Power Factor Correction Capacitors: Enhancing Electrical Efficiency Power Factor Correction (PFC) capacitors are essential components in electrical systems, designed to improve power factor by compensating for reactive power caused by inductive loads such as motors and transformers. By introducing a leading current, these capacitors counteract the lagging current drawn by inductive equipment, thereby reducing the phase difference between voltage and current. This correction minimizes energy losses, enhances voltage stability, and optimizes the overall efficiency of the power system.
