300 watts pure sine wave inverter circut schematic

[mide]

Hi all

I am interested in building a reliable and efficient pure sine wave dc to ac inverter.

i would appreciate, a well detailed circuit schematic that can help me this with breakdown of the inversion process.

Thanks

mide,

You didn't say what your input voltage or your output voltage needs to be. But, I doubt that you are going to be able to build a reliable sine wave inverter as cheaply as you can buy.
