Advanced cascaded multilevel inverter for PV cell renewable energy system employing incremental conductance MPPT algorithm

The research on multilevel inverter in these days goes on rapidly due to its efficient operation, for various applications. The project proposes an advanced cascaded multilevel inverter which varies from the conventional one from the number of input dc sources used. The proposed nine level multilevel inverter configurations utilize a single dc source i.e., photo voltaic panel, whereas in the conventional multilevel inverter it varies based on the number of levels. The single phase transformer is replaced by the three phase linear transformer to reduce the transformer number. The circuit simulation is made using MATLAB/Simulink software and the performance analysis is made based on THD.
