  • Input voltage sensing using zero crossing detection
    Patent number: 10873326
    Abstract: Systems and methods are provided for measuring input voltage in an alternating current (AC) system is provided. The method includes measuring a half-cycle time of an AC signal by: detecting, using a zero crossing detector (ZCD), a first edge of the AC signal; in response to detecting the first edge, using a timer to determine a start time; detecting, using the microcontroller, a subsequent edge of the square wave output of ZCD signal; and, in response to detecting the subsequent edge, using the timer to determine a stop time and a length of time that lapsed from the start and stop times. The method further includes determining an overall value that corresponds to at least one length of time, determining, based on the overall value, an input voltage range that corresponds to the overall value, and using the input voltage to cause the AC system to take an action.
