Teaching Power Electronics Converter Experiments using Fuzzy Logic Approach This paper presents a fuzzy logic approach to teaching about power electronics convertersin the laboratory. The approach is based on model-free software-hardware platform for use inconverter experiments in a basic power electronics course. This course is an optional subject,and, therefore, the experiments need to motivate the students. The platform is controlled bymodel-free software run on a personal computer (PC) and is an ideal complement for theoreticalstudy. The student can control the fundamental parameters of the converter topology through theuser interface. The user interface is designed to provide simple interaction between student andsoftware. This environment allowed for extensive experimentation, performance comparison,and development of several practical control algorithms. Students also improved their writtenand oral communication skills as well as experimental proficiency from the hands-on approach.In addition, working in a team of diverse students encouraged constant discourse and exchangeof ideas through the course of the design of the controllers. All students have reacted positivelyto the experiments and overall interest has definitely been increased. The fundamental educational objectives are: 1) to provide hands-on experience inpractical power electronics applications, 2) to reinforce and support lecture-based courses inpower electronics, and 3) to train a new cadre of graduates who value experimentation as anessential and natural part of solving engineering problems. Hence, the undergraduate engineeringeducation becomes more attractive and meaningful to the students. The author found thelaboratory experiments to help reach the goal of lab-based teaching. The experiments definitelyrequired critical thinking by the students. It is expected that the techniques employed in thecontroller designed for the laboratory experiments will likely be used by the students in theirsubsequent employment after completion of their college education. Student opinions of the labexperience, as determined through anonymous surveying, are also presented in the paper andways to improve the lab based on these feedbacks are discussed.
