Abstract:
1. A high-frequency swinging choke, comprising: at least two rod cores arranged next to one another in a longitudinal direction, each rod core having at least one winding, wherein the at least one winding of each rod core are connected in series and wherein the swinging choke has a closed magnetic circuit with at least one air gap arranged outside the at least one winding, wherein the at least one air gap is divided into at least two partial air gaps near winding-free ends of the at least two rod cores, wherein the at least two rod cores are arranged such that the winding free ends of the at least two rod cores are spaced apart from each other, wherein a magnetic field of the closed magnetic circuit is guided in the at least two rod cores such that the magnetic field exits from a first winding free end of a first rod core of the at least two rod cores in a first partial air gap and enters from the first partial air gap in a second winding free end of a second rod core of the at least two rod cores.
