What is the purpose of using 1.2 here in sine pwm. In space vector pwm i saw source voltage divided by 1.8. Why is it used? For what purpose?Please explain with sufficient theory

1.8 might be a crude approximation of sqrt(3), the power adjustment needed to account for the voltages being out of phase (so you get more peak power than you would get from just one phase, but not as much power as 3 times what you get from one phase.)
