Abstract (en)
[origin: WO03007318A2] The invention relates to a swinging choke with a symmetrical double E core. Said choke has two geometrically identical coil windows, a rectangular parallelepiped center branch (17) and two rectangular parallelepiped outer branches (18, 19). The double E core has a cross-sectional surface of the center branch (17) that is greater than 90 mm<2>, the longitudinal cut being considered as the cut that would part the double E core in two simple E cores, and the cross-section is perpendicular relative to the longitudinal cut in such a manner that the double E can be recognized in the cross-section. The double E core is disposed in a component volume smaller 26.5 mm x 26.5 mm x 15 mm (breadth x depth x height).
