Abstract: In a power conversion device, cable connection positions of connections in which a plurality of bus bars is respectively connected to external line cables are non-overlapping with each other as viewed from a side on which the external line cables are pulled out.

Abstract: An uninterruptible power supply includes disconnectors that perform a disconnection operation to electrically disconnect a plurality of uninterruptible power supply modules individually. Each of the disconnectors includes a connection conductor that electrically connects a first conductor to a second conductor, and a moving member mechanically moving the connection conductor in a direction in which the connection conductor approaches and contacts the first conductor and the second conductor, and a direction in which the connection conductor is spaced away from the first conductor and the second conductor.

Abstract: In an uninterruptible power supply, first connection members that connect input side-switches of a plurality of uninterruptible power supply modules to each other and that connect output-side switches of the plurality of uninterruptible power supply modules to each other, and second connection members connected in parallel to the first connection members are disposed at positions accessible from a front side of the uninterruptible power supply modules.

Abstract: A power converter includes a component compartment in which heat-generating components are housed, a duct for exhausting heat generated by the heat-generating components away from the component compartment, and a partition arranged between the component compartment and the duct in order to divide apart the component compartment and the duct. Outlets having sizes corresponding to the amounts of heat generated by the heat-generating components are formed in the partition.

Abstract: An uninterruptible power supply includes an input switch, an input filter, and a power converter disposed in this order, an output filter and an output switch disposed in this order from the power converter, and a plurality of conductors that connects the input switch, the input filter, the power converter, the output filter, and the output switch to each other in this order.
