A much more simple and stable square wave to sine wave converter. The last 1k resistor and ground is to simulate a load.

Can you explain the operation

Resonance, that's how :p but if we tweaked this more, we could make it be perfect resonance and make it take off in voltage upping :)

I need 50Hz output so what rating of capacitor I should use here

100mH ? Bulky beast would be prone to emp and stray harmonics. Does it work only here or can it be done in real life? Can it be done for different values? I definitely need to try Fourier transforming this to find out if a sine wave can be ideally generated.

This can be built, I managed to get it to work with pwm (using a pic) but I had to modify it a little and the sine wasn't as clean as it is here.
