Abstract: A power supply system comprises an AC input, an AC output, and a DC input; a DC intermediate circuit; a first converter connected, via a first bistable switching circuit, between the AC input and the DC intermediate circuit; a second converter connected, via a second bistable switching circuit, between the DC intermediate circuit and the AC output; a third converter connected, via a third bistable switching circuit, between the DC input and the DC intermediate circuit; a bypass circuit connected, via a bypass bistable switching circuit, between the AC input and the AC output and configured to provide a bypassing path from the AC input to the AC output; and a control unit.

Abstract: 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.
