Features:
● Use DSP+CPLD all digital control core, three-level topology technology,
advanced harmonic detection algorithm and PWM control strategy to achieve
accurate compensation of harmonic current.
● Adopt modular design, which facilitates parallel connection of multiple
modules, takes up little space and is easy to maintain.
● The structural design of independent air ducts and independent warehouses
ensures the stable operation of the equipment.
● It can filter harmonics in a wide range of harmonics, from 2 to 50
harmonics, and solve the problem of three-phase unbalance at the same time.
● The harmonic filtering rate is high. If the capacity allows, the harmonic
current filtering rate can be as high as 95%. Set 100% current limiting
output to ensure long-term stable operation of the equipment.
Applications:
Three-Phase Four-Wire Cabinet-Type Active Harmonic Filters find application in various sectors requiring enhanced power quality:
