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.
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.
