CONTROL SYSTEM FOR AN APPLIANCE

摘要

A control system for determining a magnitude of a voltage and controlling an application of the voltage to at least one load device of an appliance is disclosed. The control system includes a threshold-crossing circuit configured to receive a representation of the voltage and to provide an output signifying the voltage crossing a predetermined voltage threshold; and a processor which receives the output from the threshold-crossing circuit and determine the magnitude of the voltage based on the output and a line frequency based on the period of the output, determines an initial cooking profile from a group of cooking profiles based on a user selected initial setting for controlling the application of the voltage to the at least one load device, and adjusts the application of the voltage to the at least one load device based on the determined magnitude of the voltage.
