Systems, Methods, and Apparatus for Sensing AC Voltage |
摘要 |
Certain embodiments of the invention may include systems, methods, and apparatus for sensing AC voltage. According to an example embodiment of the invention, a method is provided for sensing AC voltage. The method includes providing a voltage sensing circuit in communication with an AC power source; rectifying an AC signal from the AC power source with rectifier circuitry of the voltage sensing circuit; applying a first voltage to an analog-to-digital (A-to-D) converter circuit, wherein the first voltage is across a second resistive element of a first half cycle voltage divider comprising a first resistive element and the second resistive element and in communication with a positive DC output of the rectifier circuitry; and analyzing the first digital voltage value and the second digital voltage value by a processor to determine a voltage of the AC power source.
