Which Module or sub-module of ePWM should I use

Other Parts Discussed in Thread: TMS320F28035, CONTROLSUITE

Hello,

I am working on designing a digitally controlled full-bridge Inverter with "TMS320F28035 Isolated controlCARD".

Basically I want to achieve a sine wave output with 60hz and 30 VAC.

I went through the enhanced pulse width modulation documents for F280xx and I understood that there are eight different modules and some of those modules has sub-modules.

I really want to know which module should I implement. I also wondering if there are any resources which explains ePWM examples provided by ControlSUITE( i.e How to choose the right value for TBPRD )

Regards,

Osama

Hi Osama,

Did you go thorugh this doc: http://www.ti.com/general/docs/lit/getliterature.tsp?literatureNumber=spruge9e&fileType=pdf

The above file would clear all your doubts on PWMs.

Hi Gautam,

Those the documents I went through. I did not find any details about how functions work.

Thank you,

Osama, I really don't know what more do you want than those documents.

I did not find any details about how functions work.

What functions are you talking about?

Hi Gautam,

I will try to go over the documents over again. I thought there are other easier documents to understand.

Sure Sure, those documents and the sample codes in controlSuite are more than enough to implement any project.

Good luck and do revert if you face any further issues.
