Question

Used to improve the input power factor, to

When power capacity is too large, line

reduce harmonics and provide protection

impedance will be small and the charge

from AC line disturbances. (surges,

 

current will be too large. That may damage

switching spikes, short interruptions, etc.).

AC motor drive due to higher rectifier

AC line reactor should be installed when the

temperature.

power supply capacity is 500kVA or more

 

and exceeds 6 times the inverter capacity,

 

or the mains wiring distance 10m.
