This is a group project at Cardiff University to produce a 24 volt ac to 0 to 15 volt DC with 1.5 amp current limit.
The project was to be fully micro-controller based (message me if you want the code). The design has been tested and works.
Features include soft power button, Fine voltage tune, show measured or target values on the LCD, adjustable voltage and current limit,
PID software loop to regulate the output voltage and maintain the current limit and over temperature detection.
