Application 1

Question

When more than one AC motor drive is

connected to the same mains power, and one

of them is ON during operation.

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.
