Optimal space vector modulation control for three-phase inverter

Abstract

This paper proposes a method for optimization of the harmonic performance of three-Phase inverter under Space Vector Modulation(SVM) control. It is shown that SVM provides a number of degrees of freedom, which make it suitable for optimization, subject to desired constraints. An immune algorithm (IA) optimizer is used to solve the optimization problem. Simulation results are shown to result in significant reduction of dominant harmonics compared with the traditional control strategies. © 2011 Springer-Verlag Berlin Heidelberg.
