2021年9月8日，来自剑桥大学的龙腾博士，应浙江大学电气工程学院之邀，于玉泉校区电机工程楼201室，进行主题为“Unlock the Potential of Wide Band Gap Power Electronics”的学术报告。报告会由电气工程学院院长盛况教授主持，电气学院师生40余人聆听了报告。
龙腾博士首先介绍了他所在的剑桥大学工学部，随后针对宽禁带功率模块所面临的损耗大、开关速度低等问题，通过对元器件合并同类项并简化的方式，系统介绍了一种新颖的集成型功率模块。然后介绍了SiC器件在运输电气化中的应用，包括电动汽车、电动船舶等，期间详细介绍了同步失效、QCM、RCP等先进软开关控制手段。接着针对无线充电，分享了一种利用金属合金代替铁氧体磁片的方法，显著提高了系统的效率和功率密度。
之后，龙腾博士同与会师生进行了讨论交流，并对大家的疑惑做出详细的解释和分析，现场气氛热烈。报告最后，盛况教授对龙腾博士精彩的报告作了总结，并致以诚挚的谢意，同时勉励与会师生在器件、电路和控制上进行深入交流和融合，充分利用超净间等优势，努力将电力电子学科发扬光大。
报告人简介：
Dr Teng Long has been appointed Lecturer at the University of Cambridge in 2016.He established the Applied Power Electronics Laboratory (The Long Group) and he is currently leading a research team comprised of 3 Postdoctoral Research Associates and 8 PhD students. His research portfolio covers from power electronic devices to power converters to drive and power systems, mainly for transport electrification and renewable energy applications. Since his Lectureship, Dr Long has been awarded more than 2.5 million research grants where half are funded by the UK government and the rest directly from industrial sponsors. Dr Long has built strong connections with industrial partners including the SAIC Motor, Dynex Semiconductor, STMicroelectronics, Siemens, CBMM, CRRC, Wuxi SES, Huawei, NIO, etc.
Prior to joining Cambridge, he has worked for General Electric (GE)where he has led or played an important role in many rewarding projects such as the first transformer-less all electric oil-platform supply vessel, the first large scale all electric warship (Type 45 Destroyer), and the first electromagnetic aircraft catapult demonstrator.
To date, Dr Long has more than 40 academic papers published at international journals and he is the inventor of 5 international patents. Dr Long received the B.Eng. from the Huazhong University of Science and Technology, China, the first class B.Eng. (Hons.) from the University of Birmingham, UK in 2009, and the Ph.D. from the University of Cambridge, UK in 2013. Dr Long is a Chartered Engineer registered with the UK Engineering Council.
