Abstract: A hybrid alternator includes a stator (10) and a rotor (20), with the rotor (20) having longitudinally separate wound field (24) and permanent magnet (38) rotor portions. A rotor excitation circuit applies a forward polarity to the wound field rotor portion (24) to increase output in a boosting mode at low RPMs and a reverse polarity to decrease output at high RPMs in a bucking mode to maintain a constant voltage output. Alternative embodiments combine a magnetic flux concentrating design for efficient low speed operation with integral strength for high speed capability. Dual voltage output is provided using only one stator winding. A three state voltage regulator allows voltage regulation without inducing reverse currents onto the power bus in the lightly loaded or no battery conditions. The regulator has automatic interlocking to automatically turn on and off without risk.

Abstract: A hybrid alternator comprising a stator (702) and a rotor (710) mounted for rotation within the stator and separated therefrom by an air gap. The rotor has a rotor core defining a plurality of magnetic poles (716) wherein adjacent ones of the magnetic poles have alternating north and south magnetic fields. The plurality of magnetic poles comprises a plurality of permanent magnet poles (716a, 716b) and a plurality of electromagnetic poles (716). Each permanent magnet pole is defined by a permanent magnet (718). The plurality of permanent magnet poles comprises two (2) sets of diametrically positioned permanent magnet poles. The hybrid alternator also includes a temperature monitoring voltage regulator that provides protection against overheating damage while permitting the alternator to significantly exceed its rated output for short periods of time or in colder ambient temperatures.
