Enhancing Engineering Education through Innovative Laboratory Design

Abstract

This paper presents the use of a new experimental setup for power electronics and electrical drive experiments in teaching Electrical and Electronics Engineering bachelor students. The setup is developed in the context of educational innovation and is configured to closely resemble industrial appliances that are used in power electronic converters for DC-DC, DC-AC and AC-DC conversion. The hardware allows students to perform laboratory experiments with voltage levels below 60 volts and under 200 Watts, to comply with DC grid LVDC standards. Applications range from battery charging, solar panel maximum power point tracker, DC-DC conversion to single phase and three phase AC applications such as motor drives, grid-tied connected inverters and wireless power transfer. Moreover, the applications can be tailored to apply in other disciplines, such as Mechanical Engineering and Mechatronics. A set of experimental assignments guides students from theoretical principles, via idealized simulations to measurements. Finally, students perform laboratory experiments in which they are assessed on their verification of the theoretical and simulation results together with measurement outcomes. Since the setup is constructed in the same way as an industrial application, typical measurement results due to parasitic components, are visible to the students. Compared to commercial educational training hardware, the industrial construction is more close to reality and better prepares students to understand the working of power electronics and electrical drives. The combination of the industrial design approach and multidisciplinary flexibility of hardware, laboratory experiments provide students a realistic and enhanced learning experience.
