What is the purpose of using 1.2 here in sine pwm in this simulink. In space vector pwm also I saw source voltage divided by 1.8. Why is it used?

Please explain with sufficient theory

In simulink model, in 3 level Neutral clamped Inverter they are taking positive half dc voltage and negative half dc voltage w.r.t neutral?

And giving it to a MUX and again to demux and then subtracting +Vdc/2 and -Vdc/2 and again giving it to a gain of .5. Why these are required? Why that .5 again?

How can I include space vector PWM converter in simulink just by using some gains? I've read that pwm converter can be modeled as a gain with a delay?

Space vector PWM= Kpwm * e^(-sTsw). What is the value i should give for Kpwm for space vector pwm? e^(-sTsw) is for dead time? And for dead time i should use switching frequency as T??
