Passive Harmonic Filters
Passive harmonic filters help to obtain compliance with international standards, e.g. IEEE 519 or IEC/EN 61000-3-12, and with local utility codes. They reduce electrical and thermal stress upon the electrical infrastructure, significantly reduce the risk of harmonics-related reliability problems, and support long-term energy efficiency and cost savings. ECOsine passive harmonic filters are the industry standard for 6-pulse rectifiers and non-regenerative motor drives to achieve the often-specified level of THDi <5%.
ECOsine harmonic filters represent an economical solution to the challenge of load-applied harmonics mitigation in three-phase power systems. With a plug-and-play approach and more compact dimensions than comparable products, they can be quickly installed and easily commissioned. They increase the reliability and service life of electric installations, help utilize electric system capacity better, and are the key to meeting power quality standards such as IEEE 519 and relevant IEC/EN 61000 standards. Ecosine filters reshape your distorted current back to the desired sinusoidal waveform. ECOsine filters can be applied to virtually any kind of power electronics with front-end six-pulse rectifiers, 3-phase diode or thyristor bridges, where harmonic current distortion needs to be reduced to defined limits. The three passive harmonic filter (PHF) product families, ECOsine Evo PHF, ECOsine Max PHF and ECOsine Flex passive harmonic filters, [TS1] offer solutions for 3-phase 200V to 480V motor drives at 50Hz or 60Hz, with two performance levels and various options to accommodate the most demanding applications.
