This study focuses on developing and deploying a closed-loop SEPIC (Single-Ended Primary Inductor Converter) configuration to achieve stable voltage regulation within power electronics. The SEPIC architecture is uniquely capable of producing a consistent output voltage regardless of input fluctuations whether the input is lower or higher than the required level. Through a feedback mechanism, the control loop continuously fine-tunes the switching duty cycle to maintain voltage stability across varying input and load conditions. The design process incorporates careful selection of inductors and capacitors, optimal switching frequency settings, and a responsive digital control system. Performance assessments via simulation and physical prototypes reveal strong results in terms of efficiency, dynamic behavior, and reliability, making the system highly applicable to domains such as renewable energy, portable devices, and automotive electronics.
