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.
