Research Overview This research focuses on the design and implementation of high-power density power modules specifically optimized for AI servers. The work addresses the increasing power demands of next-generation computing hardware, presenting an integrated solution that balances efficiency and thermal management in a compact form factor.

🥈 Excellence Award

Analysis and Development of a 5.5 kW Three-Phase LLC Resonant Converter for Server Power Supplies

Authors

  • Prof. Yu-Chen Liu — Advisor
  • Shang-Hsun Wu — Award Recipient

Research Overview This paper presents a comprehensive analysis and development framework for a 5.5 kW three-phase LLC resonant converter. By leveraging three-phase interleaving and resonant control, the system achieves superior efficiency and power density, making it a critical technology for high-performance data center power architectures.

🥉 Honorable Mention

Efficiency Optimization of Multi-phase Interleaved Power Factor Correctors Based on an Adaptive Phase-Shedding Algorithm

Authors
