论坛共包括3个主题。中美双方代表围绕每个主题分别发表报告。围绕第一个主题“新能源、新能源汽车、储能”发表报告的中方代表罗海辉博士,国家重点领域创新团队核心成员,现任株洲中车时代电气股份有限公司半导体事业部IGBT制造中心主任。报告针对IGBT在新能源领域应用的技术特点与发展趋势,介绍了新能源领域概况及应用需求;中车新能源应用IGBT芯片技术特点;中车新能源应用IGBT模块技术特点;中车新能源应用IGBT发展趋势等。

 

美方代表美国大功率直流电源制造商协会主席Stephen Oliver先生就这一主题也发表了报告,介绍了宽禁带半导体在可再生能源领域的应用,通过讲解功率晶体管的进展历程,比较了SiC、Si、GaN的不同特性,指出高效率和高密度功率器件在可再生能源领域的作用。

 

第二个主题是数据中心以及IT设备大功率直流电源。科华恒盛股份有限公司技术中心副经理兼预研部经理易龙强博士发表题为“数据中心不间断供电系统可靠性热点问题研究”的报告。针对数据中心不间断供电系统的热点问题进行分析与阐述,包括不间断供电设备对供电系统可靠性的提升作用、不间断供电系统构架可靠性分析与结论、数据中心可靠度与可用度之间的关系等,为读者从另一个视角重新认识数据中心不间断供电系统可靠性,并消除一些行业误解。

 

美方代表美国大功率直流电源制造商协会执委Conor Quinn先生发表了题为“信息技术和数据中心设备的架构转变”的报告。报告从效率、冗余、能源储存几个方面讲解了大功率直流电源架构革命的进程,并给出了具体案例。


论坛最后一个主题是关于消费类大功率直流电源:智能手机、笔记本电脑、电视等。台达电子(上海)研发中心主任章进法博士以“大功率直流电源适配器技术进步与发展趋势”为题发表报告。在对笔记本电脑和消费产品的交流适配器的市场趋势分析的基础上,报告讨论了关键技术的发展趋势和挑战,最后介绍了世界上最小适配器的设计细节。


Stephen Oliver先生就这一主题发表其在论坛的第二份报告。题目为“高频生态系统驱动新应用及新方案”。

 

论坛就每个主题都安排了问答时间,由每个主题报告人解答与会者提出的疑难问题,与会者踊跃提问,与报告人积极互动,会议现场气氛热烈。此外,所有主题结束之后的茶歇和酒会环节,与会者们就关心的话题和领域再次自由探讨交流。

 

中美大功率直流电源产业创新论坛的成功举办,为国内外大功率直流电源企业提供了一个良好的互动交流平台,有利于推动大功率直流电源行业技术进步和产业发展。

There were three topics at the workshop. Representatives from both CPSS and PSMA gave a speech respectively on the topic. Question and answer session followed.

The first topic was New energy Green cars and Energy storage. Dr. Haffee Luo, Director of IGBT MC, from Times ElectricCo. Ltd, Semiconductor Business Unit, gave a report on CRRC IGBT Technology and Application in New Energy.According to the technical specifications and trends of application in new energy which contains: New energy field summary and application demands; CRRC new energy application IGBT wafer specification; CRRC new energy application IGBT module technical specification; CRRC new energy application IGBT developing trend.

The other speaker of topic one was Prof. Stephen Oliver, presenting a speech on “Wide Bandgap Semiconductors for Renewable Energy Applications’’. By explaining the progress of power transistor, the speaker compared different characteristics of SiC, Si and GaN, and pointed out the role of high efficiency and high-density power devices in the field of renewable energy. 

The second topic was Data center,IT equipment power supply. Dr. Yi Longqiang, from R&D Department in KEHUA Corporate gave a report on“Research on Reliability Hotspot of Uninterruptible Power System for Data Center”.The report analyzed the hot issues of the data center uninterrupted power system, including uninterruptible power supply equipment how to enhance the reliability of power supply system, the reliability analysis and conclusion of the uninterrupted power system, and the relationship between reliability and availability of data center, etc.

The US counterpart,Conor Quinn, Artesyn Embedded Technologies Director of PSMA gave a speech on “Architectural Shifts in Information Technology and Datacenter Equipment” A. The agenda of the speech contains:What is Old is New (IT Equipment);Who pays the bills and Drivers for Architecture Decisions; Power Architecture Evolution(Efficiency, Redundancy,Energy Storage and examples).

The last topic of the workshop was about Consumer AC-DC (smartphone, laptop, TV, etc.)Dr. Alpha Zhang’s report title was“ Adapter Power Trend and Technology Development”.Based on the market trend analysis of acadapter for laptop and consumer products, Dr. Alpha Zhang discussed the key technology trends and challenges, and finally introduced in details of design of the world smallest adapter. 

In this part, Prof. Stephen Oliver came back to the rostrum and finished the last report of the workshop, which pointed High-Frequency Eco-System Drives New Applications, New Solutions.

In the end of each topic, the two speakers spared 15 minutes to answer the questions about the topic put forward by the listeners. Also, there was a networking and drinking session after all the presentations were done when participants could interact with speakers closely.The atmosphere during the workshop was active and warm.
