    i give 110V Dc to birdge through single pole MCB & output site of bridge i connect load.
    i observe following points
    1. when MCB is OFF I SEE 220V DC instead of 110V DC.
    2. when MCB is ON I see 110V DC.
    SO PLEASE TELL ME WHY THIS HAPPEN & HOW???????????????

    Please post your schematic, what is an 'mcb'?

    I believe Miniature Circuit Breaker?

    I presume the MCB is between AC and the bridge? Is the load still connected when you get the 220vdc?
    Is any point from the secondary on at earth ground?

    Post the schematic of your circuit and indicate where you are taking these measurements.

    Why did you choose to input 110V DC into a diode bridge?
