Abstract
Power factor correction (PFC) is crucial in improving the efficiency and stability of electrical power systems by reducing reactive power. This manuscript presents a microcontroller-based automatic power factor correction system that dynamically monitors and corrects the power factor by switching capacitor banks. The proposed system utilizes real-time measurements of voltage and current to compute the power factor and accordingly controls the capacitor banks to maintain it near unity. The study includes system design, implementation, simulation, and experimental analysis with statistical evaluation. Results demonstrate improved power factor, reduced losses, and enhanced electrical efficiency, confirming the viability of microcontroller-based automatic PFC in industrial and commercial applications using technologies available up to 2019.
