This is a quite simple DC to AC inverter that provides 220VAC when a 12VDC power source is provided. It can be used to power

very light loads like night lamps and cordless telephones, but can be modified into a powerful inverter by adding more MOSFETs. Ituses 2 power IRFZ44 MOSFETs for driving the output power and the 4047 IC as an astable multivibrator operating at a frequency of

around 50 Hz.

The 10 and 11 pin outputs of the IC directly drive power MOSFETs that are used in push-pull configuration. The output transformer

has a 9V-0-9V, 2 Amps on the secondary and 230V on the primary. Use suitable heat-sinks for MOSFETs.

Remember that this is not a sine-wave inverter, not even a modified one. Its just a square-wave one so you can power only light bulbs,

and small power tools that do not require a frequency with a sinusoidal wave form!
