Abstract
A generator wake-up system that transitions the voltage regulator from a low power, sleep mode to full voltage regulation mode when the wake-up system detects and confirms a valid frequency of rotation of the generator. The wake-up system includes a control circuit to filter, amplify, and detect the proper threshold of an input waveform; and an assessing device that implements a control algorithm to measure and validate the input waveform.
