Hello,
I am trying to implement a dimmer circuit with AT89C2051 controller. I am using a Transformerless Capacitive Power Supply. I need a Zero Cross Detector circuit directly from 230V mains to make the dimmer work.
Previously I had successfully implemented the dimmer using a linear power supply with a 12-0V transformer and a comparator for implementing the ZCD.
Please share if anyone has any idea regarding Zero Cross Detector circuit directly from 230V mains, whose output can be fed to the controller which I am using.
Thanks..
