摘要： A controller (500) in an electric drive system is used to develop power generation failure diagnostics. During operation, the controller (500) receives a set of generator inputs, a set of machine parameters, and a set of diagnostic values. Next, the controller (500) determines a set of expected operating values corresponding to the set of diagnostic values. The controller (500) then compares the obtained diagnostic values to one or more corresponding expected operating values. If the difference is greater than a threshold, the controller (500) provides an appropriate fault indication.

摘要： A system for detecting a short circuit in a direct current (DC) link (312), wherein the DC link (312) is coupled with a rectifier (206) which includes a set of rectifier diode pairs (310). During operation, a controller (500) receives a set of inputs from a power generator 204, a set of machine parameters, and a set of diagnostic values. Next, the controller (500) determines a set of expected operating values corresponding to the set of diagnostic values. The controller (500) then compares diagnostic values to corresponding expected operating values. If the difference between the diagnostic values and the expected operating values exceeds a threshold, the controller (500) provides a flag to indicate that a short circuit condition exists.

摘要： A controller (500) in an electric drive system is used to determine the operating condition of array of rotating diodes (302B) within a generator (204). During operation, the controller (500) receives a set of generator inputs, a set of machine parameters, and a set of diagnostic values. Next, the controller (500) determines a set of expected operating values corresponding to the set of diagnostic values. The controller (500) then compares the obtained diagnostic values to one or more corresponding expected operating values. If the difference is greater than a threshold, the controller (500) provides a fault indication that one or more of the array of rotating diodes (302B) has malfunctioned.
