    I have an inverter that puts out a nice 120v square wave. The inverters that
    put out a pure sine wave are expensive. Does anyone know where I can obtain
    schematics to build a square to sine wave converter fo my inverter? Thanks
    in advance.

  2. There must be a reason why sine wave inverters are expensive..... Pehaps you
    should find out why.

    It may be the expensive of the square to sine coversion may be more
    expensive than a direct pruchase of a sine wave inverter... after
    considering the design, labor and material costs.

    Aaah! Google gave lots of hits... including this one.

    Seems the complexity of design.... and cost of parts are what you are paying
    for...... If I spent years on a design.... I wouldn't give it away for free.
