Abstract
An aircraft power generation unit to generate power provided to a load includes a permanent magnet generator (PMG) that includes first, second, third and fourth sets of windings, each of the winding sets including three windings and a control coil and a rectifier section that includes first through third six pulse rectifiers, a DC to DC to converter and a common local output bus. The unit also includes an output bus configured to be connected to the load and including a positive output bus rail and a negative output bus rail, wherein the negative output bus rail is connected to the negative output of the DC to DC converter and a controller that receives an input signal from at least one of the output sets and selectively couples the DC to DC converter and one or more of the first, second and third six-pulse rectifiers to the output bus.
