摘　　要：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 P_(max)(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.
