7-4 Line & Load AC Reactors (Chokes)
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.
