GaN’s Tipping Point – Why GaN in AI Server?

In facing the transformation of energy efficiency, EPC and Power Electronics Lab of NTUST embrace the same vision of contributing to create a better world supported by extensive applications fuelled by gallium nitride-based power electronics technology.

Introduction - AI Server Demand Accelerates DC-DC and AC-DC Converter Development

Speaker: Josh Feng

Session 1: Exceeding 5kW/in3 in a high density 48V-12V DC-DC converter

Speaker: Michael de Rooij

Details of a 1kW reference design, with performance measurements, will be presented that covers device choice, transformer integration and over-coming testing challenges.

Session 2: Using a multi-level PFC topology to shrink the physical size while exceeding 99% efficiency in an AI PSU (power supply unit)

Speaker: Michael de Rooij

Multi-level PFC has proven to increase power density in high power server PSU without compromising efficiency. Details, including design and measurements, of a proof of concept converter will be given followed by design details of a 4.8 kW version. The synergy between AC-to-DC conversion leads to expansion of multi-level topology in motor drives and details of the benefits and approach will also be covered.

Session 3: High-density high voltage to low voltage isolated Conversion

Speaker: Michael de Rooij

The final section presents work on the isolation stage in the complete converter chain that meets the safety requirements between the grid and server. Two approaches will be covered; 1) a phase shift resonant bridge converter with active clamp and 2) a 4 cascade LLC converter with very high power density.

5,000 Watts/in3 Power Density in a 48-12 V Bi-directional DC-DC Converter for AI Servers Thursday, March 21, 2024 - 11:10 - 11:35 a.m. Japan Standard Time (JST)

Speaker & Live Q&A Session: Dr. Michael de Rooij

GaN devices increase the power density and efficiency, reduce system cost for the DC power systems used for high-density computing applications such as AI servers. GaN® FETs and ICs provide the fast switching, small size, and high efficiency needed to provide the highest power density solutions which is the ideal solution to address the growing power needs of artificial intelligence and to support the transition to 48 V input for the new high density and high efficiency servers required for these advanced computing applications.

Details of a 1kW reference design, with performance measurements, will be presented that covers GaN device performance, transformer integration and over-coming testing challenges.

无人机逆变器中GaN FET相对MOSFET的优势 - 实验结果比较

讲者:Marco Palma

电池供电的无人机正在彻底改变当今的农业,用于喷洒肥料等。 这些无人机使用的电机驱动器需要轻便且高效,以最大限度地延长电池寿命和延长充电前的飞行时间。宽带隙器件,特别是GaN FET,已被证明可以改善电动运输和机器人应用中的BLDC电机驱动器。我们将介绍GaN FET如何可以更轻和提高电机驱动系统的效率。

我们对采用GaN FET的逆变器进行了实验测试,并与驱动农业用无人机的永磁电机、基于等效MOSFET的逆变器进行了比较。 最相关的品质因数被描述为电机速度和功率的函数。
