Abstract

A distributed converter for delivering power to a set of loads is provided. The distributed converter includes a converter battery distribution unit that includes a converter-modular power tile, and the converter-modular power tile includes a battery pack configured to deliver power to a load of the set of loads.

First claim

The invention claimed is:

1. A distributed converter for delivering power to a set of loads, the distributed converter comprising:
a set of converter battery distribution units, each converter battery distribution unit of the set of converter battery distribution units (i) being connected to one or more corresponding loads of a set of loads; (ii) being configured to deliver power to the one or more corresponding loads of the set of loads; and (iii) including:
a converter-modular power tile; and
a battery pack being directly connected to the converter-modular power tile and including one or more modules of batteries, each module configured to match and deliver power to a dedicated load of the one or more corresponding loads connected to the converter battery distribution unit.

2. The distributed converter of claim 1 , wherein the battery pack is a modular battery pack.

3. The distributed converter of claim 1 , wherein a module of the battery pack includes one or more batteries selected to match the load.

4. The distributed converter of claim 1 , wherein the distributed converter is configured to perform power conversion from about 115 V AC to 28 V DC.

5. The distributed converter of claim 1 , wherein the distributed converter is configured to support voltages including 270V, +/−270V, and 540 V.

6. The distributed converter of claim 1 , further comprising a bus configured for power delivery from the battery pack to the load.

7. The distributed converter of claim 1 , further comprising a switch configured to either isolate or connect a battery of the battery pack to the load.

8. The distributed converter of claim 1 , further comprising a charging circuit configured to charge a battery included in the battery pack.

9. The distributed converter of claim 1 , further comprising a redundant converter battery distribution unit configured similarly to the converter battery distribution unit.

10. The distributed converter of claim 9 , wherein the redundant converter battery distribution unit is connected to the converter battery distribution unit via a switched connection.

11. A distributed converter for delivering power to a set of loads in a vehicle, the distributed power converter comprising:
a set of converter battery distribution units dispersed around the vehicle, each converter battery distribution unit of the set of converter battery distribution units (i) being connected to one or more corresponding loads of a set of loads; (ii) being configured to deliver power to the one or more corresponding loads of the set of loads; and (iii) including: a converter-modular power tile; and
a battery pack being directly connected to the converter-modular power tile and including one or more modules of batteries, each module configured to match and deliver power to a dedicated load of the one or more corresponding loads connected to the converter battery distribution unit.

12. The distributed converter of claim 11 , wherein the battery pack is a modular battery pack.

13. The distributed converter of claim 11 , wherein a module of the battery pack includes one or more batteries selected to match a connected load.

14. The distributed converter of claim 11 , wherein the distributed converter is configured to perform power conversion from about 115 V AC to 28 V DC.

15. The distributed converter of claim 11 , wherein the distributed converter is configured to support voltages including 270V, +/−270V, and 540 V.

16. The distributed converter of claim 11 , further comprising a bus configured for delivery of power from a battery of the battery pack to the associated load.

17. The distributed converter of claim 11 , further comprising a switch configured to either isolate or connect a battery of the battery pack to the associated load.

18. A distributed converter for delivering power to a set of loads dispersed throughout a vehicle, the distributed power converter comprising:
at least one converter battery distribution unit in each section of the vehicle, the at least one converter battery distribution unit (i) being connected to one or more corresponding loads of a set of loads; (ii) being configured to deliver power to the one or more corresponding loads of the set of loads; and (iii) including: a converter-modular power tile; and
a battery pack being directly connected to the converter-modular power tile and including one or more modules of batteries, each module configured to match and deliver power to a dedicated load of the one or more corresponding loads connected to the converter battery distribution unit configured to deliver power to a load from the set of loads.

19. The distributed converter of claim 18 , wherein the at least one converter battery distribution unit is interfaced with a redundant converter battery distribution unit configured similarly to the at least one converter battery distribution unit.

20. The distributed converter of claim 19 , wherein the at least one converter battery distribution unit is interface with the redundant converter battery distribution unit via a switched connection.
