About Power Factor Correction (PFC) Products
Power factor correction (PFC) products are used to configure and correct the power factor in power systems. The power factor describes the power relationships on an ac power line. Current and voltage distortions occur with a reactive load, which has both a real and a reactive power component. The vector sum of these two power components is the apparent power to the load. The phase angle between the real power and the reactive power is the power factor angle. With a resistive load, the reactive power is zero and the apparent power equals the real power. The power factor is unity, or 100%. If the load is reactive, the power factor is lower (less than 100%). Understanding these power-factor characteristics is an important part of specifying power factor correction (PFC) products.
