You need three sine waves that are 120deg apart in phase.

Let us assume that you have taken one full cycle and taken 100 samples. You store these 100 values for use in PWM. Because of symmetry, you need to store only 1/4 this number.

You start the first wave. When 1/3 of these points are out, you start the second wave from the beginning. When 2/3 of the points are out, you start the third wave. And continue this sequence.

That is all.
