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.

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.
