Implementation of Space Vector Modulation (SVM ) Inveter

Prelude
SVM is a sophisticated digital control algorithm employed in modern Inverters for the generation of a three phase pure sine AC voltage. SVM Inverters are mostly used to power high performance industrial drives such as three phase AC induction motors. Unlike the conventional sinusoidal PWM, this form of modulation utilizes more available DC supply voltage (15% more voltage output), produces a sine wave with less Total Harmonic Distortion (THD) and offers more degree of freedom in the implementation [1].
