Power Factor: Improvement & Correction Methods | Electrical4U

Power factor is a dimensionless number in the closed interval of −1 to 1. The "ideal" power factor is one (also referred to as "unity"). This is when there is no reactive power through the circuit, and hence apparent power (kVA) is equal to real power (kW). A load with a power factor of 1 is the most efficient loading of the supply.

How To Calculate Power Factor Correction | Chapter 4

As mentioned above, to achieve power factor correction, the magnitude of the reactive power created by the parallel capacitor must be equal to the reactive power created by the inductance. Our measurements indicated that the current supplied by the source, and hence the current through the inductor, has a peak value of approximately 1.56 A.

PFC is an acronym that stands for "power factor correction". Power Factor is defined as the ratio of real (true) power flowing through the load to the total (apparent) power in a circuit. Real power is the work performing capacity of the circuit at a particular time and apparent power is nothing but the product of voltage and current.
