The efficient conversion of solar energy into electrical energy is a fundamental aspect of photovoltaic (PV) systems, and the choice of DC-DC converter serving as intermediate stage plays a crucial role in optimizing performance, efficiency, and reliability. This paper provides an in-depth examination of various DC-DC converter topologies used in solar PV applications, including buck, boost, buck-boost, Cuk, Zeta, SEPIC, and flyback converters. Each converter is analyzed in terms of its operational principles, advantages, limitations, and suitability for different PV system configurations. The paper also explores the impact of these converters on power conversion efficiency, voltage regulation, current ripple minimization, and system stability, addressing the challenges posed by fluctuating environmental conditions. By comparing and contrasting these converter topologies, this review offers valuable insights for researchers, engineers, and industry professionals seeking to optimize solar PV systems for higher efficiency and better integration with the grid. The findings highlight the importance of selecting the appropriate DC-DC converter to enhance the overall performance and reliability of renewable energy systems, contributing to the continued advancement of sustainable power generation exciter open-phase faults, respectively, are detectable with at least a 95% confidence interval.
