PFC is the acronym for power factor correction or power factor controller. It minimizes the amount of reactive power produced by computers. Reactive power is the power stored and released by the capacitors and inductors of a device. While reactive power is useless to an electronic device, power.
The Power Factor of a power supply is technically the ratio of the real power consumed to the apparent power (Voltsrms x Ampsrms) . Power factor correction is a technique of increasing the power factor of a power supply.

PFC ) can draw approximately 950. A simple load like a toaster . Computers containing PFC (Power Factor Corrected) power supplies and their use Back-UPS and Smart-UPS SC with Step Approximated Sine waves. Active Power Factor Correction also markedly diminishes total harmonics, automatically corrects for AC input voltage, and is capable of a full range of input voltage.
Waveform distortion and the overheating of transformers and neutral conductors in three-phase systems are just a few of the effects.
Equipped with a variety of functions for improving efficiency, driving higher efficiency and eco-friendliness for power supply systems. Driver ICs are also available for high-accuracy, high-efficiency LED lighting systems. If you get a new computer, or a new power supply , it’s possible it might not work with your old UPS.
Active PFC and stepped sine waves do NOT play well together. Active power factor correction can be single-stage or multi-stage. In the case of a switched-mode power supply , a boost converter is inserted between the bridge rectifier and the main input capacitors. Why are active PFC power supplies desirable for military applications?
This is placing higher and higher demands on existing prime AC. Having indicated both of them, the passive and active PFC power supply will be addressed respectiively. FREE DELIVERY possible on eligible purchases.
