Controller for a locomotive
A power system for a locomotive. The power system has a first power unit, a second power unit, a first inverter configured to power the first power unit or the second power unit, a second inverter configured to power the first power unit or the second power unit. Further the power system has a first controller selectively coupled to one of the first inverter or the second inverter to control the operation of the first inverter or the second inverter and a second controller selectively coupled to one of the first inverter or the second inverter to control the operation of the first inverter or the second inverter.

a second controller selectively coupled to one of the first inverter or the second inverter to control the operation of the first inverter or the second inverter.
2. The power system of claim 1 wherein the first controller and the second controller have a first mode of operation and a second mode of operation.
3. The power system of claim 1 wherein the first controller in the first mode of operation is configured to couple with the first inverter and controls the operation of the first inverter.
4. The power system of claim 1 wherein the first controller in the second mode of operation is configured to couple with the second inverter and control the operation of the second inverter.
5. The power system of claim 1 wherein the second controller in the first mode of operation is configured to couple with the second inverter and control the operation of the second inverter.
6. The power system of claim 1 wherein the second controller in the second mode of operation is configured to couple with the first inverter and control the operation of the first inverter.
7. The power system of claim 1 further comprising a third power unit.
8. The power system of claim 7 further comprising a third inverter configured to power the first power unit, second power unit or third power unit.
9. The power system of claim 8 further comprising a third controller selectively coupled to one of the first inverter, second inverter or third inverter to control the operation of the first inverter, second inverter or third inverter.
10. A locomotive comprising:
a power system, the power system comprising:
a first power unit;
a second power unit;
a first inverter configured to power the first power unit or the second power unit;
a second inverter configured to power the first power unit or the second power unit;
a first controller selectively coupled to one of the first inverter or the second inverter to control the operation of the first inverter or the second inverter; and
a second controller selectively coupled to one of the first inverter or the second inverter to control the operation of the first inverter or the second inverter.
