Abstract:
1. An apparatus comprising: a first alternator coupled with a first variable speed engine to produce a first alternating electric current; a second alternator coupled with a second variable speed engine to produce a second alternating electric current; a first rectifier in electrical communication with at least one of the first alternator or the second alternator for producing a first direct electric current from the first alternating electric current and the second alternating electric current; an inverter in electrical communication with the first rectifier for producing a third alternating electric current, the inverter in electrical communication with one or more electric loads to supply the third alternating electric current to the one or more electric loads; a first energy storage device electrically coupled to at least one of the first alternator, the second alternator, the first rectifier, or the inverter; and a controller for controlling the first alternator and the second alternator, wherein the first alternator is controlled by the controller independent of the second alternator such that the first alternating electric current produced by the first alternator is equal to the second alternating electric current produced by the second alternator when the first variable speed engine and the second variable speed engine operate at different speeds, the controller for controlling the inverter such that the third alternating electric current has at least one of a designated frequency or a designated voltage.
