Abstract:
Phase angle control of SCR is incorporated using ATMEGA 328p. A microcontroller can be programmed to fire SCR over the full range of half cycles—from 0 to 180°—to get a good linear relationship between the phase angle and the delivered output power. The components are placed in a breadboard with AURDUINO board. The program is done in KEILµVISION. The program is stimulated and checked with Proteus Professional V8 software. Program burner used is FLASH MAGIC. In this project, an attempt has been made to trigger the SCR at any desired firing angle and to display it on an LCD
