a second PWM block in a second Delfino, to the PWM in the first one via an external signal. Might have been some sort of promotional overview of the part when it came out, I did not see a reference design that related to it anywhere.

Hi,

I could not find any such reference.
But synchronization of PWM modules across devices can be using EXTSYNCIN/OUT signals.
Details of the same can be found in the corresponding device TRM - EPWM chapter.
