Recently, reduced device count multilevel inverter is getting more attention for PV applications due to high efficiency, modularity, simplicity and compactness. Therefore, in this paper, a new single input DC source based two stage transformerless five-level inverter with reduced devices is presented. The front-end boost converter is capable to maintain dc link voltage across the capacitors to obtain the desired output voltage. Whereas the T-type inverter is used to generate the five-level output voltage waveform by comparing a carrier waveform with two modulated sine signals. The proposed topology is tested for different conditions of load changes and modulation index in the MATLAB/Simulink software. Moreover, a comprehensive comparison is made with recently proposed topologies to highlight the merit of the proposed topology. Finally, concluding remarks are presented at the end.
