Passive Filter Outperforms Active Filters In Efficiency

March 3, 2014
MIRUS International has launched its new, high performance LINEATOR Advanced Universal Harmonic Filter (AUHF) that matches the performance of Active Front Ends (AFE) or Active Harmonic Filters (AHF).

MIRUS International has launched its high performance LINEATOR Advanced Universal Harmonic Filter (AUHF) that matches the performance of Active Front Ends (AFE) or Active Harmonic Filters (AHF). Known as the LINEATOR High Performance (HP), it creates efficiency gains of at least 2 per cent and is free of high frequency harmonics and noise issues associated with inverters used in active solutions.

Unlike AFEs or AHFs, the LINEATOR HP passive harmonic filter does not inject higher frequency voltage distortion (frequencies above the 50th up to the 100th harmonic) or higher electromagnetic interference (EMI) common-mode voltages and ground currents into the electrical supply system. These higher voltage harmonics are known contributors to failures in other connected equipment, including power supplies of critical electronic controls, online test equipment, computers, PLCs, circuit breakers with electronic trips and other crucial power system protection equipment.

Specifying the LINEATOR HP for application with standard 6-Pulse VFD's provides end-users with low harmonic drive systems at 20 to 30 per cent less in capital costs than other solutions. Operating costs are also significantly lowered due to the higher efficiency gains.
