Circuit knowledge

This Push-Pull Square wave DC-to-AC Inverter uses inverter gates for the oscillator part, then use one of the gate to invert the produced square wave signal. With push pull operation, the primary coil of the transformer is driven with alternate direction, with the help of H bridge of power transistors (MOSFET) 2SJ471 and 2SK2956.Using the transformer shown in the schematic diagram, this inverter schema produce 110VAC from 12VDC input, but you can easily modify this schema to produce 220VAC by replacing the transformer with 220V type (12V-220V) of the same amperage (10A).
