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.). The 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 the mains power capacity is too large,

line impedance will be small and the charge

current will be too high. This may damage AC

motor drive due to higher rectifier

temperature.
