POWER DISTRIBUTION SYSTEM FOR AN AIRCRAFT

摘要

An aircraft power distribution system (22) includes at least one DC power source, a first DC power distribution bus and a second DC power distribution bus (36), a tie bus (33) coupling the at least one DC power source, first DC power distribution bus, and second DC distribution bus, wherein the first or second DC power distribution buses are selectively coupled and decoupled to the tie bus by means of a solid-state poer controller (SSPC) (46, 48, 62, 64, 66).

1. An aircraft power distribution system, comprising:
at least one DC power source; a first DC power distribution bus and a second DC power distribution bus; a tie bus coupling the at least one DC power source, first DC power distribution bus, and second DC power distribution bus; a first solid state power controller located in-line on the tie bus between the first DC power distribution bus and the at least one DC power source; a second solid state power controller located in-line between the second DC power distribution bus and the at least one DC power source; and each of the first and second solid state power controllers 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, the first or second solid state power controller selectively couples and decouples the respective first or second DC power distribution buses to the tie bus.
