Analysis of a Four-Leg Inverter Feeding a Nonlinear Load using SVPWM Technique

The Three-Phase four-Leg Voltage Source Inverter (3P4L-VSI) has an important role, especially with renewable energy, as an intermediate power electronic as unit stake, that's responsible for producing balance three phase voltage with neutral point, makes it able to handle unbalance and nonlinearity in load. The simulation of proposal system by using Matlab/Simulink and the results shows acceptable performance with low total harmonic distortion.
