Manual Voltage Stabilizer Block Diagram

For the microcontroller circuit we use an external crystal of 4 mhz.

Manual voltage stabilizer block diagram.

This is required because there is no internal crystal present in pic 16f873a. 220v ac input supply from supply line and flow the ac voltage of rectifier. The diagram demonstrates an extremely very simple voltage stabilizer design which are able to maintain massive output power approximately 5 to 10kva. The circuit diagram comprises following four sections.
