Abstract
A system for battery-based activation of a voltage regulator has a voltage detection circuit that measures the voltage produced by a battery, for example, an automotive system battery. The system further includes a voltage regulation unit, which is activated when the voltage that the battery produces is below a threshold value indicative of an attempt to start an engine. To begin regulation, a field current signal of a generator is strobed to create a battery voltage signal that exceeds the minimum reference value. If the battery voltage signal is above a minimum reference value, the battery voltage signal will be analyzed to ensure that neither voltage spiking nor a no load change condition caused the anomaly. Once these safety checks are complete, the battery voltage signal can be regulated.
