    hi all,

    i am trying to simulate a power factor corrected AC/DC converter.
    It has two flyback converters connected in parallel.
    one converter regultes the input power factor and the other converter regulates the output dc voltage.
    I was able to get close to unity power factor and tight output voltage regulation with this method.
    But to my surpise i found that the output power of the circuit is greater than input power. how is this possible?? any clue about what might be the reason for this?? can anyone please help me out......

    Thanks
    Ashwini

    Can you post up the circuit schematic and the voltage and current readings?
