Hello guys,
Is anyone aware of an IC or module which requires only sine wave as input and generates spwm according to that sine wave. I am actually working on grid connected inverters. Any help will be appreciated. Also can you guys recommend any feedback technique for accurate voltage synchronization.

Thanks in advance
 

Hi,

Sinwave to SPWM:
It's basically just a triangle (or sawtooth) signal compared with the sine input.
Thus an OPAMP and a comparator does the job.

I don't know a ready to buy IC.
