Abstract:
1. An electric power system which includes an alternator comprising: (1) a case made of magnetic material; (2) at least one conventional stator winding with laminations within the case; (3) a solid rotor having at least two lobes made of magnetic material, the lobes protruding outward from the rotor, and said rotor capable of rotating relative to the stator with an air gap between said stator and said rotor; (4) a field winding adjacent to said stator capable of polarizing said lobes on said rotor such that said lobes have a north pole at one end and a south pole at the other end; (5) said rotor being capable of being driven by at conventional prime mover at any speed from very low to very high; (6) said rotor moving relative to said stator giving a polyphase current output; and (7) a solid state switching device capable of converting the polyphase current output to any frequency; whereby the polyphase current output from the alternator may be converted to any appropriate frequency for conventional electric power use either stand alone or synchronized with the power grid.
