The article explains a very simple method of acquiring 220V AC from a 12v DC source. The idea utilizes inductor/oscillator based boost topology with the help of the IC 555.

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.

### Circuit Description

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 duty cycle may...
