ABSTRACT:
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.
