Blocking filter for appliances with carrier frequency utilisation in low-tension networks

摘要

Band-stop filter for equipment with carrier-frequency utilization of low-voltage lines, including a current-compensated choke having a closed ferrite core, two center taps, and two coil halves each of which having windings being connected to one of the center taps and wound with the same sense on the closed ferrite core, and a capacitor connected between the center taps.
