3 phase Pure sine wave inverter

I want to design three phase sine wave inverter using Arduino I have already implement single phase sine wave inverter using pic microcontroller available on this link http://microcontrollerslab.com/pure-sine-wave-inverter-using-pic-microcontroller/ Mr Malik has done very good work. But now I want to design three phase inverter.

Can any body help me out how can I generate phase shift of 120$ between three SPWMS as post on the link given.

Kindly reply I will be very thankful to you

thanks :slight_smile:

there are likely many ways to generate 3 sine waves 120 deg phase apart..
u might start here--
with the playground example for generating one sine wave

and then it should be pretty simple to just sample from the table 1/3 ahead and 2/3 ahead
for the other two legs..

I finally designed three phase sine wave inverter using Arduino you can check this link for more information on circuit and code

Nice. What do you use it for?
