Abstract:
Provided is a method and system that includes a direct current solid state power controller that includes a plurality of switching devices connected in parallel for performing switching, one or more main transient voltage suppressors (TVSs) to perform voltage clamping, a plurality of parasitic inductances each connected in series with a switching device of the plurality of switching devices, and a plurality of local TVSs each connected in parallel with a series connection of a switching device and at least one parasitic inductor of the plurality of parasitic inductances, to dissipate energy stored within the at least one parasitic inductor of the plurality of parasitic inductances.
