Abstract

A localized source selection and power conversion power distribution system is described herein. In contrast to legacy systems, where multiple bus tie connectors are coupled between the centralized buses, the localized source selection and power conversion power distribution system is, in general, solely linked by a post conversion link. The localized source selection and power conversion power distribution system is also configured to effectively balance the loads of the aircraft. For example, that any power district can draw power from any power source at any time.

Claims

1. A localized power distribution system comprising:

power block coupled to a plurality of power sources comprising;

a source selection module; and

localized converters electrically coupled to the source selection module, wherein the power block is configured to perform power source selection, power conversion and power distribution to a plurality of end loads.

2. The localized power distribution system of claim 1, wherein the plurality of power sources to the localized power distribution system provide at least one of alternating current or direct current.

3. The localized power distribution system of claim 1, wherein the plurality of power sources to the localized power distribution system are at least one of a generator, an auxiliary generator, or a ram air turbine, fuel cell, solar array, battery or other power generation/storage device.

4. The localized power distribution system of claim 1, wherein the localized converters comprise at least one of an inverter or a converter.

5. The localized power distribution system of claim 1, wherein the power block further comprises bus power control unit data processing capabilities.

6. The localized power distribution system of claim 1, further comprising a plurality of virtual essential busses.

7. The localized power distribution system of claim 1, further comprising a coupling to an aircraft data network and a private communication network,

wherein the aircraft data network is a communication system for communications with an avionics system, and

wherein the private communication network is configured for transmitting communications to the localized power distribution system.

8. The localized power distribution system of claim 1, wherein the localized power distribution system is disposed on a vehicle.

9. The localized power distribution system of claim 1, wherein the plurality of end loads coupled to the power block are logically grouped.

10. A method comprising:

selecting a power source, from a plurality of power sources, to provide power via a source selection module;

receiving the power from the power source;

converting the power to a desired voltage and frequency; and

distributing the converted power to an end load.

11. The method of claim 10, wherein the plurality of power sources are at least one of a generator, an auxiliary generator, or a ram air turbine, fuel cell, solar array, battery or other power generation/storage device.

12. The method of claim 10, wherein the converting is performed by at least one of an inverter or a converter.

13. The method of claim 10, wherein the end load is coupled to a virtual essential bus.

14. The method of claim 10, wherein the source selection module is disposed on a vehicle.

15. The method of claim 10, wherein the source selection module is grouped with a power block, wherein the power block comprises bus power control unit data processing capabilities.
