High pulse AC/DC convertors and their application to HVDC transmission. [PDF]
, 1992 AC/DC convertors used in HVdc transmission systems inject harmonics into their associated AC and DC systems. A conventional approach to filter these harmonics is to use passive filters on both AC and DC sides of the convertor.
