    This is a power supply circuit I found while working on a project. I have been trying to analyse it but I am not getting the point of using Zener2 & Zener 3 in the circuit.
    If anybody comes to know what it acts like or can relate it to something you already know, please send me a response.
    Thank you.

    From the circuit that I think it is a tranformerless, and this is not allowed to discuss in this forum.

    The owners of All About Circuits has elected not to host discussions of transformerless threads.

    Transformerless powersupplies are not allowed over here.
    See point 6 of the user agreement:
    http://www.allaboutcircuits.com/user-agreement/

    If you wish to change to using the transformer to discuss then please press report, when our mods through the discussion, if we decide to reopen it then we will reopen.

    Good luck.
