become a major issue. e recommended types of compensating lters for this type of harmonic source
are series passive, active, and hybrid lters (a combination of passive and active lters) [41–57].
A current-source type of nonlinear load may consist of a diode or thyristor rectier with sucient
inductance on the dc side such that it produces a constant direct current. It is used in applications such
as dc drives, battery chargers, etc. e current at the input of the rectier contains a large amount of
harmonics due to the switching operation of the rectier. It is recommended in [1] that for optimum ...
