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.

Abstract: A power generating system includes a high-frequency alternator, a rectifier, a capacitor in each phase line extending between an output terminal of the alternator and the rectifier, and an auxiliary power supply, providing auxiliary power for use within the power generating system, which is also connected to the output terminals of the alternator.
