The sine wave modulation can be optimised by considering:
 |
with the condition to well choose
.
It is sufficient for example to choose P0 so that the reference values are recentered in relation to the reference voltages.
If 
is the biggest of the reference voltages and if 
is the smallest of the reference voltages, we'll recenter the reference values by considering
 |
In this case, the maximum amplitude of the voltages will be 
.
