<p>The energy demands on the power system are increasing day by day. To meet these growing energy demands, the integration of renewable energy sources (RES) is essential. However, the voltage levels produced by RES are typically low, creating a need for high-gain converters. This paper presents a high-voltage gain converter with a single-switch configuration, specifically designed for photovoltaic (PV) applications. The suggested converter provides multiple benefits, such as a reduced component count, lower cost, simplified gate driver design, enhanced voltage gain, and increased efficiency. The operation of the proposed converter is analyzed in both discontinuous conduction mode (DCM) and continuous conduction mode (CCM), with the corresponding current and voltage waveforms illustrated. The design and efficiency analysis of the converter are thoroughly investigated. Additionally, the converter’s parameters, such as total device count and voltage stress on the switch, are compared with those of existing high-gain converters. The suggested converter is simulated in the MATLAB environment, and its performance is verified through a prototype hardware model with a power rating of 100&#xa0;W.</p>
