TMS320F28034: Sine of ramp output can not generate pure sine wave?

Shaoxing, can you provide me a bit more context here? Where is this code from? C2000Ware or ControlSUITE? Which library?

Hi Sira, 

ControlSUITE.

C:\ti\controlSUITE\libs\app_libs\solar\v1.2

Please help to find the reason why  we use the RAMPGEN_IQ can not generate pure sine wave?

Shaoxing,

This particular lib is not familiar to me. Nowadays we support reference generation in the DCL in C2000Ware.

Thanks,

Sira

Hi Sira,

Could you loop the right person who cover the particular lib here? Thanks.

I am not familiar with this either. I will ask  reassign this question

Please see the code for this design where we used the rampgen and the PLL to generate ref sinewave. This is the Solar Micro Inverter design. You can find the code for this design in ControlSuite. 

Below is a snapshot of a page from the User Guide of the Solar Micro Inverter showing how these s/w modules are connected
