Ratings of active power filters [PDF]

open access: yesIEE Proceedings - Electric Power Applications, 2003
The fitting of an active power filter (APF) to mitigate the effects of a diode or thyristor bridge-rectifier is predicated on the assumption that the rating of the filter is reasonable (i.e. small) compared with the rating of the existing bridge rectifier or of a replacement active rectifier.
