Abstract
An aircraft power generation unit to generate direct current (DC) power provided to a load includes a six-phase permanent magnet generator (PMG) and a rectifier section that converts alternating current (AC) voltage produced by the six-phase PMG into a DC output. The rectifier section includes a first six-pulse rectifier and a second six-pulse rectifier connected to the second set of windings. The unit also includes an output bus configured to be connected to the load and including a positive rail and a negative rail connected to the second rectifier and an output voltage regulation section that provides an output voltage to the output bus. The unit also include a controller that provides a pulse width modulated (PWM) signal to the output voltage regulation section to vary the output voltage provided to the output bus.
