Abstract

This paper presents the performance analysis of a half-cascaded multilevel inverter topology. The inverter consist of a new nine-level hybrid inverter with less number of switches. A carrier based level shifted PWM (LS-PWM) technique have been used to generate the output waveforms of the proposed multilevel inverter. The modulation index of the multilevel inverter has been controlled to control the output voltage of the inverter. The validation of the model is done in MATLAB/SIMULINK environment. The simulation results of the inverter output voltage, load current and the % total harmonic distortion (THD) of the proposed ninelevel inverter at different modulation index is presented. The comparison of the proposed multilevel configuration with conventional cascaded H-bridge multilevel inverters for same number of voltage levels.
