Abstract
An apparatus including an alternator that is drivable by an engine for producing a first AC electric current, a rectifier in electrical communication with the alternator for producing a DC electric current, an inverter in electrical communication with the rectifier for producing a second AC electric current where the second AC electric current having an acceptable frequency and/or voltage, and the inverter in electrical communication with one or more electric loads responsive to the second AC electric current, and an energy storage device that is able to electrically couple to the alternator, rectifier, and/or inverter.
Claims21
An apparatus, comprising:
- an alternator that is drivable by an engine for producing a first AC electric current;
- a rectifier in electrical communication with the alternator 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 an acceptable frequency and/or voltage, and the inverter in electrical communication with one or more electric loads responsive to the second AC electric current;
- and
- an energy storage device that is able to electrically couple to the alternator, rectifier, and/or inverter.
An apparatus, comprising:
- a plurality of alternators each driven by a respective variable speed engine for producing a respective first AC electric signal;
- a plurality of rectifiers each in electrical communication with a respective one of the alternators for producing a respective DC electric signal;
- a DC bus connected to an output of at least one of the rectifiers;
