Lcr Filter; Combination Of L, C, And R - Hitachi SJ300 Series Manual

LCR Filter

The LCR filter smoothes inverter output current and voltage waveforms and reduces vibrations in the motor, noise
from the motor, and radiated noise from the wires.
The LCR filter suppresses a voltage surge that occurs at the motor terminals when driving a 400V class motor.
