Investigate Power Efficiency in PLECS and MATLAB Software by Designing USB 5Watt Charger

Abstract

In power electronics, accurately assessing simulation tools is key for precise, reliable electronic system designs. This study compares MATLAB Simulink and PLECS in modeling a 5W USB charger's power characteristic. The charger, using an AC-DC full bridge rectifier and DC-DC flyback topology, delivers a stable 5VDC at 1A. The analysis focuses on power efficiency and thermal characteristics, incorporating real-life components for detailed insights. Results show PLECS, specialized in power electronics, surpasses MATLAB in accuracy and consistency. This research aids in understanding simulation tools' effectiveness, guiding engineers and researchers in power efficiency evaluations for electronic systems.
