1. A system comprising:
- an electrical load comprising circuits performing telecommunications functions;
a primary source of electrical power, providing direct current to the electrical load;
a first voltage sensing circuit determining when a failure of the primary source occurs;
a backup source of electrical power, providing direct current, including a microturbine power generating system, wherein the microturbine power generating system includes a microturbine, an alternator driven by the microturbine, and a rectifier,a first relay, switching the electrical load from the primary source to the backup source in response to a determination within the first voltage sensing circuit that a failure of the primary source has occurred.

Abstract
A system includes an electrical load formed by a number of circuits within a system performing telecommunication functions, primary and backup sources of electrical power, and a relay that switches an input to the electrical load from the primary source to the backup source in response to determining that a failure has occurred within the primary source. The backup source includes a microturbine driving a six-phase, high-frequency alternator, which is turned on in response to determining that such a failure has occurred, and, preferably, a battery array that provides backup power when adequate power is not available from the alternator driven by the microturbine.
