Abstract
A dual source electric power generating system (EPGS) provides both a regulated AC output and a regulated DC output. The EPGS includes a rotating portion and a stationary portion. The stationary portion includes a plurality of windings (permanent magnet generator (PMG) armature windings, an exciter field winding, and high-voltage main generator armature windings), a voltage regulator, a rectifier, an inverter, a point of regulation (POR) sensor. The high-voltage main generator armature windings generate a high-voltage AC that is converted to a regulated, high-voltage AC by the rectifier and the inverter. The stationary portion is further characterized by circuitry for producing the regulated DC output from AC voltage produced by a winding other than the high-voltage main generator armature windings.
