| 1. A permanent magnet generator voltage regulation system for a permanent magnet generator (PMG) having stator coils, the
voltage regulation system comprising:
means for monitoring an output voltage generated by the PMG;
a switch array having switches connected to the stator coils; and
a controller that selectively opens and closes the switches in the switch array based on the monitored output voltage to connect
the stator coils in either a first stator coil configuration, a second stator coil configuration, or a third configuration,
wherein the output voltage generated with the stator coils in the first configuration is greater than the output voltage generated
with the stator coils in the second configuration, and the output voltage generated with the stator coils in the second configuration
is greater than the output voltage generated with the stator coils in the third configuration.
