In space vector pulse width modulation , Maximum Modulation index for linear modulation is .907 or .866?

07 July 2015 0 9K Report

In some paper they are taking maximum modulation index as .866 and In a paper its mentioned like "Linear modulation extends up to Vref = 0.866. The corresponding modulation index (MI) equals 0.907".

Im confused. What is the actual MI equation?

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??
