    The link was posted nearly two years ago.

    The site probably no longer exists.

    This is why it's important to attach, rather than link, whenever possible.

    Indeed! This thread is almost 2 years old.
    I wonder what actually happened to the o/p.

    If you want the new link for a file that may have moved, just put the filename into google. I did, and found the new location:

    Google is your best friend...unless you live in China.

    Be carefull and true...

    I see a person requesting serious informations...

    A true sine wave inverter does not have to be dificult, but some thing has to be right...
    Schematics with gate drives of fets, with pull-up or down resistors does not work
    If a high effective inverter has to be build, the gate drive of the fet's has to be fast, otherwise everything turns into heat, due to slow turn on and off the fets.

    My sugesting to an effective inverter is:
    make a high frequency stepup (push pull) converter through an ferrite core.
    Thereafter on the high voltage rail, make a pwm sine wave output stage for the desired voltage and frequency.
    Regards
    Jesper

    Still holds true.
