A hybrid alternator includes a stator winding and a rotor winding. The stator winding includes a neutral point having a neutral point voltage and is preferably arranged as a three phase winding with the neutral point being located at the center junction of three stator winding portions arranged in a “Y”configuration. The rotor winding is mounted on a rotor which also includes permanent magnets. The rotor winding has a first end connected to the neutral point on the stator winding and a second end connected to a switching circuit. The rotor winding produces a magnetic flux field that additively combines with the permanent magnetic flux field from the permanent magnets when the switching circuit connects the second end of the rotor winding to a voltage greater than the neutral point voltage and produces a magnetic flux field that subtractively combines with the permanent magnetic flux field when the switching circuit connects the second end to a voltage less than the neutral point voltage.

A hybrid alternator comprising: a stator including a stator winding having a plurality of output ends connected through portions of the stator winding to a common neutral point having a neutral point voltage; and a rotor including: a shaft mounted for rotation within the stator, at least one permanent magnet mounted on the rotor producing a permanent magnetic flux field, a rotor winding mounted on the shaft and having a first end connected to the neutral point on the stator winding and a second end adapted for connection to a switching circuit in a voltage regulator, the rotor winding producing a rotor magnetic flux field that additively combines with the permanent magnetic flux field when the switching circuit connects the second end to a voltage greater than the neutral point voltage and producing a rotor magnetic flux field that subtractively combines with the permanent magnetic flux field when the switching circuit connects the second end to a voltage end to a voltage less than the neutral point voltage.
