AC Power Strength Controller System
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.
