Abstract: Threshold-based zero-crossing detection is provided. A power phase threshold detector detects when absolute value of a voltage level of the electrical power rises above a non-zero voltage threshold and outputs a zero-crossing signal to a controller to indicate occurrence of the zero-crossing. Delaying the zero-crossing signal to the point when the absolute value of the voltage level of the electrical power rises above the non-zero voltage threshold ensures completion of the zero-crossing of the power phase prior to signaling the controller. The controller provides signals to a switching circuit for controlling switching of electrical power to a load based on the zero-crossing indications.
