Design and Optimization of High-Gain DC-DC Converters with Switched Capacitor for Solar Applications

The growing need for efficient and compact power conversion systems in Photo Voltaic (PV) energy harvesting has driven the investigation into high-gain topologies that can elevate voltage levels. The proposed converter incorporates a Switched Capacitor (SC) mechanism to achieve high conversion efficiency and increased output voltage gain, solving the problem of Solar Panels (SP) low voltage output in an efficient manner. The optimization strategy aims to minimize energy losses, enhance the converter's dynamic performance, and improve its stability under varying load and input conditions. A thorough examination of the converter’s operation is provided, along with simulations and comparisons to conventional DC-DC converters, showcasing superior voltage conversion efficiency and system reliability. This paper outlines the design and optimization of high-gain DC to DC converters with a SC mechanism for solar energy applications, presenting a promising approach to enhancing solar power system performance and contributing to more efficient and sustainable energy use in renewable energy applications.
