generate SPWM with multicarrier for five level inverter

[Jakie Ee]

Hi, anyone can shows me how to write c code to generate SPWM for five level inverter?

the example circuit is in this link:

Hi Jakie
I hope you don't mean that you reach the 5 level SPWM with micro controller only ? clarification : 5Level SPWM is not just an SPWM . methods for creating such a signal are so different .
For example , creating some SPWM signals and then using some switches to sum them with each other ( certainly when they have been amplified ) .
( if you just have one SPWM signal which is with 5 level you won't be able to amplify it . the signal will be created with a high power summing method which is so easy .
What you need is to create some SPWM signals and try to break the message signal .
I hope you have got the idea
Best Wishes
