ECIE Lab Receives Best Paper Award at IFEEC 2025 Bali

by · Published · Updated

ECIE Lab at the National Taipei University of Technology is proud to announce that our researchers have received two Best Paper Awards at the International Future Energy Electronics Conference (IFEEC) 2025, held in Bali, Indonesia. These awards highlight the laboratory’s continued leadership in magnetic design, machine-learning-assisted modeling, and high-efficiency power conversion technologies.

Award 1: Inductor Design Optimization Framework Using Machine Learning

Authors

  • Mr. Yung Chi Chiu — Author and Presenter
  • Dr. Yu-Hsin Wu — Advisor
  • Dr. Chen Chen — Advisor
  • Prof. Yu-Chen Liu — Advisor

Research Overview

This work presents a machine-learning-based framework that dramatically accelerates magnetic inductor design. Traditional workflows require thousands of time-consuming 3D finite-element simulations. In contrast, the proposed method constructs surrogate models—trained using measured B–H curves and 3D eddy-current simulations—to predict inductance, core loss, and copper loss with accuracy exceeding 0.99.

The resulting model enables efficient exploration of design trade-offs, such as footprint versus total loss, while incorporating realistic constraints. This framework significantly reduces design time and provides a scalable foundation for future magnetic component optimization, including transformers for electric vehicles, renewable energy systems, and data-center power architectures.

Award 2: Simulation-Driven Design of a Fully Enclosed Secondary-Winding Transformer for High-Current PSFB Converters

Authors

  • Tzu-Yang Hsiao — Author and Presenter
  • Prof. Yu-Chen Liu — Advisor

Research Overview

This paper introduces a fully enclosed secondary-winding transformer (EWT) design optimized for high-current phase-shifted full-bridge (PSFB) converters. By improving magnetic coupling, reducing AC losses, and minimizing leakage inductance, the design enables compact and efficient power delivery without added control complexity. The proposed approach serves as a practical magnetic solution for next-generation low-voltage, high-current power systems.

Reflection on IFEEC 2025

IFEEC 2025 provided valuable opportunities for ECIE Lab to share research with the global power electronics community, engage in technical discussions, and explore emerging trends. Receiving two Best Paper Awards is a meaningful milestone that reflects the efforts of all our researchers and advisors.

These recognitions strengthen our commitment to advancing magnetic component design, simulation-driven engineering, and multi-disciplinary optimization. ECIE Lab will continue fostering innovation while supporting the next generation of engineers and researchers in the field of power electronics.
