First Claim
Patent Images
1. A method of bypassing a power cell in a multi-cell power supply, comprising:
- determining that a failure has occurred in a first power cell of a multi-cell power supply;
moving a part of a first contact which is connected to first and second output terminals of the first power cell from a first position to a second position such that either the first or the second output terminals are disconnected from the multi-cell power supply;
moving a part of a second contact which is connected to a first input terminal of the first power cell from a third position to a fourth position such that the first input terminal is disconnected from the multi-cell power supply; and
moving a part of a third contact which is connected to a second input terminal of the first power cell from a fifth position to a sixth position such that the second input terminal is disconnected from the multi-cell power supply.

16. A system, comprising:
-
a multi-winding device having a primary winding and a plurality of three-phase secondary windings; a plurality of power cells, wherein each power cell is connected to a different three-phase secondary winding of the multi-winding device; a first contact connected to a first input terminal of a first power cell and configured to disconnect the first input terminal of the first power cell from the multi-winding device; a second contact connected to a second input terminal of the first power cell and configured to disconnect the second input terminal of the first power cell from the multi-winding device; and a third contact connected to first and second output terminals of the first power cell and configured to disconnect either the first or the second output terminals of the first power cell from the multi-winding device. - View Dependent Claims (17)
