Electromagnetic filter module has a three phase electrical coil and capacitor circuits with a central frame having electrically isolating plastic foils

摘要

The electromagnetic filter module has a three phase current compensated coil on a magnetic core. The electrical circuit is mounted on two circuit boards [3,4] and is based upon capacitors [30,40]. The unit has a central frame [1] in the form of a metal pressing and contact with the coil windings is prevented by plastic foils [51,52].
