Tool/software: Code Composer Studio

Hello,

I Gaurav Sharma, is a master student .I am working on control card TMS320F28335.I am a tyro person in this field.I am working on single phase solar inverter and i need to generate gate pulses for switches by using above micro controller. I need sine pwm gate pulses. I do not have knowledge in C programming. Can somebody help me in this case. Can somebody provide me code for sine pwm (sinusoidal pulse width modulation).

Hi Gaurav,

You have libraries for generating SPWM. You can refer the Signal Generation library by downloading controlSuite and navigating to:
C:\ti\controlSUITE\libs\dsp\SGEN\v101

Thank you so much sir,

I have gone through that link and examples file (C:\ti\controlSUITE\libs\dsp\SGEN\v101). To get SPWM, I need to generate triangular and sine wave and comparison of both will give me SPWM. Will those example files and signal generation do this ?

The above would have the Sine lookup table and linear interpolation. Please do go through the manual available in the same folder.
Alternately, you can have a look at this implementation:
