Experimentation of Boost Chopper Interfaced Cascaded Multilevel Inverter Topology for Photovoltaic Applications

This paper presents the experimentation of Cascaded Multilevel Inverter (CMLI) for Photo Voltaic (PV) generator feeding an isolated load. For the improvement of PV system utilization, boost chopper interfaced CMLI configuration is developed under Multicarrier Sinusoidal Pulse Width Modulation (MCSPWM) control schemes. Boost chopper interfaced CMLI configuration boost up the PV panel voltage and generates high quality of AC power for domestic and drive load applications. The entire systems of PV, boost chopper and CMLI are simulated using SIMULINK and the results are validated. Prototype hardware model of single phase boost chopper interfaced 7-Level CMLI configuration is developed and its output illustrations are validated
