Abstract
A system for bypassing a power cell of a power supply, the system including 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, and a bypass device connected to first and second input terminals of at least one of the power cells and to first and second output terminals of the at least one of the power cells.
Claims18
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;
- and
- a bypass device connected to first and second input terminals of at least one of the power cells and to first and second output terminals of the at least one of the power cells.

A method, comprising:
- determining that a failure has occurred in a power cell of a multi-cell power supply;
- and
- applying a pulse of current from a control circuit to a solenoid which is coupled to the following:
- a first contact which is connected to a first input terminal of the power cell;
- a second contact which is connected to a second input terminal of the power cell;
- and
- a third contact which is connected to first and second output terminals of the power cell.
