A switched-inductor switched-capacitor based ultra-gain boost converter: analysis and design

Resumen en inglés

A feature known as high-voltage gain conversion is necessary for a number of applications, including photovoltaic (PV) connected systems, UPS, SMPS, and some inverter applications, specifically for the power processing of low-voltage renewable sources. This article makes a suggestion for an ultra-gain boost converter based on a switched-inductor switched-capacitor (SISC) network. Ultra-voltage gain (> 15) and lower voltage stresses across the switches are the main benefits of the proposed converter. Additionally, compared with other high-gain topologies, the number of components decreases. This paper presents a systematic analysis of the proposed ultra-gain boost DC–DC converter along with a comparison to other topologies that have been previously published in the literature. The simulation model confirmed that the efficiency of the proposed topology is 95.23%.
