110V ac from 12V DC generator based on 89S2051

Didik Rostyono developed nice converter from battery povered 12V DC power supply to 110V and 50Hz wave.

To acchieve this he used microcontroller 89S2051, MOSFET switching circuit and transformer. Output signal then is filtered where higher harmonics of signal are filtered and signal appears to be sinusoidal. It is hard to say what loads this circuit is cappable to drive, but this design [perfectly suits for learning purposes.
