Improved space vector modulation algorithm of 5-level three-phase z-source based cascaded inverter

The integration of a Z-source network with 5-Level three-phase inverter based cascaded to provide voltage step-up function is proposed in this paper. system controlling by an improved space vector modulation (SVM) the implantation algorithm and innovative virtual automated solutions can be considered, very fast simple. main objective achieve output twice applied input voltage, eliminate largest amount excess harmonic. This model characterized ease boosting depending on characteristics without need for DC-DC rectifier. Furthermore, improving eliminating large number harmonics while greatly simplifying calculations compared its conventional SVM. makes interesting alternative classical systems algorithms. simulation was processed using MATLAB/Simulink. results obtained prove verify effectiveness system. From results, current total harmonic distortion (THD), it reduced 1.05% which low other algorithms literature.
