Abstract: A power supply assembly including a primary source connection, a secondary source connection, a load connection, a primary current supply route, a supply switch system, and a converter system. The supply switch system is electrically located in the primary current supply route, and adapted for disconnecting the primary source connection from the load connection, the supply switch system including a plurality of supply switch units connected in parallel, each of the supply switch units including a controllable semiconductor switch. The power supply assembly includes a series impedance system having at least one series impedance member, and adapted to provide a balancing voltage drop for each of the parallel connected supply switch units of the supply switch system, wherein the balancing voltage drop is in series with a corresponding supply switch 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.
