Definition

Methods and circuits, either passive (capacitor banks, inductors) or active (power electronic converters), applied to AC power supplies to reduce the reactive component of current and bring the mains input current waveform closer in phase and shape to the fundamental voltage, thereby reducing apparent power and improving supply utilization.
