N2 - This study introduces a novel high-gain DC-DC converter by integrating a coupled inductor (CI) and a voltage multiplier cell (VMC) into the conventional SEPIC topology. An auxiliary switch, benefiting from zero voltage switching (ZVS), is applied to provide ZVS for the main switch over a wide output power range. Moreover, the employed diodes turn off under zero current switching (ZCS), thus eliminating reverse recovery losses and increasing efficiency. This study conducts a comprehensive analysis and compares the proposed converter with state-of-the-art topologies. The claimed features are verified by implementing a prototype that converts 36 to 250V.
