2025 National Taipei University of Technology Capstone Project Exhibition
ECIE Lab Showcases Seven Advanced Power Electronics Projects
On December 2, 2025, the Department of Electrical Engineering at National Taipei University of Technology held its annual Capstone Project Exhibition. As part of the event, the ECIE Lab presented seven student-led research projects, reflecting the lab’s long-term commitment to hands-on engineering education and innovation in high-frequency power electronics.
Early Technical Training and Research Development
Students in the ECIE Lab begin preparing for their capstone work as early as their sophomore year. Through structured coursework, laboratory training, and continuous technical mentorship, they gradually build the foundation required for independent research. By their junior year, each student initiates an individual capstone project, applying accumulated knowledge to real-world converter design, modeling, and hardware implementation.
During the exhibition, students presented their final results to faculty members from the Department of Electrical Engineering. Presentations emphasized design methodology, simulation and modeling techniques, hardware validation, and the engineering decisions made throughout the development process.

Engagement with Students Across the University
Throughout the event, the ECIE Lab welcomed numerous visitors from various academic programs. Student presenters engaged in technical discussions, offered demonstrations, and shared their research journeys—from initial concept refinement to final prototype evaluation. These conversations provided younger students with a clearer understanding of research opportunities within the lab and the broader field of power electronics.
Commitment to Training the Next Generation of Engineers
This year’s capstone projects highlight the depth of student training within the ECIE Lab. By combining rigorous academic preparation with practical engineering challenges, the lab continues to cultivate young researchers capable of contributing to next-generation power conversion, high-frequency magnetics, and system-level innovation.
The ECIE Lab looks forward to supporting future cohorts as they develop advanced solutions for the rapidly evolving power electronics industry.
