Abstract: A direct current (DC) power system includes a plurality of energy sources supplying power to a plurality of loads via a DC bus having at least one positive rail. The DC bus includes two DC bus subsections and a DC bus separator coupled between the two DC bus subsections. The DC bus separator includes a controllable switch with at least one of its terminals coupled with a terminal of an inductor to provide a current path between the two DC bus subsections during normal operation via the inductor. The controllable switch is switched off to break the current path when a fault on the positive rail is detected. Furthermore, the DC bus separator includes a diode connected in parallel to the inductor and arranged to provide a circulating current path to dissipate an inductor current in the inductor when the controllable switch is switched off.
