The bad effect of zero sequence current in unbalanced load when connected to three-leg inverter is the main challenge leading to add fourth leg and using three dimensional space vector pulse width modulation (3-D) SVPWM technique to handle this problem. The paper presents an analysis and study of this technique, depending on the average large signal model. This technique simulated by using Matlab/Simulink and the results shows good performance with low THD for different operating conditions.
