Re: Square to sine wave

Use a low pass filter to pass only the fundamental.
You would need large capacitors that can handle high ripple current and large inductors with low resistance windings.
Generally not considered worth the trouble when there are plenty of commercial sine wave inverters available.

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.
