Design and implementation of LED solar simulator

Abstract

In this paper, a complete LED-based solar simulator prototype is designed and implemented. The proposed light source of this solar simulator is formed using only six different types of LEDs to simulate the AM 1.5G spectrum. In addition, the flyback converter is designed to provide the required power of the solar simulator. In order to monitor and adjust the temperature at Standard Test Conditions (STC) of 25 °C, a proposed PID controller is applied and implemented using Arduino Mega 2560. The LED-based solar simulator prototype implementation has been achieved. The performance of the solar simulator prototype has been verified and tested.
