Abstract

One of the desirable characteristics of inverters in three-phase systems is the ability to feed unbalanced loads with voltage and frequency nominal values. This paper introduces an innovative control method in combination with a three dimensional space vector modulation (3D-SVM) control strategy. It is able to feed grids with unbalanced loads while reducing the switching frequency losses. The results from this study show that the developed control scheme in combination with three-leg four-wire inverters can carry out the grid feeding requirements under extreme unbalanced load conditions efficiently.
