S. Sivaranjani, Dr.A. Ezhilarasi and Dr.M. Ramaswamy

The concept of a Fuzzy Sliding Mode Controller (FSMC) for regulating the output voltage and the Total Harmonic Distortion (THD) across the operating range for solar boost inverters is reported in this technical article. The philosophy of the inverter relates to extracting an ac output at desired amplitude and frequency from the available solar power input. The Boost inverter for the SEPIC MPPT scheme shows a high precision in current transition and keeps the voltage without any changes. The theory of the proposed strategy is not only regulate the output voltage but also guarantees better quality of power transfer to load and near-perfect tracking accuracy (dynamic reaction, over-shooting, steady-state error), In addition to providing greater robustness and reliability. The MATLAB based simulation fosters to bring out the merits of FSMC over the conventional Fuzzy Proportional Integral (FPI) controller in terms of lower THD and Harmonic Spilt Factor (HSF) for the output voltage. Both the hardware implementation and the simulation performance were evaluated and exhibit its ability to suit real world system
