ABSTRACT:
Systems and methods for providing AC power from multiple turbine engine spools are disclosed. A system in a particular embodiment includes a turbofan engine having a compressor, a first turbine and a first shaft connected between the compressor and the first turbine, and a fan, a second turbine and a second shaft connected between the fan and the second turbine. The system can further include a state power bus and a first energy converter coupled between the first shaft and the power bus, with the first energy converter including a starter/generator, and being positioned to convert a first variable frequency energy transmitted by the first shaft to a first generally constant frequency energy. A second energy converter can be coupled between the second shaft and the power bus, with the second energy converter including a generator and being positioned to convert a second variable frequency energy transmitted by the second shaft to a second generally constant frequency energy, with the second generally constant frequency energy in phase with and at generally the same frequency as the first generally constant frequency energy. A controller can be operatively coupled to the starter/generator and the generator, e.g., to control the functions of these devices.
