Abstract

An assembly and method for providing at multiphase current signals in which a plurality of conductors is arranged with conductors carrying dissimilar phases adjacent one another, and preferably in a balanced arrangement, such that the induced magnetic fields are subtractive from each other, and the assembly with reduced inductance results.

Claims

1. A current feeder assembly for feeding a 3-phase current signal from a source to a destination, said assembly comprising:

a plurality of insulated conductors configured to feed said 3-phase current signal, each conductor having a rectangular cross-section defined by four sides, the plurality of conductors provided in a rectangular array with said sides of adjacent conductors adjacent one another, the conductors arranged within the array such that said sides of a given conductor of the array feeding a given current phase are adjacent only conductors feeding the other two current phases.

2. The feeder assembly as in claim 1, wherein said plurality of conductors are provided in a pattern relative to the phases carried by the conductors, and wherein said pattern is repeated several times in said array.

3. The feeder assembly as in claim 1, wherein said conductors feeding said other two phases are provided in a balanced symmetrical pattern about said given conductor.

4. The feeder assembly as in claim 1, wherein said conductors feeding said other two phases are provided in numbers equal to one another.

5. The feeder assembly as in claim 1, wherein said array comprises a plurality of liner arrays, and wherein adjacent said linear arrays are partially offset relative to one another.

6. The feeder assembly as in claim 1, wherein said conductors comprise insulated printed circuits.

7. The feeder assembly as in claim 1, wherein said conductors each comprise a group of parallel conductor elements.

8. The feeder assembly as in claim 7, wherein parallel conductor elements are insulated from one another.

17. The feeder assembly as in claim 7, wherein said provided in an array having at least two rows.

18. The feeder assembly as in claim 7, wherein said rows are partially offset relative to one another.

9. A feeder assembly for feeding a multiphase current signal from a source to a destination, said assembly comprising:

a plurality of insulated conductors, each conductor having a perimeter and being configured for carrying one phase of said multiphase current signal, each given conductor of the plurality being bordered about said perimeter substantially by conductors of the plurality feeding phases dissimilar to a phase fed by said given conductor.

10. The feeder assembly as in claim 9, wherein said conductors are provided within the plurality in a phase pattern which is repeated several times.

11. The feeder assembly as in claim 9, wherein said conductors feeding said dissimilar phases are provided in a balanced symmetrical pattern relative to one another about said given conductor.

12. The feeder assembly as in claim 9, wherein said conductors feeding said dissimilar phases are provided in numbers equal to one another.

13. The feeder assembly as in claim 9, wherein said conductors each comprise a group of parallel conductor elements.

14. The feeder assembly as in claim 13, wherein said parallel conductor elements are insulated from one another.

15. The feeder assembly as in claim 9, wherein said conductors comprise insulated printed circuits.

16. The feeder assembly as in claim 9, wherein said conductors comprise rectangular insulated conductors.

19. A method of feeding a multiphase current signal comprising the steps of:

providing a plurality of conductors configured to feed the multiphase current signal; and

arranging the conductors relative to one another so that a magnetic field induced by current of a given phase passing through the conductors is substantially cancelled by magnetic fields induced by currents of dissimilar phases passing simultaneously through adjacent conductors.
