Abstract
Abstract Aspects for reporting faults in a redundant power converter are described. An exemplary method aspect includes monitoring at least one node within the redundant power converter. The method further includes tracking values of the at least one node during a predetermined time period, and predicting when a specification of the redundant power converter will be exceeded based on the tracked values.

Total Claims: 15
Claim 1
Independent Claim
60 words
A method for reporting faults in a redundant power converter, the method comprising the steps of: (a) monitoring at least one node within the redundant power converter; (b) tracking values of the at least one node during a predetermined time period; and (c) predicting when a specification of the redundant power converter will be exceeded based on the tracked values.
Claim 2
Independent Claim
60 words
A method for reporting faults in a redundant power converter, the method comprising the steps of: (a) monitoring at least one node within the redundant power converter; (b) tracking values of the at least one node during a predetermined time period; and (c) predicting when a specification of the redundant power converter will be exceeded based on the tracked values.
Claim 3
Dependent Claim
20 words
The method of claim 1 further comprising performing the steps (a), (b), and (c) within a system management interface controller.
Claim 4
Dependent Claim
17 words
The method of claim 2 wherein the performing within the system management interface controller occurs via microprogramming.
Claim 5
Dependent Claim
25 words
The method of claim 1 wherein the step (c) of predicting further comprises predicting when a fault due to long term thermal drift will occur.
Claim 6
Dependent Claim
28 words
The method of claim 1 wherein the step (c) of predicting further comprises predicting when a fault due to component wearout within the redundant power converter will occur.
Claim 7
Independent Claim
71 words
A system for reporting faults in a redundant power converter, the system comprising: at least two redundant power converters coupled in parallel to a sensitive load; and a system manager interface controller coupled to the at least two redundant power converters for reporting a status of the at least two redundant power converters for prediction of when one or more of the at least two redundant power converters will exceed specification.
Claim 8
Independent Claim
71 words
A system for reporting faults in a redundant power converter, the system comprising: at least two redundant power converters coupled in parallel to a sensitive load; and a system manager interface controller coupled to the at least two redundant power converters for reporting a status of the at least two redundant power converters for prediction of when one or more of the at least two redundant power converters will exceed specification.
Claim 9
Dependent Claim
36 words
The system of claim 6 wherein the system management interface controller further monitors at least one node within the redundant power converter, and tracks values of the at least one node during a predetermined time period.
Claim 10
Dependent Claim
24 words
