There are apparatus and methods for generating a plurality of voltage levels. There is a rotor that includes a first and a second portion of rotor windings. The first portion of rotor windings is constructed and arranged to establish a first magnetic field of a first number of poles. The second portion of rotor windings is constructed and arranged to establish a second magnetic field of a second number of poles. A stator is disposed adjacent the rotor. The stator includes a first and a second portion of stator windings. The first portion of stator windings is related to the first number of poles and has a first output port configured for furnishing an electrical output at a first voltage level. The second portion of stator windings is related to the second number of poles and has a second output port configured for furnishing an electrical output at a second voltage level.
