Study and control of the Z-source inverter

Abstract

This dissertation presents a study about the z-source inverter. It contains the study of the different control strategies used for the control of the z-source inverter. The control strategies studied in this work are as follow: Simple boost control SBC, Maximum boost control MBC and Maximum constant boost MCBC. A simulation using MATLAB/Simulink is carried out to verify the control strategies, and to compare between them in terms of current ripple, output voltage, current and their harmonic curves. In addition to the shoot- through state on the Z-source network to achieve optimal efficiency.
