power factor correction Last modified: Friday, September 26, 2008
Power factor correction (PFC) is a newer technology used in computer power supplies. PFC is applied to the circuits that include induction motors as a means of reducing the inductive component of the current and thereby reduce the losses in the supply. PFC has no effect on the operation of the motor itself. [Source: Adapted from LM Photonics Ltd]

Advantages Using A Boost-Follower In a PFC Pre-Regulator (PDF) Conventionally, PFC (power-factor corrected) off-line power converters are designed with two power stages: The first stage is typically a boost converter because that topology has continuous input current that can be shaped through the use of a multiplier, and average current mode control, to achieve near-unity power factor (PF.) However, the boost converter requires a higher output voltage than the input and requires a second converter to step this voltage down to a usable level.
