Three-phase and neutral line filters are a compact solution for the interference suppression on the mains input of cabinets and control units of equipment, ranging from industrial applications like machine tools to sensitive medical installations. These typically involve separate and often
insufficiently filtered frequency inverters and SMPS, causing current imbalance and significant interference problems. As individual elements they may be interference-suppressed already. The conjunction of several switching components in the same cabinet and a non-EMC conscious cabling will rise the demand for an additional EMC filter on the mains input of the whole installation. Many times this is the only way to get the CE mark for the cabinet in accordance with the EMC directive.

The conventional output-choke has a very good storage capacity. It functions like a typical series inductance and smoothes the symmetrical, effective current and the asymmetrical, parasitic current. The voltage rise is limited to less than 500 V/µs. The line to line voltage peaks at the motor terminals are lower than 1000 V. This solution attenuates the cable-conducted disturbance really well, even in the lower frequency range. The electromagnetic radiation from cables is attenuated considerably. Losses and typical motor noise, caused by harmonics, are reduced.
