Voltage regulation of multi-phase permanent magnet generator

A method of providing direct current (DC) power provided to a load, the method comprising:

• generating alternating current (AC) power with a permanent magnet generator (PMG) that includes first, second third and fourth sets of windings, each of the sets of winding including three windings;
• converting the AC power produced by the PMG into a DC output, with a rectifier section that includes:
• a first six-pulse rectifier connected to the first set of windings and having a first rectifier positive rail and first rectifier negative rail;
• a second six-pulse rectifier connected to the second set of windings and having a second rectifier positive rail and a second rectifier negative rail;
• a third six-pulse rectifier connected to the third set of windings and having a third rectifier positive rail and a third rectifier negative rail;
• a fourth six-pulse rectifier connected to the fourth set of windings and having a fourth rectifier positive rail and a fourth rectifier negative rail;
• a DC to DC converter connected across the fourth rectifier positive rail and the fourth rectifier negative rail;
• and
• a common local output bus;
• coupling the DC to DC converter to an output bus negative rail;
• and
• selectively coupling with a controller based on an input signal from at least one of the output sets one or more of the first, second and third six-pulse rectifiers to an output bus positive rail to provide a constant voltage to the load, wherein the controller selectively couples the one or more of the first, second and third six-pulse rectifiers to the common local output bus based on a speed of the PMG.
