Abstract
A system for monitoring the quality of voltage supplied by a power supply includes a voltage variation detection module and a controller. The voltage variation detection module has one or more level detection circuits that each receive a signal indicating the supplied voltage, thereby producing an amplitude signal representing a temporal variation in the voltage during a capture interval. The controller determines the capture interval, provides a capture control signal that causes the level detection circuit(s) to receive the voltage during the capture interval, receives the respective amplitude signal(s) from each of the level detection circuit(s), and produces one or more output signals, each representing the amplitude signal(s) and the associated capture interval, thereby providing an indication of the voltage quality. A method of using the system is also disclosed.
