Power Factor Correction (PFC) Explained | Article | MPS
In order for an AC/DC power supply to be efficient and safe, it needs to incorporate isolation, power factor correction (PFC), and voltage reduction. These elements protect the user, the grid, and any connected devices, and are each integrated to some extent in …
A power factor correction (PFC) circuit is added to a power supply circuit to bring its power factor close to 1.0 or reduce harmonics. This application note discusses the basic topologies of the PFC circuits and their operations.
