1. General
The motor using inverter is causing riffle wave form on voltage, and it causes many problems on the
system like breaking down dielectric.
LCF can convert PWM wave form to sine wave form making more safe operation in the system.
2. Problems of Harmonic
•Destroying dielectric in Motor by spike
•Damage on Voltage raising transformer
•Malfuction and reduced life spam of Inverter by inversed voltage.
•Instantaneous Over voltage phenomenon by distorted voltage wave form
•Malfuntion of precision apparatus
3. Application
•Applicable load : Motor and machines using inverter(Between inverter and motor)
•Applicable system: 220V, 380V, 440V, 1000HP
•Applicable place : Plants, Steel Mills, power plant, sewage disposal plants, Garbage dumps etc
〉
•Make smooth voltage and current wave form
•Reduce voltage reflection and surge impedance
〉
•Prevent dielectric destruction
•Increase productivity and quality
•Increase system communication quality and life span
