INFORMATION

Description

LCL filters have been specially designed to eliminate the harmonics from the current absorbed by 6-pulse power converters, such as frequency variators for motors, UPS, etc. These are essentially passive filters based on a series-parallel combination of inductances and capacitors, adapted to filter the input of power converters.

Applications

  • Reduction of the current wave's distortion towards the network and the rest of the installation.
  • Compliance with the IEC 61000-3-4, IEC 61000-3-12, IEC 61800-3 and IEEE-519.
  • Energy savings with the reduction of the root mean square current (RMS), thus reducing the kV·A demand.
  • Increase of the working life of units above this location with the corresponding reduction of thermal losses generated.
  • Limits current transients, preventing damages caused to the converter and overvoltage trips that affect production processes.
