AC Reactor
When the AC Motor Drive is connected directly to a large-capacity power transformer
(600kVA or above) or when a phase lead capacitor is switched, excess peak currents may
occur in the power input circuit due to the load changes and the converter section may be
damaged. To avoid this, it is recommend to use a serial connected AC input reactor(6%) at
the AC Motor Drive mains input side to reduce the current and improve the input power
efficiency.

Applications for AC Reactor
Connected in input circuit
Application 1
When more than one AC motor drive is connected to the same mains power, and one of
them is ON during operation.
Problem: When applying power to one of the AC motor drive, the charge current of the
capacitors may cause voltage dip. The AC motor drive may be damaged when
over current occurs during operation.
