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.
