ABSTRACT:
A redundant power supply method is provided. The method includes communicatively coupling a load to a first source via a plurality of first power supplies and to a second source via a plurality of second power supplies. The method further includes bi-directionally communicatively coupling a controller to the plurality of first power supplies and to the plurality of second power supplies. The method includes activating a first portion of the plurality of first power supplies to supply power to the load, wherein the controller determines the number (“N”) of first power supplies activated, and activating at least one of the plurality of second power supplies to supply power to the load. The method also includes monitoring for at least one fault condition in each of the active first power supplies and in each of the active second power supplies.
