hi can anyone tell the circuit diagram for automatic voltage regulator for 50hz 220v thanks in advance

 

My electricity is reliable and its voltage is regulated. Its frequency is exact.
What is wrong with your electricity that you must regulate it yourself? Why?

Parunkumar: are you generating the power yourself, or does it come from a utility? Different sources require different techniques.
