    is this the right way to go about doing it?


    Get about 92 volts AC from a transformer.

    Connect this to a bridge rectifier to give you pulsing DC with peaks of about 130 volts. (92 times square root of 2 is 130 )

    Connect a large capacitor of 5000 uF rated at 200 volts or more across the output of the bridge rectifier.

    Take the output from across the 5000 uF capacitor. This will be close to 130 volts.

    More like 128.8, but close, yes.

    hi'
    here is an answer for u....
    first of all we really don't need any transformer while working with bridge rectifier..... If to get output of ur requried the connect a load resistor across the rectifier../......;please reply to this suggestion/ instead of transformer u can use ac regulated power supply
