Abstract
In presented article, an extendable non-isolated high boost converter based on switched-inductor and capacitor-divided (SLCD) network is designed. The high gain, single switch, continuous input current and common ground structure makes it suitable for solar PV applications. The voltage stress across the semiconductor devices is less than the output voltage thus enhancing the efficiency of the converter. The operation in continuous and discontinuous mode of the converter with precise design parameters is presented. A meticulous analysis of voltage gain and efficiency is presented considering the inbuilt resistances of the components and the small-signal model developed evince the stability of the SLCD converter. The proffered converter is weighed against other recent congruent topologies. The theoretical analysis is supported by an experimental set-up of 150W prototype.
