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.

無人機逆變器中Gan FET相對MOSFET的優勢 - 實驗結果比較

講者:Marco Palma

電池供電的無人機正在徹底改變當今的農業,用於噴灑肥料等。 這些無人機使用的馬達控制器需要輕便且高效,以最大限度地延長電池壽命和延長充電前的飛行時間。寬帶隙元件,特別是GaN FET,已被證明可以改善電動運輸和機器人應用中的BLDC馬達控制器。我們將介紹GaN FET如何可以更輕和提高馬達控制系統的效率。

我們對採用GaN FET的逆變器進行了實驗測試,而且與驅動農業用無人機的永磁電機、基於等效MOSFET的逆變器進行了比較。 最相關的品質因數被描述為馬達速度和功率的函數。
