Asymmetrical Multilevel Inverter-Based PV System with Voltage Feedback Control: An Experimental Validation

This paper presents an experimental evaluation and validation of a standalone photovoltaic (PV) renewable energy system using perturb observe MPPT-based voltage controller (POVC) for application on the reduced component multilevel inverter (MLI). The objective is to verify effectiveness POVC asymmetrical MLI real PV interconnection applications, which has never been reported before. An 17-level topology selected in this research. It requires four isolated DC sources operate. A boost converter deployed as one inputs while power supplies others. implemented at control from panel. From results, capability produce constant levels under varying conditions proven. also capable delivering maximum load. full tested different load types, including nonlinear loads. produces expected outputs all operating with efficiencies above 97%. viability proposed firstly analysed through MATLAB/Simulink simulations. results are then evaluated experimentally.
