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.
