Claim:
1. An aircraft power distribution system, comprising: a first DC power distribution bus, a second DC power distribution bus, and a third DC power distribution bus; a DC power source coupled with at least one of the first, second, or third DC power distribution buses; a set of electrical couplings, wherein electrical couplings included in the set are coupled between the first, second, and third DC power distribution buses, and the set of electrical couplings enable transmission of power between the first, second and third DC power distribution buses; and a solid state power controller positioned in-line on each electrical coupling, each solid state power controller comprising two power switches in a back-to-back configuration, each power switch comprising a field-effect transistor (FET) connected across a Schottky diode; wherein a configuration of the first, second and third DC power distribution buses and the solid state power controllers defines a ring-type bus configuration, and the solid state power controllers selectively couple and decouple the first, second, and third DC power distribution buses across the set of electrical couplings.
