The project aims at controlling the AC power by using the concept of firing angle control of thyristors. One can enter the required percentage of power supply through a keypad. The input is provided to a microcontroller of 8051 family that initiate the firing angle to adjust the load power. For matching the power to the required one, a TRIAC is used in series with the AC load. A LCD screen is used to display the power percentage that is provided by the user.
