Design of a PV Grid-Tied Zeta Converter with Modified ANFIS Controller

The demand for renewable energy sources (RES) is expanding these days and solar energy are the primary energy sources found in the world. It is a healthy substitute for fossil fuels. As a result, it is now essential to apply power electronics in the solar power producing zone. The main technique for producing such renewable resources fast and efficiently is the use of converters and inverter. In this study, a Zeta converter (shows 94.7 % efficiency) with a modified ANFIS logic controller (shows 95% accuracy) is used to feed photovoltaic (PV) energy sources to load needs. One of the key benefits of the Zeta converter is its ability to maintain consistent input and output currents. It lowers the electromagnetic interference, lower input and output current ripple, and improved dependability. In the event of a changeable load, the modified ANFIS controller for the SEPIC converter, which served as the connection among the power source and the inverter, maintains a constant voltage and displays a little continuous error as well as a minor overflow. MATLAB/Simulink is used to verify the development and evaluation of a Zeta converter based on PVs.
