you will learn zero crossing detector using op amp designed using the popular 741 IC. We have a neat draw circuit diagram of zero crossing detector and we have explained its working principle and theory behind the scene in easy to understand words...
then it is very important to have just pulse indicating the change of zero crossing. As whole square wave is not much useful. To solve this problem we add a positive edge detector circuit after the output of operational amplifier so that we get only pulse indicating...

Furthermore, any doubts regarding this concept orelectrical and electronics projects, please give your valuable suggestions by commenting in the comm...
Zero-Crossing Detection with False Trigger Avoidance Shubham Sahasrabudhe, Data Converter Products Overview A zero-crossing detector (ZCD) is used for detecting zero-crossing of AC signals. Applications of ZCDs include the use in protection relays, AC analog input modules, smart energy meters, ...
A noise filter for the zero crossing detector of a digitized sine wave signal uses an adjustable noise integrator. The noise integrator incorporates a counter. The integration characteristic of the co
The sensorless rotor position detector detects the Zero Crossing points of Back-EMF induced in non-fed motor windings. The obtained information is processed in order to commutate energized phase pair and control the phase voltage, using Pulse-Width-Modulation. 3-Phase BLDC Motor Control with ...
