Zero-Crossing Detectors Circuits and Applications

A zero-crossing detector is used to generate a sync pulse related to the AC voltage phase angle often used in power control circuits. Fig. 1 shows the relationship of a zero-crossing pulse to a sine wave. The pulse occurs at 0, 180, and 360 degrees. Fig. 2. Fig. 2 shows how to use a H11AA1 opto-coupler to generate a TTL level pulse.
