    I got a schemetic from fairchild for Optically Isolated Phase Controlling. I modified a little bit on that schemetic before the Optoisolator. Please check my schemetic and reply any problem on my modified schemetic.

    I attached both schemetic, one is from fairchild and the other one I modified.

    Hello,

    If the one with the transformer is yours, it can lead to a phase shift due to the use of the transformer.

    Yes, transformer using schemetic is mine. I have an another schemetic from EFY Magazine. I attached here, please check it. It is using transformer. So if it lead phase shift, is my schemetic (phasecontrolmodified.jpg) works? At what degree phase shift lead?

    And I also want to know, i uploaded total 3 schemetic, anyone will work with square wave? (that mean Ac source from invertor)
