    Dear Sir,
    I am trying to make an SMPS based power inverter, and i have completed the project almost 70%. Now i am facing problem about how to convert 340V DC into 50Hz AC. My question is :
    Is this possible to use H-Bridge circuit to produce AC from DC source

    An h-bridge circuit will produce a square wave. Unfortunately a square wave will not do. Most devices are sensitive to the waveform that is used to feed them. The signal generated must be an approximation to a pure sine wave.

    UPSs are not inside my area of knowledge. My knowledge about electronics is focused on linear power supplies and little more.
