“…The 3-level SEPIC topology is shown in Figure 4, which employed as a DC to DC converter with the enhanced voltage level at the DC-link. The main role of SEPIC unit is to trnsform DC to DC with better conversion ratio [20][21][22]. For the boost operation of the converter, it has to be functioned at a duty cycle above 0.5.…”

“…Due to low efficiency, low power density and high voltage stress across the switches [17][18][19], this kind of converters are replaced by the 3level converters with high power density and reduced switching losses. The 3-level converters are widely [20][21][22] used in the solar PV systems for DC/DC conversion with enhanced voltage levels, low ripple current and minimized losses. In this paper RBFN controller based three level SEPIC configuration is designed for 1.2kW solar PV system.…”

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.

“…Conventional boost and the buck-boost converters [34,[37][38][39][40][41][42][43][44][45][46]. For various applications Ćuk, SEPIC and Zeta topologies are preferred over conventional buck-boost converter for their better efficiency and continuous input current [47][48][49][50][51][52], albeit having higher component count [53]. Some attempts to create hybrid converters by crossover structures including the boost and the Ćuk topologies, but at expense of the extra components devoid of enhancing voltage gain characteristics [28,50].…”

In this paper, a comparative analysis has been presented on various topologies of isolated and non-isolated DC-DC converters. Here, the major focus remains on transformer-less (TL) DC-DC converters, based on the conventional basic boost converter. In addition, to attain high voltage gain, a classification of non-isolated converters based on extendable and non-extendable design has been presented. For comparative and theoretical analysis, the parameters chosen are the number of components utilized by each converter topology, high voltage gain offered, voltage stresses on each component involved and the efficiency of the high gain topologies. For the converters under discussion, operation under ideal and non-ideal conditions has also been highlighted. Based on this study, authors present a guide for the reader to identify various high voltage gain topologies for photovoltaic (PV) systems.
