Abstract
A system includes a soft DC power source having an output terminal, a DC load, a disconnect switch coupled between the output terminal of the DC power source and the DC load, and a capacitor coupled between a power side of the disconnect switch and a reference potential. The capacitor inhibits a rise in voltage across the disconnect switch as the disconnect switch is opening to inhibit arcing in the switch. Further, a disconnect switch assembly includes a pair of input terminals for coupling to a DC power source, a pair of output terminals for coupling to a DC load, a disconnect switch coupled between one of the input terminals and one of the output terminals, and a capacitor coupled between the pair of input terminals.
