Abstract
Abstract
This paper analyses the performance of a multiple gain boost converter (MGBC) connected to a solar photovoltaic (SPV) system with a grid-tied inverter. The capacitor inductor capacitor (CLC)-based MGBC is integrated to lift the output voltage of the SPV to the required level. The voltage lifts/levels in a boost converter (BC) are based on the number of CLC cells. The suggested MGBC is compared with various conventional BCs in terms of boost factor and component count. A hybrid fuzzy logic–perturb & observe maximum power point tracker (HFL–P&O MPPT) developed is used to monitor Pmax (maximum power) generated by the SPV. Also, a comparative analysis of the suggested MPPT with a conventional P&O and fuzzy logic-based (FLB) MPPT for a CLC-based MGBC is presented. The comparison is made in terms of rise time, voltage ripples (%), steady-state time and boost factor. The output characteristics of the developed model for different irradiation conditions are analysed using the MATLAB/Simulink tool. The MPPT simulation result exhibits minimum oscillations at MPP and a significantly better rise time of 0.015 s when compared with a conventional MPPT and FLB MPPT. The proposed CLC-MGBC gives an appreciable boost factor of 4. The generated SPV power is supplied to the grid through a conventional inverter and synchronized using a phase-locked loop system. The total harmonic distortion of 1.66% obtained in the output current of the inverter is within the permissible range of the IEEE standards.
