3.4.2 Reactor
In order to prevent high grid power to the input power circuit of inverter and damage the
rectifier components, need to install AC reactor in input side of inverter, and it can also improve the
input power factor
When the motor cable is over 80 meters, because of the higher leakage current due to the
capacitance effect of long cable to the grounding, inverter will occur over current protection frequently,
meanwhile to avoid motor insulation damage, need to install output reactor for the compensation.
DC reactor can improve power factor, avoid rectifier damage caused by higher input current, and
avoid the rectifier circuit damage by the harmonic due to the grid power surge or phase controlled
load.

3.4.3 Filter
Input filter: Can reduce the wire interference caused from the inverter to other peripheral
equipments.
Output filter: Can reduce the radio noise and leakage current caused by the motor cable.
