This paper presents three-level Modular Multilevel Half Bridge Inverter to achieve lower total harmonic distortion and improved efficiency. Compared to conventional inverter, multilevel inverters provide output voltage of high quality and current waveform while using the low switching frequency. The use of multilevel inverters reduces the switching losses, size of semiconductor switches and the number of harmonic filters as compared to the traditional DC-AC inverters. This paper investigates different classification of multilevel inverters suitable for photovoltaic applications of high power based on efficiency and THD of the output line voltage and current waveform. Multilevel Inverter topologies are simulated as the same environment using MATLAB/Simulink.
