FN 6840

LCL Filter for Active Front End Motor Drives / Active Infeed Converter

  • Line side LCL filtering for AFE/AIC applications
  • Mandatory interface to connect the AFE/AIC-system to the grid
  • Helps to improve the power quality on the grid side
  • Reduces ripple currents and voltage distortions
  • All LCL components in one package
  • Compact design and ready to be connected

Features and Benefits

Improves the power quality for AFE (Active Front End) / AIC (Active Infeed Converter)
Effective attenuation of converter switching frequency to the grid/line side
Reduces the current and voltage ripples to acceptable levels for the grid/line side
Version with passive RLC damping module for system stability
Compact and user friendly design for ease of installation

Typical applications

Hoists and cranes
Elevators
Test stands
Winder/Unwinder
Multiple motor drive systems with AFE/AIC
Motor drives and -systems with braking energy
Special machines with high inertia
Centrifuges
Transportation systems, e.g. chair lifts etc
