Abstract:
1. An apparatus, comprising: plural alternators that are drivable by plural engines for producing AC electric currents; a rectifier in electrical communication with at least one of the alternators for producing a DC electric current; an inverter in electrical communication with the rectifier for producing a second AC electric current; the second AC electric current having at least one of a designated an acceptable frequency or a designated voltage, and the inverter in electrical communication with one or more electric loads responsive to the second AC electric current; an energy storage device that is able to electrically couple to at least one of the alternators, the rectifier, or the inverter; wherein one of the alternators comprises a generator system drivable by a constant-speed engine to produce one of the AC electric currents, the constant-speed engine being one of the plural engines; and the alternators being operable to produce at least one of voltages or the currents that are independent of one or more of the engine speeds or the power outputs.
