Circuit diagram for 12V DC supply to 220V AC supply (inverter) with 2000W output capacity?

Can anyone provide me with the details of an inverter circut that can convert 12V DC to 220V pure sine wave AC supply. It can deliver an output power of say about 2000W.

you just have to use a different secondary winding on output transformer to get to 220V.
And a word of caution: Yes, most $200.- types of inverters do not supply perfect sine wave, and in most cases you can get by. BUT I have experienced damage to electronic circuits, those that do not have a good power supply (like kitchen appliances) when I ran them with one of those “cheap” inverters!
