Abstract
Unique systems, methods, techniques and apparatuses of an exciterless synchronous generator are disclosed. One exemplary embodiment is an exciterless synchronous generator comprising a stator, a rotor, and a startup excitation system. The stator includes a set of stator windings. The rotor includes an energy harvest winding, a DC power supply including a DC bus and coupled to the energy harvest winding, and a field winding coupled to the DC power supply. The startup excitation system comprises one of a magnetic field generation system structured to generate a magnetic field received by the energy harvest winding in response to a rotation of the rotor, wherein the magnetic field is converted to DC power with the DC power supply and transmitted to the field winding; or a rotor DC power source including and diode coupled in series across the DC bus.
