Patent ID: 8310211

Claim:
An apparatus for converting energy from a rotating source of mechanical energy into electrical energy comprising: an alternator comprising: two Lundell type high voltage dual claw pole rotor assemblies keyed on a common shaft adapted to be connected to a source of rotating mechanical energy, the rotor assemblies being oriented North-South-South-North from end to end and having a gap of a predetermined size therebetween to enable the rotor assemblies to develop independent magnetic fields, the rotor assemblies mounted inside a housing containing a single cylindrical stator having multiple windings, each winding being wound through two separate laminated steel sections with a gap between each of the stator windings, each stator winding being configured to operate in phase with the other stator winding; a three-phase high-voltage alternating current wye (Y) output; and a high-voltage direct current field winding connected to the rotor and having a positive connection and a negative connection; and an energy control module comprising: a switch mode rectifier having: an input connected to the wye (Y) output of the alternator; a three-phase rectifier for receiving power from the wye (Y) output and rectifying the power to direct current; a buck converter that takes the direct current from the three-phase rectifier and reduces the direct current input voltage to a predetermined direct current output voltage; a positive output connected to the positive connection of the direct current field of the alternator; and a negative return; a pulse width modulation controller comprising a high-frequency pulse width modulation switch connected between the negative return and the negative connection of the direct current field winding; and a multi-stage feedback loop connected to the wye (Y) output and configured to monitor the voltage level of the wye (Y) output and use that information to control the pulse width modulation switch and thereby control generation of power using the alternator and maintain the voltage on the wye (Y) output at a first predetermined voltage.
