    request....with UPS cct

    can anybody please help me....
    i want a simple UPS cct using full bridge IGBT or Mosfet with output 220/240v 50hz
    i need the driver cct for the IGBT or Mosfet as well....please...

    Welcome to PF.

    Critical factors are the power output and output type (square wave, modified sine wave, sine wave).

    Have you considered a computer or autoparts store?
    Probably cheaper than building your own.

    actually this is my eng. project. can i do it just by using dc power supply and connected it to an inverter?
    so that i can get the desired output (sine wave) and how can i measure the (THD) total harmonic distortion of the output wave?

    Well, this is your project.
    What would be the specifications for a DC power supply to run an inverter?
    You could use a meter to measure distortion or sample the output and run a FFT on it.
