The choke is intended for current supply systems with a chopper for communication apparatus, and has two separate coils for reduction of interference voltages. It has a three-shank core, the two coil being mounted on the outer shanks, while the inner shank has an air gap. Direct current flows through the two coils in such manner that the magnetic flux in the inner shank has the same direction. Preferably the choke has a low inductivity and cooperates with a high value electrolytic capacitors. Two additional capacitors provide the interference voltage reduction. |
