A New Multilevel Renewable Energy System Neuro-Fuzzy Controller
Development and use of single phase-type multilevel inverters have grown more in the last several years. A new topology-based seven-level inverter that uses less power electronics and links to the utility grid is proposed in this research. This proposed multilevel inverter works at basic frequency with only eight power electronics switches. We consider this inverter to be a photovoltaic system because it creates seven modes of output from the input. Because only a few circuit switches are required, the overall cost, complexity and losses from switching are very little. The inverter is responsible for changing the signal from negative to positive, giving us both positive and negative cycles and the DC/DC converter takes that signal and changes it into three positive voltages. Enhancing the output waveform is possible by adding a filter circuit to the output main of the multilevel inverter. To address this, a neuro-fuzzy controller strategy for the seven-level inverter was introduced in this paper. The simulation results are shown in the MATLAB Simulink toolbox.
