| Summary: | This paper proposes two advanced algorithms for multilevel Z-source inverter (MLZSI), which employ space vector control (SVC) as control algorithm of cascaded H-bridge multilevel Z-source inverter; where output voltage is achieved by summing the output voltages of bridge. In these algorithms different states to generate the same voltage with low THD, as the purpose, are verified and the suitable one is selected. This method is simple and has appropriate performance, where sample time is set quietly. Use of Z-network allows the inverter to generate a wide range of output voltage with high reliability. The accuracy of suggested algorithms is validated with simulation results using MATLAB/SIMULINK software and experimental results based PCI-1716 data acquisition system.
