        abstract = {The rapid expansion of electric vehicles, renewable energy systems, and multi-voltage portable electronics has intensified the demand for compact, efficient, and cost-effective power distribution architectures. Single-Input Multiple-Output (SIMO) DC-DC converters offer a practical solution for deriving multiple regulated voltage levels from a single source; however, conventional topologies frequently suffer from high switch counts, complex control schemes, unbalanced thermal stress, and increased manufacturing costs. To address these limitations, this paper presents a novel single-input three-output DC-DC buck converter topology. Compared to traditional SIMO designs, the proposed architecture eliminates two switching devices, significantly reducing system cost, simplifying gate-drive requirements, and promoting a more balanced distribution of power losses across the active switches. A comprehensive analytical framework is developed, encompassing steady-state operation, detailed small-signal modeling, and optimized multi-output control strategies with PWM implementation. The static and dynamic performance of the converter is rigorously evaluated through MATLAB/Simulink simulations, demonstrating stable voltage regulation, fast transient response, and high operational efficiency under varying load conditions. These simulation outcomes are corroborated by experimental prototype testing, validating the accuracy of the theoretical models and the practical feasibility of the design. The results confirm that the proposed SIMO buck converter is highly suitable for electric vehicle battery management, renewable energy integration, and multi-rail power systems. By delivering a structurally simplified, cost-efficient, and thermally balanced alternative to existing topologies, this work provides a scalable foundation for next-generation power electronic applications.},
