A novel SVC algorithm for multilevel Z-source inverter

This paper proposes a new strategy for multilevel Z-source inverter; which employs space vector control (SVC) as control algorithm of cascaded H-bridge multilevel Z-source inverter. In this algorithm different states to generate the same voltage with low THD, as purpose, are verified and the suitable one is selected. This method is simple and has appropriate performance with low THD, where sample time is quite large. Use of Z-network allows the inverter to generate a wide range of output voltage with high reliability. The accuracy of suggested algorithm is validated with simulation results using MATLAB/SIMULINK software.
