We are quite familiar about inverters which convert a DC potential to higher AC potentials at mains levels.
However these units involve complex and expensive configurations for acquiring the required outputs.
A much simpler approach of achieving the above results is by employing a oscillator mosfet boost converter circuit.
If the waveforms are not critical for your applications this method can be a lot simpler and cheaper to implement.
Referring to the circuit diagram below, we see that the entire idea is based upon the versatile, evergreen IC 555. Here it's configured in its standard astable multivibrator mode for generating the required pulses at a frequency determined by the resistors 4k7, 1k and the capacitor 680pF.
The output is received at pin#3 of the IC, which is fed to the gate of an N-channel mosfet. When power is switched ON, the positive pulses emanating from pin#3 switch ON the mosfet into full conduction. During the above periods the 12V high current potential is pulled to ground via the coil by the mosfet.
As we all know inductors always try to oppose instant changes in current polarity through it, therefore during the negative pulses when the mosfet remains switched OFF, forces the coil to dump the stored potential in it in the form of high voltage EMF pulse into the output. The above straightforward operation is repeated continuously at the given frequency providing  a sustained 220VAC at the output. The BC547 and its base network is introduced for limiting the output voltage to the required degree.
