Abstract
A filter system includes at least two longitudinal branches with longitudinal inductors and at least one filter section (B) and an adjacent filter section (A). The filter section (B) is provided with at least one transverse branch that is interposed between the longitudinal branches, the adjacent filter section (A) adjoining the transverse branch. The number of inductors of a filter section that arc wound around different magnet cores can be reduced by equivalence transformation.
