Abstract:
1. A modular system that provides backup electrical power to telecommunications equipment via a pressurized air driven turbine operating in cooperation with a generator that are initiated by a control system, wherein the electrical power is presented at a voltage level appropriate for the telecommunications equipment, said system comprising: a first conversion device for converting alternating current (AC) from an AC utility into a primary source of direct current (DC) fed into a DC bus; the turbine operable to utilize the pressurized air to create mechanical energy; the generator for converting the mechanical energy created by the turbine to AC; a second conversion device for converting AC from the generator into DC that is introduced to the DC bus when a power drop exists in the utility AC; an energy-storage device for automatically introducing DC to the DC bus as a bridge during a switch between the AC utility to the turbine; the DC bus that is electrically linked to the first conversion device, the second conversion device, and the energy-storage device in parallel, and conveys DC to the BTS equipment; and a housing in which the first conversion device, the energy-storage device, the turbine and the generator are located, wherein the housing encloses the BTS equipment within an internal cabinet, and where the BTS equipment supports communication from a communications tower.
