Abstract: Aspects for sensing faults in a redundant power converter are described. An exemplary circuit aspect includes a signal transition monitor for monitoring signal transitions at a predetermined node within the redundant power converter, and a detector for detecting a fault condition in the redundant power converter when a proper signal transition fails to occur during a base period of switching. The aspects sense faults in a manner which allows replacement during a scheduled downtime, so that redundancy is restorable without having an unscheduled outage.

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.

Abstract: Aspects for isolating faults in a redundant power converter are described. An exemplary system aspect includes a first switch at an input of the redundant power converter for protecting the redundant power converter from a high input voltage, and a second switch coupled within the redundant power converter prior to an output capacitor, wherein efficiency of fault isolation is improved.

Abstract: A linear voltage regulator for regulating the voltage and current in a DC supply is described. The invention includes current and voltage sense elements. The outputs from the sensed elements are summed together as the gate input to an FET pass transistor which regulates the power supplied. The two feedback loops provide high bandwidth and improve dynamic response.
