Abstract: A system for detecting latent defects within a redundant power architecture includes a plurality of redundant power supplies, each having one or more output power rails, connected in a redundant fashion to a system load; each power supply output having fault-isolating OR'ing circuitry that prevents reverse current flow when free of defects; each power supply having means for adjusting its output voltage; each power supply having means for monitoring an internal voltage therein, and, based on characteristics of the monitored internal voltage, determining the presence of latent defect/s in the fault-isolating “OR'ing” circuitry. Further, the system operates to shift the load demanded from power supplies in redundant power architectures to allow the power supplies to run at their optimum electrical efficiency.

Abstract: A system and method for determining power use in a system are disclosed. Briefly described, one embodiment of a method comprises metering power flow into a metered front end rectifier system using a metering circuit residing in the metered front end rectifier system and coupled to an alternating current (AC) power source, determining information corresponding to the metered power flow and communicating the determined metered power flow information to a user interface.

Abstract: A monitor system and method are described for sensing voltage changes in a plurality of transistors of a multiphase circuit comprising a sensor connected to each one of the plurality of transistors for measuring a voltage drop across the each one, a difference detector for comparing the voltage drop to a previous voltage drop attributable to the each one of the plurality of transistors, and a driver circuit for controlling a state of the plurality of transistors, wherein the driver circuit deactivates one or more of the plurality of transistors when the voltage drop varies from the previous voltage drop by a predefined amount.
