    Hai,
    Currently I working on Dc to Ac resonant converter project using multisim software.This converter uses Zero voltage switching topology.It consists of two IRF 840 MOsfet Transistors with 500 KHz as switching frequency.Also the resonant frequency is 500KHz by designing the values of Land C for the resonant circuit.Converter uses Series Parallel loaded resonant converter topology.The load is connected in parallel with the resonant capacitor. The input supply is 270.The required output power is 500 watts.I am getting almost near that output power.But now I am facing the difficulty of poor efficiency to about 75%.Please give any suggestions for improving the efficiency to 90%

    Thank You Very Much

    We can't help you very much unless you post an image of your schematic.

    Posting the Multisim file won't help, as many don't have the Multisim software to read that file format.
