Controlling AC loads power is important application in many areas. We can control the power of a device by firing the triac at specific angles. For that we should know where the AC signal is crossing 0. Zero cross detector exactly does that..it will give a pulse whenever AC signal crosses 0. We can configure the controller in interrupt mode to capture this event and can fire TRAIC to control the power supplied to the load.
