How can I generate simulink model of Sinusoidal PWM for TI launchpad c2000

I have generated ePWM using block given in library. but I am unable to generate SPWM and also facing the problem to have phase shift in generated PWM.

Hi Swapnil,

1. What are the settings you have made in the ePWM block?

2. How are you providing the input to the ePWM block?

3. What output are you observing at the output of ePWM block?

Did you find a solution to this?

Hello,

In ePWM module go to ePWMA or ePWMB tab and set "Specify CMPx via" on "Input port", then connect

the Wx input port to a sine wave block.

In sine wave block set "sine type" on "sample based".

Could you share a detailed account of the solution？I tried your method, but it didn't work. The pulse width of PWM signal generated was still the same.

I have used launchpad F28027 with simulink to generate code from direct simulink model. But when I tried to generate the code from one of my model which I need mainly I am facing error. I dont know what is the problem exactly. I want to generate 10KHz switching signals for my Z-source inverter......

Can you help me solving the problem.
