3D SVM for Three Phase Four Leg Inverters using ghY Coordinate System to Reduce Computational Complexity

Three dimensional space vector modulation technique (3DSVM) for three phase four leg inverters with ghϒ coordinate system is discussed in this paper. 3DSVM is the improved version to deal with unbalanced load in three phase inverters. To deal unbalanced load condition in three phase inverters, different modulation techniques like αβϒ and abc coordinate system are used. ghϒ is the new system that combines the positive aspects of previous versions.
