ABSTRACT:
A reliable power supply solution for a telecommunications site provides a combined primary and backup source of electrical power. One system of the power supply solution includes one or more microturbine generators operable to produce AC electrical power as well as one or more rectifiers operable convert the AC electrical power from the one or more microturbine generators to DC electrical power for supply to a DC bus. A transfer switch is electrically coupled between one or more microturbine generators and the one or more rectifiers, for selecting between the AC electrical power of the microturbine generators and incoming AC electrical power to be supplied to the rectifiers. Additionally, one or more proton exchange membranes are provided in the system for producing DC electrical power. The aforementioned power generation and supply components are coupled with the DC bus for supplying DC electrical power to telecommunications equipment coupled with the DC bus.
