Patent ID: 8729732

Claim:
A system for generating power, comprising: a communications interface configured to communicatively couple a wireless interface to a telecommunications back-haul; multiple power sources, each coupled to the communications interface, wherein the multiple power sources include: a primary power interface configured to provide power from a primary power source to the communications interface; a back-up generator, wherein the back-up generator is configured to be selectively enabled to generate power and to provide generated power to the communications interface, to a battery circuit, or both; and the battery circuit, wherein the battery circuit is configured to selectively provide power to the communications interface; a rectifier and switch circuit, coupled to the each of the multiple power sources, and configured to selectively switch power from among the multiple power sources and from the multiple power sources to the communications interface, wherein the rectifier and switch circuit includes: multiple rectifiers selectively coupled to the commercial power interface and the back-up generator, and configured to selectively rectify power from the commercial power interface or from the back-up generator; and a power controller, coupled to the rectifier and switch circuit and at least the back-up generation, wherein the power controller is configured to individually enable and disable multiple rectifiers based, at least in part, on an availability status of the primary power source; and wherein the power controller is configured to control the switching of the rectifier and switch circuit and to enable and disable the back-up generator.
