Methods and apparatuses are disclosed for producing current with a desired output frequency from one or more fixed or variable speed alternators by varying a saturation level of a portion of the alternator(s) based on a output frequency desired, and preferably then rectifying the output to produce a desired electrical output which may be provided as direct current or alternating current to a suitable load.
The invention claimed is: 1. An apparatus comprising: a first alternator and a second alternator, each alternator having a rotor and stator, the stator having a plurality of rotor magnetic circuits co-operatively defined between the stator and rotor and a plurality of secondary magnetic circuits, each rotor magnetic circuit encircling a first portion of at least one power winding of the stator, each secondary magnetic circuit encircling a second portion of the power winding disposed outside the rotor magnetic circuits, at least one control winding assoc...
