B.4.3 Applications for AC Reactor
Connected in input circuit
Application 1
Question
When more than one AC motor drive is
connected to the same power, one of them is
ON during operation.
When applying to one of the AC motor drive,
the charge current of capacity may cause
voltage ripple. The AC motor drive may
damage when over current occurs during
operation.

Question
Silicon rectifier and AC motor drive is
connected to the same power.
Surges will be generated at the instant of
silicon rectifier switching on/off. These surges
may damage the mains circuit.
