You want channel 2 to be the exact opposite of channel 1 and don't see how an inverter could be handy?

I suggest you google <electronic tutorial logic gates>.

Multi_SPWM not suitable for Inverter project & I tested this for Inverter and the result was worst. Plz modify this Multi_SPWM software.

hello bro,
I just need help that I post. But you mean something different. I don't want to rent someone knowledge.

What he is trying to say is, when you make a statement like the following:
"Multi_SPWM not suitable for Inverter project & I tested this for Inverter and the result was worst. Plz modify this Multi_SPWM software."
it makes us think you want us to do the project for you. You got the routine for free but you don't understand how it works. Now you want someone to please fix it for you. Don't you know any thing about the language? Don't you understand the processor you are working with. People are here to help but, not to re-write someone elses code to suite you. I see this all the time, someone asking for the forum members to write there code for them.

Just my 2 cents worth.....
