Abstract:
1. A direct current (DC) power distribution system, comprising: a first electrical distribution and power management (EDPM) unit comprising a first DC power source, the first DC power source connected to a first high voltage DC bus connected to a first DC load, and a first bus-tie solid state power controller (SSPC), the first bus-tie SSPC being connected to the first HVDC bus; a second EDPM unit comprising a second DC power source, the second DC power source connected to a second high voltage DC bus connected to a second DC load, and a second bus-tie SSPC, the second bus-tie SSPC being connected to the second HVDC bus; and a bus-tie connected between the first bus-tie SSPC and the second bus-tie SSPC, wherein in the event a power source failure occurs in the first EDPM unit, power flows from the second DC power source to the first HVDC bus via the second bus-tie SSPC, the bus-tie, and the first bus-tie SSPC; wherein the first and second bus-tie SSPCs each comprise a power switch, each power switch comprising a field effect transistor (FET) connected across a Schottky diode.
