    Hello,
    I am in the process of implementing a universal dimmer(supports LVH,Fluorescent,Incandescent) for our project.But I am new to analog circuit implementation.
    Any help would be appreciated....

    Thanks in advance

    Just yesterday I refrained from telling someone, "Just because you can think of it doesn't mean it can be built". This is the kind of proposition that influenced Audioguru to commit virtual suicide.

    The triac dimmer will work for florescent and incandescent, though operation of such a dimmer with florescent can be a little awkward because the florescent lamps will not have large a dynamic range and will abruptly go dark as they are dimmed, while incandescent lamps will continue to dim, sometimes to apparent zero.

    Two ways that come to mind of dealing with the different dynamic ranges are 1) a switch to tell the dimmer what range to use and 2) a variation on the first idea, which is to have the dimmer sense the lamp type and adjust its range automatically.

    What is an LVH?

    Low Voltage Halogen. Typically 12v 50W halogen incandescents with a laminated AC drive transformer.
