Zusammenfassung:	An uninterruptible power supply system includes: at least one AC input terminal; an AC output terminal; an DC input terminal; at least one uninterruptible power supply (UPS) device having: a DC link; a DC/AC converter connecting on a first side to the DC link and on a second side to the AC output terminal; and a DC/DC converter connecting on a first side to the DC input terminal and on second side to the DC link. The uninterruptible power supply system further includes at least two switches; and at least one coupled differential mode inductor having two windings. Each switch of the at least two switches is connected in series with at least one winding of the at least one coupled differential mode inductor forming a series connection. The series connection is connected on a first side to the at least one AC input terminal.
