Abstract
A method for implementing voltage regulation for an electrical generator device includes comparing an output voltage of the electrical generator device to a desired set point voltage thereof, and generating an output control signal configured to regulate a field current of the generating device. The output control signal is generated in accordance with a linear mode of operation during of one of an overvoltage condition and an undervoltage condition with respect to the desired set point voltage, and wherein the output control signal is automatically set to a predetermined value in a non-linear mode of operation during the other of the overvoltage condition and the undervoltage condition.
