Abstract

Highlights• Design of 1.2kW solar PV system with "SUNPOWER-305-WHT" panel. • Radial Basis Function Network algorithm for maximum power point tracking. • A Three-Level SEPIC topology as DC-to-DC converter for enhanced output voltage. • Performance analysis of P & O and RBFN MPPT control algorithms. • Result analysis of a 3-Level SEPIC topology with P & O and RBFN algorithms. Article Info AbstractThis paper accords an intelligent controller based 3-level SEPIC configuration for energy transformation in the solar PV system. An artificial intelligence based radial basis function network is engaged as a control algorithm for the maximum power extraction and the converter control can be done based on the duty cycle generated by the controller. In this system, a SEPIC topology is used for high voltage gain with reduced switching losses. In this paper, an RBFN controller based 3-level SEPIC topology is designed for 1.2kW solar PV system over the traditional P & O (Perturb & Observe) control method and the comparative result analysis is done though the simulation output for the corresponding input parameters.
