Voltage regulator control circuit

摘要

A generator (18) wake-up system that transitions the voltage regulator (26) 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 (18). The wake-up system includes a control circuit (36) to filter, amplify, and detect the proper threshold of an input waveform; and an assessing device (48) that implements a control algorithm to measure and validate the input waveform. <IMAGE>
