In summary, power factor is on the list of concerns for designers of virtually every device that draws significant power from a mains socket, as well as for engineers in heavy-electrical sectors. The power factor target plus efficiency, component cost, and volume/board space all need to be considered. For this reason CUI has designed active power factor correction into the vast majority of its AC/DC power supplies from 100W and over to help ease implementation and ensure international compliance for OEMs. To find out more, view CUI’s portfolio of AC/DC power supplies with power factor correction at DigiKey.
