Summary:This paper suggests a new switching algorithm for multilevel Z-source inverter. The proposed switching algorithm is based on space vector control (SVC), and employs cascaded H-bridge multilevel inverter, which generates a voltage vector with very low harmonic distortion and reduced switching frequency. Use of Z-network in this topology causes more reliability and bucking or boosting capability of output voltage. This algorithm allows the inverter to generate a wide range of output voltage with different THD, where proper state should be selected for determined voltage among different states. The performance of proposed inverter and switching algorithm are validated with simulation results using MATLAB/SIMULINK software.
