초록

A system and method are disclosed for regulating a generator controlled power signal. An exemplary embodiment of the system may include both a digital voltage regulator and an analog voltage regulator and a selector switch configured to switch modulation control between the digital and analog voltage regulators. A watchdog detection circuit may be included for detecting an upsetting event in the digital voltage regulator and may trigger switching of the generator excitation input voltage modulation from the digital voltage regulator to the analog voltage...
