Title: AN ELECTRIC DISTRIBUTION ARCHITECTURE
Abstract:
An electric distribution architecture (10) may comprise a main bus (14) delivering current from a main source (12) to a set of distributed loads (24, 34) at a first voltage (20) wherein a subset (16) of the set requires a second voltage (30) lower than the first voltage (20). A distribution unit (32) may be connected between the main bus (14) and each load of the subset (16) and may include a voltage converter (36) converting the first voltage (20) to the second voltage (30). A battery bus (44) may deliver current to the subset at the second voltage from a battery (18) when the main bus is not operating. The battery bus may operate at a third voltage (40) higher than the second voltage (30) on the battery bus. The voltage converter may convert the third voltage to the second voltage for the subset when the main bus is not operating, wherein the battery bus has a weight adequate to accommodate a current at the third voltage.
