Pure sine wave inverter topology

[francis29]

The inverters i have seen all are low frequency tx based inverters. Like 12Vdc converted to spwm and uses low frequency transformer to get pure sine wave output. I s there any commercial inverters that uses different topology??

You have not mentioned any topology is specific. By the way, the most common to find in commercial products is the push-pull for relatively low powers, and the full-bridge for above.

The inverters i have seen

Most inverters I have seen, also most mentioned in various Edaboard are using a different topology. High frequency DC/DC + full bridge.
