3 Phase inverter in this demonstration, uses space vector modulated PWM to generate the output voltage.
Reference voltage vector converted in to dq rotating phase. A matlab function is employed to determine the segment number and related ON-times(ti,t2,t0/2).
Symmetrical switching method employed to minimize switching losses.

SVM trajectory will be plotted at the completion of the simulation.
