A permanent magnet generator voltage regulation system controls the output
voltage of a permanent magnet generator. The output voltage of the
permanent magnet generator is controlled by configuring the electrical
connection of the stator coils. A monitoring device monitors the output
voltage generated by the PMG, and a controller selectively configures the
stator coil configuration based on the monitored output voltage. A switch
array having a number of switches is connected to the stator coils, the
switches being controlled by the controller to configure the electrical
connection of the stator coils. For instance, to maximize output voltage
generated by the PMG, the controller causes the switch array to connect
the stator coils in series with one another. To reduce the output
voltage, the controller causes the switch array to connect at least some
of the stator coils in parallel with one another. In this way, the output
voltage of the permanent magnet generator can be coarsely controlled.
