  "account": "A novel DC-DC converter has been designed, combining a single switch with a high gain and minimal components, specifically tailored for renewable energy applications. This innovative topology leverages a Three-Winding Built-In Transformer (TWBIT) in conjunction with a voltage multiplier to achieve an impressive voltage conversion ratio, all without the need for a large duty cycle. By adopting a real trans-inverse configuration, the converter significantly enhances voltage gain while simultaneously reducing switch voltage stress, a feat unattainable with traditional coupled-inductor designs. The incorporation of a regenerative clamp capacitor further minimizes the switch's voltage stress, offering exceptional design flexibility through adjustable turns ratios. This configuration boasts three major benefits: reduced voltage stress on the power switch, utilization of the TWBIT's leakage inductances to facilitate soft-switching and mitigate diode reverse-recovery, and the creation of a resonant cell from these inductances to diminish switching dissipation. These elements collectively contribute to heightened conversion efficiency. The theoretical operation and steady-state performance are meticulously analyzed, followed by experimental validation of a 200 W, 25 V-to-400 V prototype, which confirms the converter's superior performance metrics. This research, conducted by the Department of Electrical Engineering at Ram.C., Islamic Azad University, Ramsar, Iran, and published in *Scientific Reports* under a Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International License, underscores the converter's potential in enhancing renewable energy system efficiency.",
