A basic redundant power architecture that might be used in high-end systems likeservers & telecom and communications infrastructure equipment essentially comprises two or more power sources driving a load. ORing solutions are required to protect the redundant bus and the system in the event one input power source fails. Redundant power architectures are used on a variety of different bus voltages, depending on the type of end system, typically including low voltage 5 V, 3.3 V, 2.5 V and PICOR WHITE PAPER Active ORing Solutions in Redundant Power System Architectures Contents Page A basic redundant power architecture that might be used in high-end systems like servers & telecom and communications infrastructure equipment essentially comprises Active ORing 1 Solutions Dramatically two or more power sources driving a load.
