Abstract

A bypass assembly. The bypass assembly includes a plurality of movable terminals configured to mate with fixed terminals of a power cell of a power supply. At least one of the movable terminals and its corresponding fixed terminal collectively form a contact when the at least one of the movable terminals and the corresponding fixed terminal are mated.

Claims

1. A bypass assembly, comprising:

a plurality of movable terminals configured to mate with fixed terminals of a power cell of a power supply,

wherein at least one of the movable terminals and its corresponding fixed terminal collectively form a contact when the at least one of the movable terminals and the corresponding fixed terminal are mated.

2. The bypass assembly of claim 1, wherein the at least one movable terminal comprises a jaw-like receptacle.

3. The bypass assembly of claim 2, wherein the jaw-like receptacle comprises at least one of the following:

a first jaw member; and

a second jaw member.

4. The bypass assembly of claim 1, further comprising a switching device connected between two of the movable terminals.

5. The bypass assembly of claim 4, wherein

a first of the two movable terminals is configured for connection to a secondary winding of a transformer, and

a second of the two movable terminals is configured for connection to another power cell of the power supply.

6. The bypass assembly of claim 4, wherein each of the two movable terminals are configured for connection to another power cell of the power supply.

7. The bypass assembly of claim 1, further comprising:

a first switching device connected between two of the movable terminals; and

a second switching device connected between one of the two movable terminals and another of the movable terminals.

8. The bypass assembly of claim 7, wherein:

a first of the two movable terminals is configured for connection to a secondary winding of a transformer;

a second of the two movable terminals is configured for connection to another power cell of the power supply; and

the another of the movable terminals is configured for connection to the another power cell of the power supply.

9. A power supply, comprising:

a plurality of power cells wherein at least one of the power cells comprises a plurality of fixed terminals; and

a plurality of bypass assemblies, wherein at least one of the bypass assemblies comprises a plurality of movable terminals configured to mate with the fixed terminals of the at least one power cell,

wherein at least one of the movable terminals and its corresponding fixed terminal collectively form a contact when the at least one of the movable terminals and the corresponding fixed terminal are mated.

10. The power supply of claim 9, wherein each bypass assembly corresponds to a different power cell.

11. The power supply of claim 9, wherein the at least one movable terminal comprises a jaw-like receptacle.

12. The power supply of claim 11, wherein the jaw-like receptacle comprises at least one of the following:

a first jaw member; and

a second jaw member.

13. The power supply of claim 9, further comprising a switching device The connected between two of the movable terminals.

14. The power supply of claim 13, wherein:

a first of the two movable terminals is configured for connection to a secondary winding of a transformer; and

a second of the two movable terminals is configured for connection to another power cell of the power supply.

15. The power supply of claim 13, wherein each of the two movable terminals are configured for connection to another power cell of the power supply.

16. The power supply of claim 9, further comprising:

a first switching device connected between two of the movable terminals; and

a second switching device connected between one of the two movable terminals and another of the movable terminals.

17. The bypass assembly of claim 16, wherein:

a first of the two movable terminals is configured for connection to a secondary winding of a transformer;

a second of the two movable terminals is configured for connection to another power cell of the power supply; and

power cell of the power supply.

18. The power supply of claim 9, wherein the power supply is a drive.
