Power Factor Correction in Household Appliances

Abstract

The increasing use of inductive loads in domestic and industrial settings leads to reduced power system efficiency. This project implements an automatic power factor correction system using an Arduino microcontroller (ATmega328p) to improve power quality. The system measures power factor from single-phase voltage and current signals, calculates compensation requirements, and switches capacitor banks using a 4-channel relay system. This approach enhances power system stability and efficiency while reducing energy losses, making it suitable for household, domestic, and industrial applications.
