The Capacitor Bank Automatic Controller is a Power Electronics project that combines Voltage and current sensing and Harmonic analysis, built with Arduino. The project follows a clean, modular pipeline where power conversion, control, and monitoring stay separated, making it easy to test, extend, and present. It showcases practical Power Electronics techniques while producing a working, demo-ready system.
Conventional power systems for this task are inefficient, costly, and lack precise control. Without a Power Electronics approach built on Harmonic analysis and Arduino, users cannot efficiently convert, regulate, and control electrical power, and there is no reliable way to monitor or improve performance.
This project applies Power Electronics techniques through Voltage and current sensing, orchestrated with Arduino and Harmonic analysis. The system is designed for efficiency and safety, with power stage design, control logic, and clear evaluation. It produces consistent, reusable results and can be adapted to related power tasks with minimal changes.
