Inverter circuit design

[pgr2002]

I want to build an 875-1000 (va) inverter from 12v battery.
Does anyone has come across inverter circuit designs. If so can anyone give circuit ideas. The circuit should be simple and the components easily available.

A "simple" inverter has a square wave output that many electronic products cannot use. Its output voltage will be too low with a heavy load and will be too high with a light load. Its frequency will not be accurate. It kills the battery when the battery charge runs low. It and maybe the battery are destroyed if it is overloaded.

A complicated inverter has a pure sine wave output, voltage regulation, an accurate frequency, shuts off when the battery charge gets low or when it is overloaded.

An inverter in between has in between spec's.
