Over-current Protection in Redundant Power Distribution Systems

Disclosed is a method and system for over-current protection in redundant power distribution systems.

In redundant power distribution systems, power is delivered through multiple paths to all powered equipment in the system. Failure of a power system component(s) along a certain path is tolerated by other system components on alternate path(s). This means that the current flowing into a certain component in normal running conditions is divided across each of the redundant paths. Upon failure of a power delivery path, its current is delivered through alternate paths to all equipment along the failing path.

Over-current protection in current power-distribution-systems is done statically by preventing the current flowing in each of the alternate paths to powered equipment from exceeding the rated-current of the equipment and conductors along each power distribution path. Since over-current protection guarantees safe operation of worst case current consumption, failure of all redundant paths except one doesn't trip an over-current mechanism. On the down side, a failing power supply that consumes double the current consumption due to aging components will go undetected due to the static nature of the over-current protection mechanism.

Disclosed is a dynamic over-current protection mechanism. Instead of statically setting of the each power delivery path to the maximum (equipment rated) current value, such...
