Comparison of MLI and Z-Source Inverter for Transformerless Operation of Single-Phase Photovoltaic Systems

Year: 2010

Type: article

Abstract: This paper presents a comparative analysis of single-phase transformer-less photovoltaic inverters and the topologies are compared in terms of efficiency, DC current injection and regulation. A model of cascaded multilevel inverter and Z-source inverter is built in MATLAB/SIMULINK and its performance is analyzed. Phase disposition control scheme is used for pulse generation for cascaded multilevel inverter and maximum boost control is used for Z-source inverter. The effects of intensity and modulation index on the output voltage are studied through simulation and prototypes of the inverters are implemented. The simulation, and the experimental results are presented in this paper.
