CCS/TMS320F28069: Sine Wave Modulated PWM

Daniel Dsa

Part Number: TMS320F28069
Other Parts Discussed in Thread: CONTROLSUITE, C2000WARE

Tool/software: Code Composer Studio

I would like to know how to generate three phase sine pwm. I have sensed three phase grid signals using ADC, and would like to know how to proceed further. Any code that does the same would be helpful.

Hi DAN,

There are multiple inverter examples in controlSuite under:
C:\ti\controlSUITE\development_kits

You can have a look at the documentation of the dev kit your application closely resembles.

Regards,
Gautam

There is a basic three phase sine wave generator in the signal generator library in C2000Ware. If you have that installed in the default location, you can find the documentation at:

C:\ti\c2000\C2000Ware_1_00_04_00\libraries\dsp\SGEN\c28\docs

Beyond that, it very much depends what you are trying to do. There is a 3-phase Vienna rectifier reference design which may be of interest, here:
