Using this circuit you can convert the 12V dc in to the 220V Ac. In this circuit 4047 is use to generate the square wave of 50hz and amplify the current and then amplify the voltage by using the step transformer.
Attention: This Circuit is using high voltage that is lethal. Please take appropriate precautions

Most car battery chargers are simple devices that continuously charge the battery with a few amperes for the duration it is ON. If the charger is not switched OFF in time, the battery will overcharge, its electrolyte lost due to evaporation, and its plate-element will likely be destroyed.
The circuit above will eliminate these problems by [...]
This Audio amplifier has output 18 Watt RMS into 8 Ohm (1KHz sine wave) and Frequency response 30Hz to 20KHz -1dB. It’s simple to build and you don’t need preamplifier. Few notes about this circuit.
Do not exceed 23 + 23V supply.
Can be directly connected to CD players, tuners and tape recorders.
D1 must be in thermal [...]
