Power Factor Correction (PFC) - Mixed Media

Power factor correction (PFC)

Standards and requirements are growing for increased efficiency in all power systems. Systems that have a low, or uncorrected, power factor (PF) will impact on losses in the local power conversion system and electrical distribution system. Therefore circuit designers will need to utilise power factor correction to meet distribution requirements. Bourns offers a wide range of power inductors and snubber and current-sense resistors, including wire-wound, thick-film, metal-strip and metal element types, to help engineers meet PFC application requirements.
