Abstract: A power supply system includes an AC input interface, a DC output interface, and each of a single-conversion power supply path and a multi-conversion power supply path extending between the AC input interface and the DC output interface. Operating the system in a first or standard mode includes conveying electrical power between an AC power supply and an electrical load by way of the single-conversion power supply path. Operation in a second or non-standard operation mode includes conveying the electrical power by way of the multi-conversion power supply path.

Abstract: An uninterruptible power supply system includes an AC input interface and a DC output interface, and a plurality of power supply paths coupled between the AC and DC interfaces. A first one of the power supply paths has a lower component count, whereas a second one of the power supply paths has a higher component count. At least one of the power supply paths is structured to supply DC electrical power to a power bus in the DC output interface at a varying voltage.
