Power Integrations highlights importance of power factor correction at APEC 2017 | EDN


Power factor correction is the process of improving a low power factor in a facility by increasing the ratio of real (working) power to apparent (total) power.

Power-factor correction allows the input current to continuously flow, reduces the peak input current, and reduces the energy loss in the power supply, thus improving its operation efficiency. Power-factor-corrected (PFC) power supplies have a power factor near unity (~1), and thus are highly efficient. The use of energy-efficient PFC devices, including uninterruptible power supplies (UPSs), can lead to significant cost savings.
