Revision May 2009, BWE0, SW V1.05
Application 3
Question
Used to improve the input power factor, to
reduce harmonics and provide protection from
AC line disturbances (surges, switching spikes,
short interruptions, etc.). AC line reactor should
be installed when the power supply capacity is
500kVA or more and exceeds 6 times the
inverter capacity, or the mains wiring distance
≤
10m.
When power capacity is too large, line
impedance will be small and the charge
current will be too large. That may damage
AC motor drive due to higher rectifier
temperature.
Correct wiring
large-capacity
