Abstract
In a system for the elimination of radio noise, both balanced-to-ground as well as unbalanced-to-ground noise currents are employed. Attenuation is achieved by employing current-compensated noise elimination chokes whose leakage inductance is increased by a magnetic shunt. In order to simply manufacture a magnetic shunt which can be distributed well over the windings, the choke is provided in a container filled with a casting compound, and a powder consisting of a material with good magnetic conductivity is embedded in the casting compound in the proximity of the choke.
