Abstract: The integration of high-gain DC-DC converters into photovoltaic (PV) systems plays a crucial role in enhancing energy conversion efficiency and ensuring stable grid interfacing. Photovoltaic panels inherently produce low-voltage DC output, which requires significant voltage boosting to meet the requirements of grid-tied inverters or energy storage systems. This paper presents a comprehensive review of high-gain DC-DC converter topologies, design principles, and their applications in photovoltaic power generation. Key design challenges such as voltage stress, efficiency optimization, electromagnetic interference (EMI), and thermal management are discussed in detail. Advanced control strategies, including pulse-width modulation (PWM), maximum power point tracking (MPPT), and dynamic stability analysis, are analyzed to ensure reliable and efficient operation under varying environmental conditions. The paper also highlights the advantages of soft-switching techniques and multistage converter architectures in achieving high voltage gains with reduced losses. Overall, the integration of optimized high-gain converters significantly improves photovoltaic system performance, promoting wider adoption of solar energy technologies.
