0.5 KVA Automatic Stabilizer: Design, Implementation, and Performance Analysis

Electrical Engineering

Voltage fluctuations pose significant challenges to the proper functioning and longevity of electronic and electrical devices. An automatic voltage stabilizer (AVS) is a critical device that maintains a steady output voltage despite variations in input supply. This paper presents a comprehensive study on the design, development, and performance analysis of a 0.5 KVA automatic stabilizer suitable for small-scale domestic and office applications. The stabilizer employs a relay-based feedback control system integrated with a buck-boost transformer to regulate voltage within desired limits. The design considerations include efficiency, response time, stability, and cost-effectiveness. The paper details the circuit architecture, component selection, and control logic, accompanied by simulation results and experimental validation. The performance evaluation demonstrates that the proposed stabilizer effectively maintains output voltage within ±5% of the nominal voltage over a wide input voltage range, ensuring safety and reliability for connected loads. The study concludes with insights into potential improvements and applications, emphasizing its suitability for small-scale electrical systems.
